mills (Sinnott et al. 2006; Cleary et al. 2006b). Most of the grinding in tower mills is thought to occur within a high shear, annular zone located between the outer edges of the rotating screw and the stationary mill shell. The breakage mechanism in tower mills is different to that of tumbling mills.

• #### 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), working animal (e.g., horse mill), wind or water ().
