With China 's rapid economic development , the demand for cement is growing. Cement production, raw material conveying Screw conveyor is one of the devices . Screw in the

application hanging bearing often occur at blocking material, the flash conditions affecting production , economic efficiency decreases. For screw conveyor

Machine to analyze this situation : the food conveyor helical blade hanging bearing is that the role of the place, where not only will accumulate a lot of material , but also

in the box at the bottom of a lot of hard grinding granular material deposition , which is difficult to broken iron grain , coarse particulate material content of more, and

Very dense , so that both ends of the conveyor screw shaft friction blades severely , both ends of the blades wear more severe ; screw conveyor hanging bearing increased wear

and reduce service life. To solve the above problem, screw conveyor manufacturing has done in the following improvements:

At both ends of the screw shaft screw conveyor welding two helical blades , to strengthen the hanging bearing thrust plot material . Screw conveyor screw shaft rotation , thrust

generated twice the material , reducing the area of ​​the hanging bearing material, will not happen again blocking material, the flash phenomenon . Screw

The hanging bearing on the improvement in the process : hanging bearing wear-resistant materials ( such as iron ) made ​​; or steel castings , steel castings bore quenching,

coupled with the cylindrical axis of the middle section of quenching, after quenching grinding ; or hanging bearing bore and shaft coupling covered cylindrical electrode wear a

tie

Enhance the abrasion resistance , extending bearing life hanging . After improvement , screw conveyor hanging double the life of bearings , greatly reducing maintenance costs,

while reducing the cost of production of cement , increase economic efficiency.

Easy maintenance.

Roller conveyor for conveying the bottom is flat goods, mainly by the drive roller, rack, bracket, drive unit and other components. With throughput, fast, running light, to

achieve multi-species collinear shunt transport characteristics.

Structure: there is power from the drive into the formal, non-powered, electric rollers, etc., according to the layout is divided into horizontal conveyor, inclined conveyor and

turning conveyor.

Transportation equipment according to the classification used for purposes

1, bulk material handling equipment (eg: belt \ Screw \ bucket elevators \ inclined conveyor)
(A) by a conveyor belt tensioning device drives the central structure and composition of the industrial conveyor as towing and carrying member, so as to continuously fed into pieces

scattered and fragmentary materials or goods.

Friction drive conveyor is a continuous manner for material transport machinery. Apply it, the material can be transported in a certain line, the feed point from the initial to

the final discharge point between the formation of a material transfer processes. It can be granular material Telescoping conveyors can also be

For a delivery of items. In addition to the purely material handling, but also with various industrial enterprises in the production process requirements matching process, the

formation of the rhythmic flow transport line. So conveyor is widely used in a variety of modern industrial enterprises.

In the underground mine workings, mine ground transportation systems, open pit and processing plant, widely applied conveyor. It is used for horizontal transport or inclined

transportation.

Universal conveyor from the conveyor belt, roller, roller and the drive, brakes, tension, bend, loading, unloading, cleaning and other equipment components.

① conveyor

Commonly used with two kinds of rubber bands and plastic. Rubber band for working environment temperature -15 ~ 40 ° C between. Material temperature does not exceed 50 ° C.

Upward transport of Granules inclination 12 ° ~ 24 °. Available for large transmission angle tread rubber band. Plastic belt with oil, acid,

Alkali, etc., but for the poor adaptability to climate, slippery and aging. Bandwidth is the main technical parameters of belt conveyor.

② roller

Of single drum (tape on the drum wrap angle of 210 ° ~ 230 °), double drum (wrap angle of 350 °) and multi-cylinder (for power) and so on. There trough roller, flat-shaped

roller, spherical roller, buffer roller. Trough roller (2 to 5 by the roller composition) supporting bearing branches to lose

Send granular materials; aligning roller to adjust the lateral position with, to avoid deviation; buffer roller mounted in place by the material in order to reduce the impact of

material on the belt.

③ drum

Minute drive rollers and bend pulley. Drive rollers are main components of power transmission. Of single drum (tape on the drum wrap angle of 210 ° ~ 230 °), double drum (wrap

angle of 350 °) and multi-cylinder (for power) and so on.

