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 .

Install belt conveyor belt right steps

Whether replacing belt , or in a new drive to reinstall the belt , North camel recommend the following steps .
1 , turn off the power , drag chain conveyor remove the discharge guard , spin Song Mada mounting bolts. Move the motor to make enough slack belt without removing the belt can be forced open . Do

not pry off the conveyor belt !
2 , remove the old belt and check whether there is abnormal wear. Excessive wear may mean transmission on the design or maintenance problems .
3 , select the appropriate conveyor belt replaced.
4 , clean the roller chain conveyor conveyor belt and pulley , you should cloth stained with a little less volatile liquids wipe soaked in detergent or use a detergent scrub belts are undesirable ;

to remove oil and dirt , wipe with sandpaper or a sharp scraping objects , apparently also undesirable. Conveyor

The installation must be kept dry before use .
5, check whether there is abnormal wear and pulleys are in a straight line symmetry. A straight line symmetrical to the conveyor pulley drive operation is essential.
6 , check the other transmission parts, such as bearings and sleeve symmetry , durability, lubrication and so on.
7, in the installation of new conveyor pulleys , do not pry or excessive force.
8 , tighten the gear center distance until the tension belt tension measuring instrument properly measured so far. Hand turn laps driving wheel , retest tension .
9 Tighten motor mounting bolts to correct torque. Since turning device during operation center distance will result in any changes in conveyor poor performance , it is important

to ensure that all parts are tight turning device .
10 , although no longer need to adjust the belt tension , we still recommend starting device and observe the conveyor performance , to see whether there is abnormal vibration ,

listen for unusual noises. It is best to turn off the machine , check the bearings and motor status ; if feels too hot , it may be transported

Belt too tight , or bearing asymmetry, or incorrect lubrication .

institutions . Bottom two rubber belt conveyor tapes from the rack-mounted rotating roller support. Upper section contains the shipping tape or re- working segment segment called by the trough

roller support, in order to increase carrying off the area, improve the transport capacity ; following paragraph tape is not called back to the empty cargo ship segment ,

commonly used plastic chain conveyor flat-shaped roller support. The role of the tape tensioning device is required for the proper functioning of the tensioning force provided .
    Belt conveyor working principle is : the motor -driven drive rollers rotate through active friction between the roller and the tape on the tape drive and tape goods with

continuous operation, when the goods carried to the end , due to the commutation of the tape and unloading, use of specialized devices can also uninstall any location in the

middle uninstall .

Nonstandard shaker general specifications and materials

   Currently vibration screening is a good variety , such as vibrating screen , vibration sieve , ultrasonic vibrating screen etc. , but many customers do not understand what is

non-standard sieve hot water heat exchanger shaker and what is non-standard specifications .
   Non-standard sieve shaker is one, is the scene of the large size of the material ( such as ore or each section of the crusher product ) for particle size analysis , and self

-made sieve set , it does not have a certain standard, mesh requirements are not too strict , the addition of manual operation , so called non-standard sieve or hand sieve. The

particle size of belt conveyor design the material is greater than 6mm . Sieve size determined according to need . Generally 150,120,100,80,70,50,25,12,8,6,3 mm , etc., because it is not common,

there is no uniform mesh size regulations, sieve size varies according to each site needs to manufacture .
  Non-standard sieve plate punching or wire mesh can be woven . Sieve analysis method is to use a sieve material a sieve for screening of different sizes , the material is

divided into a number of fractions , and then were called mass , calculated for each grain size of the material mass fraction of the total material .

