Conveyor Idler Degree and Its Impact. One of the key factors in idler placement is the conveyor idler degree, which refers to the angle at which the idlers are set relative to the horizontal plane. This angle determines the trough depth and shape of the conveyor belt, affecting load distribution and material containment.
