Effects of Idler Spacing Selection on Belt Conveyor Power Consumption

The effects of idler spacing selection on belt conveyor power consumption were discussed.It uses CEMA standard and considers typical three-roll troughing carrying idler and two-roll "VEE" return idler.To a given belt conveyor(6 000 t/h,8.9 km,5.6 m/s) same speed idler with different idler spacing is chosen,and calculating and comprising belt tension and power consumption.It can offer references for other large belt conveyors design.
