Four technical parameters of the conveyor

    In the daily production process, we will according to the requirements of material handling systems , material handling sites of various conditions , characteristics related

to the production process and Incline Belt conveyor materials to choose what type of conveyor, we introduce you to the following for delivery four technical machine parameters

Number :
A conveying capacity : conveying capacity of the conveyor is the amount of material fed per unit time . In the transportation of bulk materials , quality or volume of material

transported per hour is Flat belt conveyor calculated ; conveying items into when to calculate the number of pieces delivered per hour .
Second, component size : the size of the conveyor components including conveyor width , slat width , hopper volume , pipe diameter and vessel size. These components have a

direct impact on the size of transmission capacity conveyor.
Third, the transmission speed: increase transmission speed can increase transmission capacity . When the conveyor belt for traction to transport large pieces and length of the

growing transport speed increases . But high-speed operation of the belt conveyor to note vibration, noise and start braking problems. As for pulling parts with chain

Conveyor , conveyor speed is not too large , in order to prevent increased power load. Simultaneous operation of conveyor technology , transmission speed should be required to

determine the production process .
Fourth, the feed length and inclination : the length and inclination of the transfer line direct effect on the total resistance of the conveyor and the power required .
        These are the four main technical parameters of the conveyor , and I hope in the process of selecting conveyor , helpful.

BLT -type scales conveyor structure advantages such as Introduction

Design of the product and its advantages

other components.
( 1 ) scales board device
Scales shown in Figure 1 90 degree turn conveyor is a carrier member board device and pull the bow conveyor parts, its tank in direct contact with the material , to be able to withstand heavy impact

with steel stamping into a wavy bottom with ribs , with triangular studs reinforcing ribs, so as to have sufficient strength and rigidity. Traction chain 2

For the two 90 degree conveyor bush roller chain , directly exposed to traction. Left and right angle bracket by pulling the chain are connected with 4 1 tank , the tank on both sides of each

section separately fixed a walk round three , walking round with double rolling bearing .
( 2 ) drive means
YJ minute drive YX or type two ( see Figure a, 2b). YX -type drive by the Y series motor 1 , 2 and XEW triangular pulley vice planetary cycloid reducer three components. YJ -

drive device consists of a Y series motor , triangular pulley 2 and vice JZQ reducer 4 components.
( 3 ) tail wheel tensioning device
The chain tensioning means comprises two tail , a long axis and a pair of tension through the screw components. Each rear sprocket are twin scroll
Bearing a tail on the same axle .
Advantages (4) BLT type plate conveyor scales
① walking round slat device built double bearing, low running resistance. As plate width is 1000mm B with old scales board machine , walking wheel diameter D = 180mm, try

running side drag coefficient is 0.13 . BLT series of walking round diameter D = 110mm, testing the drag coefficient is 0.03 .

Run the drag coefficient is reduced by 75 %.
② left and right traction chain and bolted tank , do not use common through shaft , reduce weight . For example plate width B = 800mm, P = 315mm chain link conveyor scales ,

can save steel 30Kg / m. Since the left and right through the shaft without traction chain associated , respectively, with a double tail two sprockets

A rolling bearing fixed on the shaft , a traction chain is only S / 2. S is the total traction. A connection form of the original chain traction should be considered 75% -80 %

of the coefficient of unbalance , the actual traction chain BLT series connection form than the original 20% -25 % .
③ scales board tank made of sheet steel wavy structure , thickness is thinner, use the triangle strengthening ribs and angle , so that the tank light weight, rigidity and

impact resistance. For example, the same as B = 1000mm scales board, old scales board weight is 324Kg / m, while the BLT -type scales board only 175Kg / m, saving

