Grinding Mill an overview ScienceDirect Topics

The tumbling grinding mill (Fig. 2) is the solution to the problem of applying a relatively small fracture force to a large number of particles. Such mills are cylinders, rotating about the axis, containing a tumbling grinding media, which produces predominantly shatter fracture (because of the relative high energy intensity) as the mineral stream flows through the mill.

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 ().
