· 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.