④ tensioning device

Its role is to achieve the necessary belt tension, in order to avoid slipping on the drive roller, and to the conveyor belt between the deflection rollers ensure that the

required range.

The technical advantages of belt conveyor

The first is its reliable operation. Require continuous operation in many important production units, such as the transport of coal power plants, steel mills and cement

conveying bulk materials, as well as loading and unloading of ships in ports all adopts belt conveyor. If the shutdown these occasions, the loss is enormous

. If necessary, take a class to a group of belt conveyor can work continuously.

Conveyor low power consumption. As the material almost no relative movement of the conveyor belt, not only the running resistance (about 1/3-1/5 scraper conveyor), but also the

wear and broken cargo are small, high productivity. These are conducive to lower production costs.

Conveyor belt conveyor line adaptable and flexible. Line length according to need. Short as a few meters, length up to 10km or more. Can be installed in a small tunnel, ground

transportation can also be set up in the region over the chaos and danger.

According to process requirements, can be very flexible belt from one or more points by the material can also be more or several sections to discharge. While simultaneously at

several points on the feeding conveyor (such as the Coal bunker conveyor) belt length direction or along either alike

Over uniform feeding device to feed conveyor, the belt has become a major transport route.

Coal stockpile conveyor can stockpile reclaimer roadway below, when necessary, but also to the heap of different materials are mixed. Materials may be simply discharged from the

conveyor head, but also by moving plow unloader or unloading vehicle longitudinal direction of the belt at any point discharge.

(2) commonly known as the auger screw conveyor is suitable for granular or powdered materials horizontal conveyor, inclined conveyor, vertical transportation and other forms.

Transmission distance varies according to deformity, usually from 2 meters to 70 meters.

Conveying principle: rotating spiral blade for screw conveyor passage of the material transported. So that the material does not rotate together with the screw conveyor blades

is the material force of its own weight and the frictional resistance of the material conveyor chassis.

Features: Screw rotating shaft is welded spiral blades, blade face delivery of materials based on a solid surface different type, belt type face, leaves and other types of face.

Screw conveyor screw axis in the direction of movement of the material with the thrust bearing to the terminal with the material to spiral

Axial reaction force, the captain longer, should be added to intermediate hanger bearings.

Two screw conveyor is to have two rotating blades were welded with the rotary shaft screw conveyor. To put it plainly, is to two conveyor organic combination, consisting of a

screw conveyor.

Screw rotation axis of rotation, determines the conveying direction of the material, but generally in the design of the screw conveyor are transported in accordance with the

individual blades of rotation. When the reverse transport, it will greatly reduce the service life of the conveyor.

(3) the use of bucket elevators uniform traction member fixedly connected to the series of unprovoked hopper, vertical continuous upgrading of materials handling machinery.

Bucket elevator with transmission capacity, high hoisting height, stable and reliable, long life and significant advantages, its main properties and parameters in line with

The different options conveyor

1, powerful fabric conveyor belt conveyor referred Powerful: including nylon conveyor belt (nylon canvas conveyor belt), polyester bucket elevators belt (polyester canvas conveyor belt), nylon - polyester mixed fabric conveyor belt. For medium-span transmission lines, conveying powder, granular and block

Like non-corrosive materials. Such as coal, sand, stone and so on.
High strength, good elasticity, impact resistance canvas after treatment by setting the initial high elongation at break large, constant load elongation is small, so the tape, high strength, good elasticity, flexibility, impact resistance. Small elongation after vulcanization adhesive tape, heat stretching, cold setting treatment, the use of tape over the

Small elongation process. The canvas layer is attached to the canvas through a special high strength impregnated improved adhesive strength of rubber and canvas, tapes difficult to cause delamination in use which lead to early damage. With a thin body, light weight, high strength canvas for the tensile layer is relatively common

Conveyor belt layer reduction measures can be implemented.

2, Nylon (NN) Turn conveyor: nylon cord conveyor belt body has a thin, high strength, impact resistance, good performance interlayer adhesion strength, excellent flex and long service life, suitable for long-distance, higher load transportation of materials under high-speed conditions. According to different cover properties

Divided into common type, heat-resistant, flame-type, cold type, acid type, oil type.

