How to Reduce Steel Consumption in Grinding Mills

The overall wear of the steel in the grinding mills occurs as a peeling of the steel surfaces at a constant radial rate per unit time. This concept although challenged at times was first introduced by Prentice in evaluating the wear of grinding balls, and subsequently demonstrated on large ball mills. The radial wear rate of the steel grinding

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 ().
