Sand mill has vertical sand mill and horizontal sand mill points. Usually, the filling amount of grinding medium of vertical sand mill is about 70% of the effective volume of cylinder, and about 80% of horizontal sand mill. The amount of grinding medium of sand mill is related to the viscosity and temperature of grinding material.
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 or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