3, polyester (EP) conveyor belt: good elasticity, impact resistant polyester canvas full of unique flexibility, can well absorb shocks. Constant load elongation is small, the use of elongation polyester canvas belt constant load elongation properties than nylon and other fabric conveyor belt conveyor belt, in use can be

Exporting to shorten the trip, saving equipment costs, and materials suitable for long distance transport. Water resistance and good wet environment, the strong adhesion of the tape does not reduce the temperature, extending the life of the tape. Good heat resistance, corrosion resistant thin belt body can light weight due poly

Ester canvas strength, about 2.5-9 times the cotton sails, and cotton canvas conveyor belt ratio can be reduced layer, so the body with thin, light weight, good trough ability, both to improve transportation and reduce transmission power and pulley diameter can be reduced relative to another, to achieve energy savings purposes.

Compared with foreign countries the lack of fire-retardant conveyor belt

One, carrying capacity is poor, life is short. Of PVC, PVG flame retardant conveyor belt carrying capacity and life of most less developed countries to use the largest 1000S retardant Elevator conveyor, for example, the domestic life of the tape is generally not more than two years, the amount does not exceed the cumulative coal

More than 200 million tons, while the useful life of similar products abroad more than 4 years, the cumulative amount of more than 6 million tons coal.

Second, the lack of core technology, independent innovation ability is poor. Our PVC, PVG whole flame retardant fabric vertical conveyor manufacturers, mostly small and medium enterprises, and foreign produce PVC, PVG flame retardant conveyor belt manufacturers and more for the world famous enterprises, with strong core technology and independent

Innovation in the manufacture of the product while creating products, while most domestic companies manufacture products not only to create products.

Third, the process equipment and production technology level is not high, the lower grade of products. Domestic enterprises, flame-retardant PVC conveyor belt production technology is more mature, but PVG retardant conveyor belt production technology level is still low. The first is relatively backward and complex production processes, energy consumption,

Low productivity, and because the band body through the second plasticizing strength severely decreased. The most advanced production technology is the use of an extruder veneer molding process, eliminating the traditional production process of mixing, shaping, vulcanizing and other processes to achieve with a core leaching paste, plastic, covered

Cover stickers, vulcanized continuous production, the production efficiency greatly improved. At present, China's production of the highest strength grade PVC, PVG flame retardant conveyor is 2500N/mm, a maximum width of 2000mm, while foreign produce strength 4000N/mm, of a width exceeding 3500mm

Whole flame retardant fabric conveyor belt.

Conveyor Design Issues to be considered

Conveying the material ①: Under normal circumstances, to consider: the general characteristics of the material, density, maximum particle size and the like; special cases also

need to be considered: whether oil or chemicals, the maximum temperature of hot material, flame retardant demand;
② maximum carrying capacity or the maximum required transmission capacity;
③ Bandwidth;
④ belt speed;
Conveyor line ⑤ Setting: head along the industrial belt conveyor direction, the distance between the end of the drum; raised or lowered in height, or any upward or downward conveyor elevation

of the top and bottom sections; all up or down conveyor section inclination; all the vertical position of the curve and the radius;
⑥ Drive: single roll or double drum drive; the case of double-drum drive, the total power of the first motor and the second assignment on the drive roller; conveyor belt wrap

angle of the drive roller; drive device location; roller surface, glossy or plastic surface; adhesive surface type; using boot-shaped

Style;
⑦ Drum Diameter: Roller diameter material handling conveyor according to the actual requirements necessary to determine;
⑧ tensioning device: type, location, and tensioning stroke;
⑨ roller: Type, roller diameter, groove angle; idler spacing, including the head and tail length of the transition period;
⑩ feeding device Type: chute number; blocks expect free fall height of the conveyor; guide trough length; buffer roller or buffer frame without shock; feeding the angle between

the belt;
⑾ in cold climates, the expected minimum working temperature;
⑿ used conveyor Connector Type: vulcanized joints or mechanical joints;
⒀ adopted Belt Cleaner Type: vulcanized or mechanical type.

