Roller mills have a larger capital cost but use less horsepower per ton, and they may require screening to get a specific grain size distribution. Because it is an abrasive grain, corn may wear out a roller mill. Cage mills. A cage mill consists of one or more rotating cages enclosed in a steel housing.
Roller mills accomplish size reduction through a combination of forces and design features. If the rolls rotate at the same speed, compression is the primary force used. If the rolls rotate at different speeds, shearing and compression are the primary forces used.