Maintenance issues conveyor main components

    Only the main components of the screw conveyor drive unit ( motor and gearbox ) , spirochetes parts ( housing , shaft and blade ) , material inlet and outlet devices. In the

process of using gravity skatewheel conveyor should regularly check and maintain these key components to ensure that the screw conveyor when the job is trouble-free operation and prolong the

service life of the conveyor . These components require special attention in the maintenance of the following aspects:
   1, the driving device maintenance : the need for filling of the part must be replaced material handling conveyor periodically strict , which is equivalent to the heart of the device , the oil to be

selected in the winter frost oil. Because driven in part by the shaft and connected to the rest , so to regularly check the drive bracket fastening to prevent driving part with

some different heart spirochete deviation occurs .
   2 , spirochetes housing portion Maintenance: housing generally no damage , but if the material is corrosive acid , then should pay attention during idle time for cleaning.
    3 , spirochetes helix axis Maintenance: helix axis is the spiral core pipe and a synthesis of helical blade , spiral blade is also damaged pieces , according to the size of

the abrasive material life is different when the spiral blade and spiral between the housing parts the gap is large, or when you need to replace the blade deformation , or

affect the amount of material transported ; spiral core tube connected to some of the major concerns of the shaft and the lower connecting shaft regular oiling, to ensure

lubrication ; observe the thickness of the spiral sleeve , equipment the most likely long sleeve friction action spiral thinning , thin to a certain extent will affect the screw

shaft concentricity , timely replacement of spare parts should be retained ;
    4 , the main observation material inlet and outlet flange bolts are tightened at the contact , if there is rust and processed.

Vibrating conveyors and conveyor comparison

Vibrating conveyor SCG temperature model is the main representative of the level of vibrating conveyor , screw conveyor as widely and are therefore classified more than vibrating conveyor , a trough and a tube of the points, equipment type on the horizontal / tilt / vertical screw conveyor machine, shaftless screw conveyor and biaxial screw conveyor .
Vibrating conveyor and Flexible skatewheel conveyor conveyor screw conveyor can be angled , but the angle of the screw conveyor can be larger .
Vibrating conveyor are similar to the properties of vibrating screening apparatus , may be provided multi- transport layer or add a degree of screening mesh conveyor , the

conveyor is a pure Extendable conveyor material transport .
Vibrating conveyor length is limited , usually not more than ten meters , while the tube and trough screw conveyor has two forms , either tubular or trough screw conveyor screw

conveyor can be transported over long distances .
Vibrating conveyor is the use of vibration excitation force generated by the motor drive transmission member so that the material moves forward along a certain direction , while

the conveyor is to rely on momentum generated by ordinary motor drives the screw shaft and blade transportation of materials, their different power source .

Belt conveyor speed of friction plate

    High belt conveyor during startup , the use of controllable drive means can reduce the dynamic load ; dynamic load during startup The size starting with the start time and

the acceleration of the growth belt conveyor manufacturer of the law , by analyzing the obtained sinusoidal curve acceleration control ideal start

Dynamic curve .
    In the outlet pressure is constant, the belt conveyor movement speed friction rub the piece the size of the film pressure to a certain extent , the greater the speed , the

greater the centrifugal force , Incline Belt conveyor and the greater the negative pressure , so the film pressure will be reduced . After the porous friction material , the required flow

A flow rate increase.
    When the friction plate is formed with tank when there is conducive to the formation and maintenance of the oil film , and can also reduce wear , effective cooling of the

friction plate; but viscous torque M tank will be somewhat reduced, and as the film thickness thinning , significantly increasing influence tank . With the number of tank

Increases, the friction plate belt conveyor to the transmitted torque can be further reduced.

Screw matching motor selection technique

    Is the use of motor driven screw conveyor spiral rotation, push the material to achieve the transport machinery. It horizontal, check weighers inclined or vertical conveying, transport all

kinds of powder pellets are the ideal equipment . Tubular screw conveyor helical blade material in the transportation of materials, multi-faceted subject to pressure ,

When you need to choose when selecting heat exchange manufacturers the motor power slightly larger, in order to avoid non-normal startup transient excessive power consumption requirements. Trough Screw

Conveyors for its tank for the open type , the material in the upper right helical blade propeller shaft and the pressure ratio is relatively low and thus the electrical Tubular

Screw Conveyors

Machine power requirements slightly lower.
