Development of the conveyor

Conveyor classified according to whether the pulling elements into two categories.
A conveyor having a traction member generally include traction , bearing components , drive means , tensioning means for redirecting means and the support member . Traction

member pass traction , can be used conveyor , drag chain or rope ; carrying member Holds material , there hopper , bracket, or spreader , etc. ; drive

Mobile devices to be material handling conveyor power to the conveyor , generally consists of motor, reducer and brake ( stopper ) and other components ; tensioning devices generally have two kinds of

screw and hammer , pulling elements can maintain a certain tension and sag to to ensure the normal operation of the conveyor ; supporting member supporting the tractor parts or

carrying

Member , can be idlers , rollers , etc.
Having a traction member of conveyors structure: the material to be transported to the traction member mounted on the bearing member are joined together , or in directly mounted

on the pulling element ( such as belt ) , the pulling element of the roller or chain around the end to end, including the transportation of materials to form branches and no -

load transportation of materials

The no-load branch closed loop , using the continuous movement of the pulling element transport materials
Such a wide range of conveyors , the main belt conveyors, slat conveyors , trolley conveyors , escalators , moving walkways , scraper conveyor, buried scraper conveyor, bucket

conveyor , bucket elevator , overhead conveyors and overhead lifts and so on.
Conveyor without pulling element different structure and composition , working member for transporting the material is not the same . Their structure is characterized by : the

use of rotational movement of the work member or reciprocating motion , or by the medium flowing in a pipe conveying the material forward . For example , the roller

Conveyor working member of a series of rollers , the roller rotates to transport materials ; screw conveyor working member of the spiral , spiral chute rotates in order to push

the material along the trough ; vibrating conveyor working member of material groove , trough placed reciprocated to convey

One of the materials, etc.