Steel, but also reduces the daily energy consumption .
④ walking round with traction chain arranged separately , easy installation and maintenance scales plate device.
⑤ reducer ratio YX driving device , output shaft allowable torque, it directly through the Oldham coupling with
Head axle joints, the head wheel device and configuration of the entire drive system performance greatly simplified , low cost, easy to install.
⑥ tail wheel tensioner two double sprockets are supported by the end of the axle rolling bearing , not only can reduce the resistance of the drag chain to bypass the rear

sprocket , and two traction chain when not synchronized , the chain can be adjusted automatically .
BLT -type scales conveyor for conveying bulk materials chunks or burning , its structure is characterized by a steel stamping into the tank bottom with wavy wall , there is

sufficient strength and stiffness , traction chain and tank bolt connection , light weight .
The products have been widely used in casting , building materials, mining, paper and other industries, which have been used in the product slat width of most dogs 2400mm,

maximum conveyor length L = 100m, climb a maximum height of 10m. Use of proven , BLT -type conveyor scales reasonable structure, advanced performance. Next

A brief description of its surface structure , the main parameters .
Use BLT type plate conveyor scales
BLT -type scale is a special conveyor slat conveyor , can be used as stationary mechanized transport equipment , transporting heavy bulk material or a single member , in

particular for conveying hot materials chunks or facilitate the transport of material in the process completion of cooling , thousands of dry, heating , cleaning and

Classification processes. Transport can be tilted up or down , in the machinery , chemicals , building materials, metallurgy , power , and mining and other industrial sectors

have broad applicability.

The belt conveyor means working resistance decreases

Belt conveyor running process will be affected by many factors , belt conveyors drag coefficient , what is it ? Following is a brief for introduction:
1, the roller conveyor running resistance coefficient
Running resistance coefficient measurement principle : the use of belt conveyor load operation of the motor input power was measured. Measured motor power, calculated shaft

power ( if they can measure plastic chain conveyor the efficiency of the motor , speed reducer efficiency and coupling efficiency , the calculated value of accurate , on-site generally

Accordance with the experience value ) according to shaft power , traction and running resistance of the relationship , you can calculate the running resistance coefficient .
2 , reducing belt conveyor means working resistance
That the use of high precision and high performance tape roller tends to reduce conveyor working resistance . Roller conveyor forward rotation resistance and resistance

accounted for belt conveyor major resistance 50 ... % 80m belt conveyor captain beyond the formula for calculating the total resistance , total resistance to attacks such as by

Conveyor according to the length of the selected charge coefficient , and conditions of work with the device associated analog friction coefficient , conveyor length , carrying

branches roller rotates local mass per unit length , the return branch of rotating rollers local mass per unit length of the conveyor belt unit mass , transport of materials

Unit mass ( with belt conveyor conveying capacity , material bulk density and tape speed related ) special friction roller forward main drag and friction tape cleaner special

additional parameters such as impact resistance .
We all want the machine to play the biggest role , then you should try to use the appropriate method of narrowing the drag coefficient , the belt conveyor efficiency reaches a

maximum .

New railway construction integration role and soil mixing conveyor belt use

Living house dust and noise away from the spirit of the principle of mixing station located at the rear . After the completion of the layout of the site hardening mixing station

, laying the concrete layer and gravel cushion 10cm thick. Concrete mixing station layout three centralized selection of equipment supporting concrete

Soil mixing station mainly concentrated Equipment Name Model Number Capacity and specifications compulsory mixer JS50025m3/h2 batching machine HPW800D50m3/h2 computer controller

SLZK42 loaders ZL30A1 concrete pump truck drag chain conveyor concrete mixer truck Metropolis Metropolis IHI20m3/h1 cards 6m33

Generators 120kW14 mixing plant designed by two sets consisting of mixing floor pavers common arrangement mostly single or dual -column . Namely the so-called single-row

opposite type, the discharge port disposed roller conveyor in the middle, two sides of blender breakdown ; namely the so-called double -row side by side , two juxtaposed mixer

The discharge port are moving in one direction . Advantages of single -type concrete the material quickly , the overall stability, security and good ; drawback is you must

follow the mixer batching machine breakdown on both sides of the mouth feeding , stacking and loading of concentration, loaders must charge back and forth on both sides . Double

