Conveyor Belt Basics

Conveyor belt classification

Conveyor belts are generally based on the presence or absence of traction members, carrier purchases, drive units, tensioning devices, redirecting devices and supports. The traction member is used for transmitting the traction force, and the conveyor belt, the traction chain or the steel wire rope can be used: the bearing member is used for receiving the material, and the hopper, the bracket or the spreader, etc.: the driving device powers the conveyor, generally by the electric motor, the speed reducer and Brake (stop) and other components: The tensioning device generally has two types of screw type and heavy hammer type, which can maintain the tension and sag of the traction member to ensure the normal operation of the conveyor belt: the support member is used to support the traction member or the bearing member. , can use rollers, rollers, etc.


The structural feature of the conveyor belt device with the traction member is that the conveyed material is installed in the load-bearing structure connected with the traction member, or directly on the traction member (such as the conveyor belt), and the traction member bypasses the rollers or the sprocket head and tail. Connected to form a closed loop comprising a loaded branch of the transport material, conveying material using continuous motion of the traction member

There are many types of conveyor belts, such as belt conveyors, slab conveyors, trolley conveyors, escalators, moving walkways, scraper conveyors, and buried scraper conveyors. Bucket conveyors, hanging conveyors, aerial ropeways, etc.

Conveyor belt equipment without traction members have different structural components, and the working members for conveying materials are also different. Their structural features are: using the rotary motion or reciprocating motion of the working member, or using the flow of the medium in the pipeline to transport the material forward. For example, the working member of the roller conveyor is a spiral, and the working member of the screw conveyor is a spiral. The spiral makes a rotary motion in the trough to push the material along the trough, the working member of the vibrating conveyor is a trough, and the trough reciprocates to transport the materials placed therein.
