How to Design Efficient and Reliable Feeders for Bulk Solids

How to Design Efficient and Reliable Feeders for Bulk Solids by John W. Carson, Ph.D. and Greg Petro, P.E. A feeder is an extremely important element in a bulk material handling system, since it is the means by which the rate of solids flow from a bin or hopper is controlled. When a feeder stops, solids flow should cease. When a
