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 ().

This is obtained for a comminution device using Eq. (5.4) by measuring W (the specific energy being used kWh t −1) F 80 and P 80 and solving for Wi as the operating work index Wi O. (Note that the value of W is the power applied to the pinion shaft of the mill. Motor input power thus has to be converted to power at the mill pinion shaft output by applying corrections for electrical and