How to solve the problem of slippage

1 hammer belt Pipe conveyor tensioning using hammer slipping belt conveyor tensioning device can be added when the belt slipping counterweight to solve, added to the belt does

not slip up. But should not add too much so as not to be subjected to unnecessary excessive belt tension and reduce the lifetime of the belt

Life.
2 screw or hydraulic tensioning belt tensioning machine skidding or hydraulic tensioning screw using the industrial conveyor tensioning adjustable tensioning stroke when slipping to

increase tension. However, sometimes the tensioning stroke is insufficient, the permanent deformation of the belt occurs, then the belt can be a truncated heavy

New vulcanization.
3 In the EP is using nylon straps or tensioning required a longer trip, when the stroke is not enough can be re-vulcanized or increase tension trip to resolve.
4 tumbler plastic bag. Using diamond or herringbone rubber plate plastic bag or plastic bag with ceramic sheet for.

Why are prone to cracking off conveyor belt joint

Strength of the joints Flexible Roller Conveyor than the normal lower the strength. General mechanically connected, joint strength can only reach 40-50% with body strength, way better

quality cold glue, the joint strength can reach 60-70%, while the hot glue joint strength can reach 80-90% ( meet

Head right way, no quality defects). Since the strength of joints is relatively low, if the bonding method is not correct, joint strength will be more low, such as surgery,

injuries to the next level when sanding cloth, sanding over-lap length is not enough, the number of steps is not enough, glue joints The rubber sex

Can be poor or have lapsed since the sulfur, excessive grinding rope, wire rope rust, joints strength will be greatly reduced, when in use, disconnect joints prone to the

phenomenon.
   In addition, the Plastic belt conveyor belt if you do not use sealing compound, or glue joints in the wrong direction, the joints prone to cracking (surface plastic parts).

Whole flame retardant conveyor belt structure and working principle

The conveyor consists of three parts: a whole with a core, PVC impregnated paste coating.
Overall Belt conveyor belt is the skeleton of the core material. Reinforcing materials of high quality and high-strength polyester industrial filament yarn and nylon filament yarn,

woven into a B-type three or more the overall structure of the fiber structure compact and reasonable. Having a low elongation, high strength polyester industrial filament

ensure Conveyor

The low elongation process; weft yarn made of high strength nylon industrial ensure that the roller conveyor trough ability and impact resistance; cotton woven covering the whole

surface with a core, to increase the amount of absorption paste, to protect the core, ensure wear resistance and service life of the belt. Therefore, the use of such workers

The overall structure of woven arts with a core, in line conveyor applications require low elongation, good trough ability, better joint strength, tear resistance and abrasion

needs.
PVC plastisol is used to fill impregnated with a core. Each overall braid core performance required must be impregnated plastisol into high tensile plastics plastics boxes

stereotypes, their physical and mechanical properties have been strengthened to improve. PVC plastisol from a variety of different properties of chemical raw materials Complex

As to ensure the required safety belt, such as flame retardant and antistatic properties. Safety performance to ensure the safe use of conveyor belts, reduction of accidents,

absenteeism relief for the harm.
Overburden conveyor determines the transport properties, impact resistance, wear characteristics, corrosion resistance, it is through the formation of high-temperature plastics

or vulcanizing. There are two kinds of cover to choose from, plastic cover for transport angle less than 15 degrees in the environment; rubber cover for transport dumping

Angle less than 20 degrees in the environment, but it has better climbing ability, the greater the traffic, and greater wear resistance. Different rubber cover layer used in

different environments and conditions, our factory can produce different performance according to user requirements conveyor belt, there is wear resistant, oil-resistant,

complex

Combined type. Overburden greatly affect the life of the belt.

