Attritor Mill Technical Papers | Union Process Inc.

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 ().

Choosing the Best Media Mill For Your Wet Grinding Application

technology was neglected by the minerals industry until the 1950s when the tower mill, a type of stirred mill, was developed by the Japan Tower Mill Company (later renamed the Tower Mill Corporation). The development of the tower mill was followed by the introduction of the stirred mill detritor (SMD) in the 1960s (Jankovic et al., 2003).
