Technical Research and De elopment Center of Kailuan Federation Electromechanical Factory, Tangshan 063103, China; 2. Training School of T angshan College, T angshan 063020, China) Abstract: Idlers are the main parts in belt con eyors, which are quite expensi e. There are arious types of them and they are mostly used. Whether the choice of the idlers is reasonable will directly affects the earlier in estment, the usage and the reparation of them. So it is ery important to choose and utilize idlers.
