### 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

### Prevent Material Blockages - Martin Eng

A steel plant was having trouble with iron ore sticking to the walls of the hopper. The wet and slightly sticky material would accumulate in the hopper creating a blockage. Production couldn’t run smoothly and the plant had to hire people to continuously knock material off the wall of hopper to keep the flow of material running smoothly.