Pattern alkali conveyor belt maintenance

⒈ conveyor in the transport and storage, should be kept clean to avoid direct sunlight, rain and snow Baptist leaching, prevent acids, alkalis, oils, organic solvents and other

substances affecting the quality of rubber contact and one meter away from the heating device. ⒉ warehouse or storage temperature should be kept at -15 ℃ -

+40 ℃, relative humidity should be maintained between 50-80%. ⒊ in storage Belt conveyor must be placed, not folded, turning once during placement shall be on a quarterly

basis. ⒋ conveyor speed not more than 5.0 m / s, transport large blocks, abrasive materials and the use of a large fixed plow

Unloader device should maximize the use of low-speed. Beyond the prescribed speed, will affect the life of the tape. ⒌ pallet conveyor drive roller diameter and the relationship

between the fabric layers, supporting the drive roller bend pulley and idler groove angle on the requirements should be based on conveyor design requirements,

Reasonable selection. ⒍ material on the tape to reduce the impact and abrasion, feeding direction should shun the tape running direction; materials fall into the gap on the

tape should be minimized; mouth should avoid feeding roller or rollers just above; tape by material section should be shortened idler spacing and buffering measures taken

Shi. To prevent scratch tape, stop feeding device scraper cleaning device and unloading device and the contact portion of the tape should be appropriate hardness of the rubber

sheet, do not use fabric layer sandwiched tape head.

Overview of China's high-strength conveyor belt and Development

"Plan" period, China put high strength vertical conveyor of rubber industry as a priority. After twenty years of efforts, China has come a long high-strength belt development. At

present, China is a high-strength belt either product standards, production technology, process equipment,

Or product variety and quality are the main basic approach similar products with the developed countries. Some of the major companies in developed countries essentially

maintains the simultaneous development of the situation. It is reported that in 2006 China's output reached 153.57 million square meters bucket elevators, continues to rank first

in the world with an estimated strength

Force conveyor belt production accounted for about half. The intensity level, national standards or industry standards, steel cord conveyor belt up 5400N/mm, canvas laminated

core belt up 3150N/mm, the whole fabric conveyor belt up 3400N/mm.

Cold, acid and other special purpose conveyor belt, as well as tubular conveyor belt and a variety of special structure inclined conveyor belt. Basically made of high strength

conveyor belt not only can adapt to the needs of national economic development, every year there are some products exported to the United States, Germany, Britain, Italy,

Romania

Mani industry, Australia, Brazil, South Africa, Japan, South Korea, North Korea, Iraq, Southeast Asia, dozens of countries and regions.

How to improve the useful life of the conveyor belt

1 Improved conveyor hopper off. Improved drop hopper conveyor, conveyor belt is to prevent premature failure of one of effective measures. Improved transfer of the belt off at

the hopper, the capacity to increase by 2.5 times foreign, long, large foreign body in the transport process is not easy in the funnel wall and conveying the card

Belt, and reduces the probability of foreign torn belt.
Off the lead at the feed hopper skirt to match the Plastic belt conveyor running along the direction of the gap is growing, solving coal, stones stuck in between the belt and skirt the

issue, thus causing the belt to eliminate damage. Larger drop hopper baffle installed inside the buffer, to avoid material

The direct impact of material conveyor.
(2) adding at the bend pulley scraper device. Along the conveyor belt idler pulley at additional scraper device, eliminating the bend pulley bonding material at issue, address

the sticky roller conveyor local damage caused by the material.
3 delivery head, tail and intermediate reproduced at the transition improvements. Delivery head, tail and intermediate transition reproduced at length and transition, a great

impact on the service life of the conveyor belt. Subject to reasonable transition should be designed to minimize surface wear rubber conveyor belt, make sure there are no

Folding conveyor belt, the middle projection phenomenon, blanking material spill does not appear at.
4 conveyor at the transition in the concave pressure roller. Practice has proved insufficient transverse strength rope conveyor, startup, partial pressure belt pulley causing

excessive force, resulting in torn conveyor belt, change all the pinch roller pressure belt rollers, can solve this problem .
5 big machine boom conveyor counterweight load shedding. Coal yard stacker system initially life is very short conveyor boom, counterweight design overweight is caused by belt

tension is too large, an important reason for premature aging cracking. Carriage belt tension to meet the material, based on the weight reducing

After delivery of the 1.5 million t of coal extend the life of 450 million t. 200,000 t ore with the system conveyor stacker-reclaimer boom counterweight to the original design

