ing (e.g., plugging the hammer mill screen or blocking the air classifier of a jet mill), and collection (e.g., plugging the bag filters). There are two ways to grind sticky materials. The first solution is to dry the material prior to grinding, or dry and grind it at the same time by sweeping hot air through the mill.

operated 60-70% mill load, at rates of 8-22 ton; the quality was 5-10% fines. Die selection is a function of quality and production rate. Die speed (RPM) is a function of the feeds to be pelleted, for example, feeds containing fat or 50-60% corn. Perhaps it is more judicious to refer to peripheral speed of a die rather than RPM.
