OverviewGrinding machinesGrinding lawsTypes of grinding millsSee alsoExternal links

In materials processing a grinder is a machine for producing fine particle size reduction through attrition pressive forces at the grain size level. See also crusher for mechanisms producing larger particles. In general, grinding processes require a relatively large amount of energy for this reason, an experimental method to measure the energy used locally during milling with different machines was recently proposed.
A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rot
