Mill (grinding) - Wikipedia

In materials processing a grinder is a machine for producing fine particle size reduction through attrition and compressive 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. Autogenous or autogenic mills are so-called due to the self-grinding of the ore: a rotating drum