-row compact appearance with

Feeder two in a row, side by side on the material , loading concentration, and small footprint . Drawback is controlled by batching machine pitch , resulting in two sets mixing

machine spacing is too large, resulting in the discharge port connected hopper slope too slow , difficult to discharge , recurrent obstruction affecting production. According to

my unit volume of concrete and pipe work

The actual situation of tight , we chose the single -style layout .
Concrete production , transportation and pumping concrete pumping sand pipe production of concrete production is mainly carried out through the concrete mixing , and its

production process is semi-automatic , automatic control computer that batching , mixing manually controlled discharge , specific production process is divided into feed

, Metering , mixing , discharging four stages .
( A ) feed materials from the stockyard by a shovel loaders transported to breakdown on both sides of the mixer batching machine hopper . Hopper as one of the three- hopper

structure , a stone warehouse, two sand compartment.
( 2 ) Measurement of Aggregate measurement through batching machine computer controller automatically , portable weighing vehicles metering , simply enter the preset mixing

ratio can be automatically measured . Measured in pounds , said cement , artificial unpacking ; admixture add custom containers ; water metering using automated quantitative

water

Sheets to control .
( 3 ) mixing cement , gravel , sand by the lifting hopper raised to the mixer fully mixing , and controls water . Mixing using timing control , compulsory mixing . Optimal

mixing time required by field testing to determine , on-site control by not less than 45s .
( 4 ) adequate mixing of the raw material discharge port after falling to a tanker inside . The hopper can be made , the opening size and tanker inlet matches while ensuring a

smooth interior , slope can not be too slow , so as not to affect the flow rate of the concrete .
Concrete transport refers to transport concrete from the concrete mixing station pumping from the tankers to the scene of the process. Tanker loading excluded before the water

inside the drum . In the process of feeding and transport to gyrate , to prevent segregation of concrete . After access to the site , let Drum Forward

12min and then invert the material. After unloading tankers with self- hosed spout and chute concrete residue adhering to avoid affecting the next concrete discharge flow rate.

In the summer the temperature is high ( greater than 25e), pay attention to controlling the lifetime of the concrete in the tank does not exceed 1h. Cool

Summer season can be wrapped canvas tank to minimize the influence of ambient temperature on the slump .
The transport conveying concrete using concrete pumping main tank to send complementary approach. For bridge piers and other structures to pumping with higher strings pouring

cylinder method ; foundation for culverts and other structures in the lower tank Entitlement to chute pouring method . Construction should pay attention to the following parties

Face: ( a ) pumping grading requirements for raw materials is high, as can be required before mixing pump test. Reasonable mix and well-graded aggregate is an important factor

to prevent plugging . ( 2 ) before you start pumping water into the wet hopper and pipe , and then pressed into 1B2 cement mortar to lubricate the tube

Road, the concrete in the pipeline to increase mobility . General mixing two materials ( approximately 1m3) can be. ( 3 ) of the pumping site , the concrete tank due to the drop

height and the slump of the concrete , the concrete flow or poor often accumulate in the pump inlet grid made ​​of steel

Feed into the slow , dedicated two people can carry on a shovel from the tanker to the concrete chute down Pa , the accumulation of concrete paving on the grid to open .
Experience ( 1 ) through the establishment of centralized Qinshen line mixing station , concrete immediate focus was on the concrete mixing quality and the role of the

construction progress . First, the purchase of materials and the main timber unified , stable quality , which will help manage and reduce material waste ; Second , measuring

quasi-

Indeed, mixing speed, high quality concrete , reducing human factors on the quality of the concrete ; Third , equipment centralized management , maintenance and timely ; Fourth,

mixing station factory construction, construction procedures , skilled workers to operate , less prone to accidents. ( 2 ) Concrete concentrated

Mixing various projects currently stand construction has obviously demonstrated its superiority , but into a larger one , the ministry only mixing plant mixing station ,

batching machine, truck and tanker reached 4.4 million yuan investment . In order to save investment , conditions can be self-processing part of the equipment , such as batching

machine , storage

Hopper , purchasing some electronic component assembly can also achieve the same effect. Mixing machine during use , liner, leaves a large amount of wear and tear , replacing

more frequently, and expensive, belt conveyors can be customized to a specific mechanical machining or processing plant , the cost can be reduced about 70%.

