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 ().
EF4 - Oversized Feed - when the grinding mill is fed a coarser than optimum feed, this factor applies to rod milling and ball milling. The most frequent use is with single stage ball milling. This is the one efficiency factor that is directly related to work index as is shown in the following equation:
In the equation of Time for Cylindrical Grinding Cut. Length of Cut = Length of job + Over-Travel. where, Over-Travel equals to 0.5 cm. And Feed/Rev. = w/2 (for rough cut) or w/4 (for finishing cut). Where, w = Width of Grinding Wheel.
