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
The screw is an essential component of a plastic extrusion machine. Through its turning motion inside a tight fitting barrel, the screw conveys the plastic, melts it and forces it through a die. These three steps are carried out in a continuous process capable of producing extrusions in a variety of lengths.
