Belt Conveyors for Bulk Materials - Fifth Edition - Chapter 6

the belt and the idler rolls can be calculated by using the multiplying factor K x . K x is a force in lbs/ft of conveyor length to rotate the idler rolls, carrying and return, and to cover the sliding resistance of the belt on the idler rolls. The K x value required to rotate the idlers is calculated using equation (3).

belt conveyor depends on the surcharge angle and on the inclination of the side rolls of three-roll troughing idlers. The nominal cross section of the material on a belt is measured in a plane normal to the belt. On an inclined or declined conveyor, the material tends to conform to its surcharge angle as measured in a vertical plane. This decreases the area, Asc, as the cosine of the angle of conveyor