25t (including counterweight roller weight), the original German imports tear wire with less than 3 million jobs a serious stretch t scrapped, after two times lower load

shedding

6t counterweight, the use of domestic ordinary steel band, the job amounted to over 800 million t.
6. Material flow direction adjustment. Material flow direction has an important impact on the life of the belt, the belt should make the material flow in the same direction to

run, can greatly improve the life of equipment.
7 local damage restoration techniques to extend belt life. (A) local thermal curing; that is, we often say that the heat of the need to be equipped conveyor belt vulcanizing

machine. (2) local cold splash, liquid products are Germany Dipu Te technical polymer composite restorative materials, etc., but left to be cured at room temperature 10h

Right; (3) local cold bonding, using repair section (vertical gap), T2 adhesive cold glue a longitudinal cracks fill plug (need special glue gun). Advantages of these two

methods is less manpower inputs, and has good resistance to abrasion and reinforcing properties, the recovery time is shorter, the disadvantage is the requirement for the

environment

High and can not be restored to the original flat belt surface requirements; (4) Telescopic belt conveyor spray repair techniques. The technology is several mixed liquid material by special

equipment, high pressure spray to a belt worn surface, according to need spraying certain thickness wear layer. Short curing time, for even into a film bureau

Ministry of wear, the effect is very good, the disadvantage is the need for a dedicated device.
8 reasonable choice belt type and maintenance. Reasonable choice type, depending on the season to adjust along the correction device, plus sunshield and winter maintenance

measures are also extended belt life.
9 other management issues. Strengthen management rollers and sweepers, damage must be promptly replaced. Control with load starts.

How to reduce the deviation phenomenon of belt conveyor

    Belt conveyor belt deviation runtime is the most common faults. To address such failures is important to note the dimensional accuracy of installation and daily maintenance.

There are several reasons for deviation, to be based on the difference between handling different reasons.

     1 Adjust the rubber belt conveyor idlers bearing belt in the middle of the entire belt conveyor idlers deviation, adjust the position to adjust the deviation; idlers in the

manufacture of both sides of the mounting holes are worked into holes in order to adjust . The specific method is biased which side of the belt, roller

Group toward which side of the belt forward direction forward, backward, or the other side. Belt upward direction of deviation is lower roller group should be at the left, the

upper roller group moved to the right place.

     2 Install the self-aligning roller group aligning roller group has a variety of types, such as intermediate shaft type, four-link, vertical roller, etc., the principle is

the use of block or roller rotates in the direction in the horizontal plane lateral thrust block or generate the Automatic belt adjustment belt deviation reaches to the heart of

the purpose. General

The total length of the belt conveyor belt conveyor shorter or bidirectional operation using this method is more reasonable, because the shorter belt conveyor easier deviation

and not easy to adjust. And long Incline Belt conveyor is best not to use this method because the group aligning roller belt use would make

Useful life of a certain impact.

     3 Adjust the drive pulley and the driven pulley and bend pulley position adjustment bend pulley belt deviation adjustment is an important part. Because at least a belt

conveyor rollers 2 to 5, the installation location of all rollers of the belt conveyor must be perpendicular to the longitudinal direction of the center line,

If the skew is too large deviation bound to happen. Adjustment Method and its group of similar idlers. For the head drum as the drum belt deviation to the right, the right of

the bearing should be moved forward, the belt deviation to the left of the drum, the left bearing housing should be moved forward, also the corresponding

You can move left or right rear bearing housings after the shift. Rear roller adjustment method and the head drum opposite. After repeated adjustments until the belt transferred

to an ideal location. Adjust the drive or bend pulley in the best pre-install its exact location.

