In a typical grinding circuit, ore is fed into the mills where abrasion, attrition and impact reduce its size, ABB says. Usually, the grinding circuit contains at least two interconnected mills with material classifiers (eg cyclones) separating the fine material from the coarse (that then goes for regrinding).

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 are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (, via a hand crank), working animal (, horse mill), wind or water ().