Conveyor belt industry focus on issues

Although the current domestic shipping companies with the skills and product quality in order to have a qualitative progress, some companies can also be produced in a variety of

national and international norms fabric Incline Belt conveyor core and steel cord conveyor belt , and its product quality has been recognized by the international high-end users , but also points

conveyor belts career save

Concern the following issues :

      First, is the choice of international norms progress . In recent years , China's export volume of belt conveyor is growing, do not accept the Chinese foreign general

specification of the product, pleading use ISO, Germany or the United States and other specifications. Thus, the conveyor belt enterprises must collect , digest relevant

international norms, and Weight Sorter press

Foreign skills specifications produced production, inspection, packaging and services.


      Second, is to strengthen the special conveyor belt of discussion. To continue to add product product quality standard types and progress , strengthen high temperature

conveyor belt , cold conveyor belt , pipe conveyor belt , conveyor belt ripstop , high wear-resistant conveyor belt , ST5000 more high-strength steel wire rope conveyor belt

development

. As for transporting highly abrasive materials habit , progressive conveyor belt using life abroad than in Germany has developed a standardized surface abrasion rubber

materials, wear reaches 50 to 70 mm3 .

      Third, is the development of energy-efficient low-drag conveyor belt . Current foreign countries have developed a low running resistance energy-saving conveyor belt and

transported over long distances on the use of machines , general conveyor belt operation drag coefficient from 0.02 to 0.025 , while the energy-saving conveyor belt at 0.016 or

so , you can cut operating

Energy consumption about 25%. It is understood that the newly developed Goodyear Easyrider conveyor belt is through changes in recipes to make conveyor belt down like tire

rolling resistance , like , a year can save 12% power consumption, save energy and help the user .

      Fourth, the problem is the conveyor belt safety factor . Factory in the selection of current delivery wire conveyor belt , the domestic product safety factor of 7 to 9 ,

and in foreign countries is about 5, under the same conditions with the type of domestic transport higher than abroad 1 to 2 standard , add the equipment

Money and run energy , but also affect the product on the international market competitiveness declined conveyor belt safety factor is the key to progress conveyor belt joint

power and reliability.

Roller conveyor cleaning procedures

      roller conveyor There are two basic types , sub- driven roller and the drive roller two kinds , digital printers, transportation equipment , paper and packaging machinery and other kinds of drive transmission system can be seen everywhere , conveyor mainly carbon roller roller, power roller , stainless steel

Steel roller , PVC roller , these rollers are generally made ??of seamless steel pipe , of course , depending on the process needs, the materials used are not the same , for example, some will use 304L/316L stainless steel roller , 2205 stainless steel, aluminum 6061T5 so . Conveyor roller

Integral part of the production process have interference shaft assembly welding , fine cars and fine balancing school , roller body early cars, early school static equilibrium . After finishing needs of cylindrical grinder or roll grinder grinding , it is in tolerance for acts such as roundness, cylindricity and straightness and other requirements in the case of 0.2mm or less

If the hardness of the surface when required , then there is need to increase the heat treatment step , in order to rust and corrosion , wear and the support , after the roll forming , but also surface treatment or coating and oxidation processes. vertical conveyor to classify it according to the size of such a large paper machine

Armed with a roller, while small, such as automated assembly line on the use of flat belt conveyor idlers , in addition to the dimensions of the role can also be divided as to the accuracy of guaranteed delivery , such as digital laser printers on the roller, but also there have effect from the filter press calender rolls , in addition to right

Size less precision support idlers and heat exchange requirements rollers , etc., are numerous.
Understanding of the characteristics of conveyor rollers , the next we can understand the next conveyor roller cleaning procedures , and a detailed , practical and clean-up procedures are the following seven steps. In cleaning the rolls , it must be dedicated to the people to operate