Conveyor belt transmission principle characteristics

⑴ traction belt conveyor drive roller and the belt by friction between transitive, so must the tape taut with tension device, so that the tape at the transfer cylinder drum

separator has a certain initial tension.
⑵ tape together with cargo runs on rollers. Tape both traction, but also a host agency, cargo and no relative motion between the tape, eliminating tape and cargo loading

operation of the frictional resistance. As built with roller bearings, tape and rolling friction between the roller, because

This
Running resistance greatly reduced, thereby reducing power consumption, increasing the transport distance. For a conveyor belt, the size of the traction transmission capacity is

determined by the tension of the tape, the tape around the drive roller and the belt wrap angle and the coefficient of friction between the drive roller. Wish

Insurance
Certificate Belt conveyor belt does not slip on the drive roller, running, in the production practice according to different situations to take corresponding measures. Improve

traction transmission capacity available from the following aspects:
⑴ increasing tension force (initial tension). Conveyor belt in operation, the tape to stretch, resulting in traction lowered, according to the situation, the use of the tape

tensioning device suitably taut, the tape tension increases, to increase traction.
⑵ increase the coefficient of friction. The specific measures are: to protect the drive roller is covered with a wooden or rubber gasket lining to increase the coefficient of

friction, on the other hand less water coal, preventing friction coefficient decreases.
⑶ increase around corners. Underground Flat belt conveyor as poor working conditions, the required traction, so use double drum drive, in order to increase around corners.

Belt conveyor belt conveyor is the abbreviation

Large angle belt conveyors in the coal industry in the application

   Large angle belt conveyor can be widely used in coal, food, building materials, chemicals, utilities and metallurgical sectors, at an ambient temperature of -19 ℃ ~ +40 ℃

range, conveying bulk specific gravity of the various 0.5-2.5t/m3 bulk materials, sidewall conveyor transmission angle range of 0 ° -90 °

, The maximum particle size of the vertical transport of materials 400mm. There are special requirements for the transportation of materials, such as high temperature, with

acid, alkaline, or organic solvents, oils and other ingredients of the material requires the use of special sidewall conveyor belt, is currently in the coal industry to promote

the use was the most effective.
Inclined belt conveyor Telescopic belt conveyor with ordinary simple structure, reliable operation, easy maintenance, etc., in addition to having more inclined (90 degrees vertical)

transmission, compact structure, small footprint, and other characteristics, so it is inclined (or vertical) conveying the ideal equipment. Through years of not

Unremitting efforts to continuously upgrade inclined belt conveyor height (maximum reached 203m), to expand transmission capacity (maximum reached 6000t / h), in underground

mining engineering, open pit mining, large-scale self-unloading peers and have adopted and produced good economic benefits. Ribs with by the baseband, ribs

And a separator composed of baseband appearance with ordinary conveyor belt, but greater lateral stiffness: wavy ribs was: ugly plate can be divided into sections according to

their different T-, C-and TC type. T-apply inclination β ≤ 40 ° occasions, C type for inclination β> 40 ° and the material better mobility of the occasion,

TC type for inclination β> 40 °, viscous material, the viscosity of the occasion.
Its main features are: large transmission angle up to 90 °, is steep conveyor and vertical lifting the ideal equipment. So you can save floor space savings in equipment

investment and construction costs, and achieved good overall economic efficiency. For example, a user wishing to upgrade to 20m high coal feed

Warehouse roof, such as using wall machine at 45 ° transmission angle, the captain only 28.3m (horizontal captain 20m); And if the wall vertical conveyor machine, then the

captain can be controlled at the level of less than 6m; structure Simple, all major components are common with ordinary belt conveyor, please use

Maintenance convenience; reliable operation, no buried scraper conveyor chain recurrent cards, floating chain scission phenomena and bucket elevators often happens slipping away

fighting the phenomenon. Its reliability is almost equal with the usual conveyor; smooth running, low noise; since there is no loading

Material when digging resistance and runtime internal friction material, external friction, therefore energy consumption. For example, in a coal mine to use each of the two

lifting height 19.28m, each conveying capacity 25t / h vertical ribs crushed coal conveying machine, each of the installed power is only 4kW, be they

Replaced by the four original buried Conveyor System total installed power of 44kW.
Vertical wall machine can also be set up in the nose and tail sections of arbitrary length horizontal transport, and other equipment to facilitate convergence.
No scattering material, flexible layout, the models with the ordinary conveyor, bucket elevator, scraper conveyor comparison, the comprehensive technical performance are

superior.
Inclined belt conveyor through ten years of promoting the use of, is now increasingly recognized by all coal companies and love, at the national regulation of small coal mines,

the coal industry to promote the development of a large group of integration policy context, the inclination to adapt large-scale development, in line with national

Home industrial policies, I believe that through mechanical manufacturing technology innovation progress, from materials, organization, design aspects of continuous improvement,

the large angle belt conveyor industries in China will be more widely used, for national construction and development of more good role.

