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.

Mass/Volume Flow Determination. The relationship between the mass (M) and the volume flow (Q rates in a given stream is defined as: = the pulp density (solids and water) in lbs/ft 3 X = solids concentration in % by weight; Volumetric flow rate can be measured by flow meters, P-Q curve relationships for pumps or directly measured.

The grinding-product size, P, in a Bond ball mill, which is given by the aperture size which passes 80% of the grinding product as a function of the aperture size of the test screen P k, can be expressed by the formula P= P k K 2.