And you want to wear gloves and anti- dust masks. Professional cleanup crews in the car before the first inspection conveyor equipment operation for unusual circumstances, such as fasteners are not loose and so on. Before loading items , use a pin fixed roller, avoid loaded items when rotated from

The safety of life severely affected . After casting roll barreled good , we want to cover the cylinder cover , and fastened with bolts , before cleaning , first open the ventilation equipment division , and finally opening roller, casting another unloading time , we should go to the roller cover positive direction , aided by

After the fixed bolt , then open the cylinder cover cylinder cover. During the operation of the roll , personnel do not close , the operation of the roller ban put around things like casting . In the roller conveyor shot blasting is not completely stopped rotating impeller before , do remember not to open the cylinder cover .

Chain conveyor features

    The main function of chain conveyor conveyor components are due to the structure of the chain can be ever-changing, so the chain Conveyor System is characterized by : chain

conveyor functions for many application environments and numerous requirements.
    1, the transmission diversity article
Chain conveyor can transport almost all types of items: large items and small items , small as a few grams of electronic components, large shipments to several tons can be used

to transport chain .
    2, the harsh environmental adaptability transport
gravity conveyor almost in a variety of harsh environment to work , that is, low temperature cold storage, high-temperature drying lines, rude loading forest, dusty cement plant ,

and equipment can be used coating line chain conveyor .
    3 , the arbitrariness of the flow of goods transported
Not only can achieve horizontal, vertical and inclined conveyor , but also according to the factory environment conditions , and do not need multi-unit , you can do undulating

circuitous transport ; Not only can achieve linear transmission, but also can be used for an endless conveyor , allowing the flow of goods transported has the greatest

arbitrariness .

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.

Belt width up to 3000mm, wide belt canvas laminated cores up 4200mm. In addition, domestic conveyor belt speed up to 5.8m / s, throughput of up to 8400t / h. In variety, not

only the high-strength general purpose conveyor belt, as well as fire-retardant conveyor belt, heat resistance,

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.

Belt conveyor belt conveyor is the abbreviation

Belt conveyor belt conveyor is the abbreviation of the conveyor belt using continuous or intermittent motion to transport all kinds of goods of different severity, can transport

all kinds of bulk material, but also transport all kinds of cartons, bags and other single piece weighing not large pieces of cargo, and versatile.
Conveyor belt material: rubber, silicone, PVC, PU and other materials, except for the normal delivery of materials, but also to meet the oil, corrosion resistance, anti-static

materials have special requirements such as the delivery. Using a dedicated food grade conveyor belt, can meet the food, pharmaceutical, daily chemical

Workers and other industry requirements.
Belt conveyor structure in the form: Groove Belt conveyor, flat belt conveyor, climbing belt conveyor, belt curves, telescopic belt conveyor and other forms, the conveyor belt

can be added to enhance the baffles, skirts and other accessories, to meet various process requirements. Conveyor with side table, retrofitting lighthouse

, As an electronic instrument assembly, food packaging and other belt conveyor assembly line.
Belt drive are: gear motor drive, electric drum driven.
Belt conveyor speed control modes: frequency control, infinitely variable.
Belt rack material: carbon steel, stainless steel, aluminum.
Applications: light industry, electronics, food, chemicals, wood, metal, mining, machinery and other industries
Belt Conveyor Features: belt conveyor stationary, materials and Conveyor System no relative motion, to avoid damage on the material to be transported. Less noise, suitable for the work

environment requires relatively quiet occasion. Simple structure, easy to maintain. Low energy consumption, low cost.

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.