On China's development prospects belt

        Heat resistant Belt conveyor is made up of layers of rubber covered with cotton canvas upper and lower temperature or heat-resistant rubber, high temperature

vulcanization bonded together, suitable for handling 175 degrees Celsius heat coke, cement, slag and hot castings, with good wear resistance.
High temperature resistant conveyor belt production specifications are different from ordinary. The conveyor belt manufacturer in 2011 launched a unique heat resistant conveyor

belt. Heat resistant Flexible Roller Conveyor is mainly used in metallurgy, construction and other industries, transportation sinter, coke, cement clinker and other high-temperature

materials, and material

Material temperature does not exceed 800 ℃, with a surface temperature does not exceed 220 ℃ the conditions of use.

Transport machinery and equipment and automatic integration development

     After joining the WTO, China's economic integration into the world economy, accelerate the pace of industrial restructuring policy, so that our country quickly became the

world's processing manufacturing country. With the influx of foreign-funded enterprises, China has become an important base for processing and manufacturing one. Requires a lot

of Airport conveyor Mechanical engineering and automation professional application of advanced engineering and technical personnel, especially in conveying both the use of computer-aided design of

mechanical products, but also the application of CNC technology for manufacture of talent is very scarce, the job market has broad prospects.
Mainly to the industrial production of the first line in the transportation equipment manufacturing in the field of mechanical design and manufacturing, technology development,

applied research, operational management and sales and other aspects of the work. As the importance of conveying equipment machinery industry and a huge scale, you need a huge

professional people

Only team. For some time, transportation machinery will have greater demand for talent. NC has the ability to develop talent competition for all enterprises will become the

goal, transport machinery design and manufacturing and processing professionals in recent years, supply and demand ratio is also high. From the perspective of the development

industry, transportation machinery, transportation

Send machinery, upgrading machinery, assembly line equipment, Conveyor System engineering machinery and other heavy head product outlook remains optimistic that the industry will be

further automated electromechanical optoelectronic integrated development.

Transportation equipment and optimization of logistics and distribution conflicts

Transportation equipment line is the object of labor in accordance with certain routings, sequentially through each work center and according to certain production speed (tempo)

to complete the job continuously repeated production of a production organization. Unidirectional transport equipment lines, continuity, specialization,

Balance and dominant characteristics, its flexible conveyor logistics operations must obey and serve the needs of the production process, interwoven in the production process

around the core, so the plant has a strong tie logistics, dynamics, distribution and balance, and with this feature while

Production environment, conditions, market, product type, processing technology changed, re-optimize and balance.

First, the logistics pipeline transportation industrial belt conveyor contradiction

Transportation equipment production line features high-efficiency production and inefficient, complicated logistics, plant logistics constraints become a bottleneck

unobstructed. If a production logistics enterprises in the process of transformation of the existence of the following questions.

(1) logistics containers have a preliminary standardization, but the use of the container is still no standard packaging not really realize standardization, stacking remained

clutter.

(2) Premenstrual transformation smoothly throughout the logistics online, but the operation was not only at the appropriate time distribution appropriate quantity and quality of

material goods to the right place, there is still a slight margin, resulting in the accumulation of material I increased, stacking online body side, still affect the follow-up

materials

Distribution, cut-off phenomenon is still generated.

(3) bulky and heavy weight different types of products, resulting in low efficiency of labor, product assembly quality degradation; same time, depending on the product line on

equipment utilization greatly reduced, a device or an online procedure once a fault, so stop a vicious

Circulation, thus affecting the operation of the entire production line, so that the reliability of production lines greatly reduced.

(4) The original production line is set with strong rigidity, poor adaptability of the product structure, when converting, the production line of the material on the lower level

compared hectic, because online workers each work center has been set, this aspect of the workers labored handling (especially

Bulky) affecting production; hand and often leads to materials not on the on the under no under item confusion, so that production almost paralyzed transportation equipment

operation.
