• Chapter 18. Feed Milling Processes

    The discs of an attrition mill are generally in a vertical position so that materials not capable of reduction can pass by gravity out of the grinding area. Roller Mills. A combination of cutting, attrition, and crushing occurs in roller mills. These are smooth or corrugated rolls rotating at the same speed set at a predetermined distance apart with material passing between the two. A ...
