### Design Considerations for Conveyor Belt Idlers

There are three types of idlers used in the conveyor industry, out of which only the flat belt conveyor idler design calculations are discussed here theoretically. We have not used the factor of safety in the design calculations here, or in other words the factor of safety is .

### Design Considerations for Conveyor Belt Idlers

Capacity of the conveyor W = 1000 t/h. Belt speed V =1.68 m/sec. Belt tension near idler T1=50000 N. Idler length L =1.2 m. Belt sag = 0.015 m. Weight of the belt =15 kg/m. Idler speed N= 50 rpm. Design procedure: First, we will calculate the weight of the conveyed material using the eqn.1.2 as: ml = (10*1000)/(36*1.68) = 165.34 kg/m
