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 or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Grinding Mills and Their Types – IspatGuru

Stirred media mills are usually constructed in the form of a cylindrical drum inside which there are a series of rods, arms or perforated discs which are rotated on a central shaft. The drum is loaded with grinding media, such as metal balls or glass sand. The media and the charge is 'stirred' together and thus the grinding takes place.

Solids | Choose the Right Grinding Mill | Chemical …

For attrition milling, media size ranges from 1/8 in. to 3/8 in., with smaller media generally resulting in faster particle reduction — because for a given volume there'll be more impact and surface contact. As media becomes smaller than 1/8 in., mass is significantly reduced, resulting in less impact force and thus longer grind times.
