    May 03, 2009· Hi everybody, I am designing a belt feeder to convey coal at 450 TPH, having 35 deg troughing,1200mm wide belt and BD of 850 Kg/cu.m. while I was calculating the capacity for optimum selection I found that the feeder has to run at 1 m/s. but I am in doubt for the maximum speed for belt feeders. Many of readymade belt feeder manufacturers suggests a maximum speed of 0.6m/s.
