Mill (grinding) - Wikipedia

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes. There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank),.

However, this kind of complicated motion plus the motion of a ball relative to the bottom of a mill pot (rolling and sliding) can strongly squeeze, rub, and crush the powdered materials, so that the grinding capacity can be increased dramatically. The above kinematics and kinetics analysis is based on the case of one single.
