equation. Where: C = Conveyor capacity. r = Material density (kg/m3) V = Belt speed (m/s) A = Conveyor's belt cross-sectional area. Belt speed should be specified such that it does not cause spillage of the raw material being conveyed. Suitable conveyor belt speed typically ranges between 2.5 m/s and 3.5 m/s.Web

Conveyor Systems are mechanical devices or assemblies that transport material with minimal effort. While there are many different kinds of conveyor systems, they usually consist of a frame that supports either rollers, wheels, or a belt, upon which materials move from one place to another. They may be powered by a motor, by gravity, …Web