Screw conveyor arrangement

Usually driven by screw machine, the first part, an intermediate portion of some of the standard, the middle part matches the command shell and supporting form.In except the end

portion of the first part, the casing and each section interchangeable screw conveyor, the end of the Qing screw feeding device of materials, installation, pay attention

location.Drive consists of a planetary cycloid motor (or other gear motor) commitments, and thrust bearings installed in the holiday first mobile phone, when the material is

transported to the axial force from the suspension and chassis bearing and the first part of basic equipment generated an intermediate portion of each security

Points have been used to support the propeller shaft bearing hanging, hanging bearings with radial ball bearings (or the entire bearing) at the end, with the scroll's holiday

(sliding) bearings to support and more helical screw shaft length error, install should start from the head, order. Screw (Spiral

Conveyor manufacturers, Elevator conveyor parameter) must be installed conveyor installation accuracy in good condition or not, is one of the prerequisites for everyday use, the use of

location technologies installed must meet the following requirements: If installed on the basis of the screw conveyor at least 10 days before the official end

Installation and water into the foundation should be able to reliably transport and support to ensure that the Foundation is not too small, because the screw hangars and other

changes to ensure that occur when operating the machine curve conveyor screw stability.When enough to hang in the dust Here, from the top of the spiral gray powder

Dust outlet conveyor bottom, left, and right will be.

Conveyor system analysis and design of the basic steps

Basic analysis of system design
The basic system design analysis include the following: to establish the system design goals, set the volume of transportation of materials, transport distance, material

processing methods, and to consider the future development requirements; collection of data about the material being transported, including fragmentation, bulk density and other

factors affecting treatment

Methods of characterization data; research available both inside and outside the factory floor space, attention may affect the types of roller conveyor systems or equipment

specification limit; study other site conditions and data: climatic conditions and public transport modes (rail, road and water transport, etc.); research plant energy, like

Compressed air, electricity, steam and gas and other supplies; research on past experience or a similar design system data; examine whether the material is sent to the

manufacturer's laboratory to test the necessity (for example pneumatic conveying system to carry the new material ).

The main steps of engineering design
From the above described method for engineering design can understand the concept of bulk solid material handling system design and analysis procedures should be designed. In

recent years, due to energy issues and the industry continues to progress, many engineering design company added a bulk solid materials transportation engineering

Department, the use of highly experienced engineers and technicians responsible for the whole system design work. Choose the world's most advanced technology and equipment,

industrial belt conveyor system design for a reasonable arrangement; selection of equipment meet the stringent requirements; rational use of space not only the area, but also

To control investment and shorten the construction cycle. To achieve these objectives, the design phase must have reasonable working procedures, as well as cooperation with

other sectors.
During the design before work, should be equipped with all the necessary information. First, according to material properties and the process parameters to study the transport

methods, routes and throughput, storage methods and storage, raw material input and product output mode, and to consider the type of transportation and storage equipment, etc.

And so on. Meanwhile, the reference to the relevant standards and site conditions, such as the buyer's specifications to check the system design and equipment selection has

affected or omissions.
According to the above considerations and research engineer responsible for the design of various factors and parameters can be summarized to conduct feasibility studies,

technical and economic comparison. After assessment, preliminary design.
In the preliminary design process for the system equipment selection and equipment data specified by the manufacturer should pay particular attention to the selected device

performance To learn more, others such as ordering the case, delivery date, equipment investment and the impact of design on other sectors . If the device support structure

Or foundation problems, pollution or dust problems, operational control of the complex and so on, until harmonization so far. In the initial design process, to negotiate with

the seller repeatedly research, control the investment under the premise of constantly modify the design, until both sides are satisfied. Then

Preliminary design cost estimate. Including equipment installed capacity is estimated as well as other indirect costs required. A detailed description of the preparation of the

system.
After the above steps, from initial design to enter the detailed design stage. Detailed design has the following main tasks: engineering flowchart; equipment specifications;

Equipment List; system specification; system floorplan; equipment capacity table; cost estimates table; said operation control system

Ming.
These data will be sent to the relevant departments as other professional engineering design basis and reference, such as civil, electrical, instrument control, and equipment

design department, while the purchasing department in cooperation with the inquiry, procurement and other work. After completion of inquiry, post purchase inspection department.

Inquiry

You can preselect several (usually four to five selection is limited) company at the same time, and ultimately to the best person for the selection of objects, submit the buyer

and the competent department for approval.
