the belt conveyor is used for conveying different materials from one location to another. the different components of a belt conveyor system typically are electric drives, pulleys, idlers, and a long belt. a simple conveyor system may look like below: the basics of the calculations of conveyor belt design parameters.
Level conveyors: hp=(f x s x (p+m))/33,000 inclined conveyors: hp=((p x b)+(p+m)x f x s)/33,000. effective tension. pull needed to move belt and load horizontally: e= f x (p+m) tight side tension. total tension to move belt and load horizontally: e 2 = e+e 1. slack side tension. additional tension required to prevent slippage on drive pulley: e 1 =e x k.
