Classification of Conveyors

Posted on February 22 2013 by A conveyor belt having traction pieces typically includes traction pieces, bearing member, driving device, tensioning device, redirecting device and support pieces. in conveyor belt manufacturers, conveyor belt system, belt conveyors for bulk materials

Conveyors are generally classified according to the presence or absence of traction pieces.



A conveyor belt having traction pieces typically includes traction pieces, bearing member, driving device, tensioning device, redirecting device and support pieces. Traction parts are for the passing of traction and can use conveyor belt, pulling chain or wire rope; bearing member is for bearing materials, including material hopper, bay or spreader; driving device provides power to the conveyor drive unit and is generally composed of an electric motor, speed reducer and brake stopper; tensioning device generally has screw type and heavy hammer type which can maintain a certain tension and sag on traction pieces in order to ensure the normal operation of the conveyor belt tensioning device; support pieces are for bearing the traction pieces or bearing components, and may be idlers, rollers. The conveyors produced by professional conveyor belt manufacturers have high quality parts.

Structural features of a conveyor device having traction pieces:



The material transported within the bearing member is mounted on the link together with the traction pieces, or mounted directly on the traction pieces (such as a conveyor belt). The traction pieces bypass the respective rollers or sprockets to be the closed loop which includes connected load branch and no-load transportation of materials branch to convey materials by using the continuous movement of the traction pieces.

This type of conveyor belt system has wide varieties, like conveyor, slat conveyors, trolley conveyors, escalators, moving walkways, scraper conveyor, buried scraper conveyor, bucket conveyor, bucket elevator overhead conveyors, aerial tramway, and so on.

The conveyor equipment without traction pieces has different structures composition. The working parts of transporting materials are not the same as well. Their structures are characterized by: using the rotational movement or a reciprocating motion of the working member, or using the medium flowing in the pipeline to make the material fed forward. For example, the working member of the roller conveyor is a series of rollers which convey materials by its rotational movement; the working member of the screw conveyor is a spiral which can push the material along the chute by helical trough for rotating movement; vibrating conveyor's member is a trough, which can convey the material therein by the reciprocating movement.
