Comminution is the reduction of solid materials from one average particle size to a smaller . Within industrial uses, the purpose of comminution is to reduce the size and to increase the surface area of solids. It is also used to free useful materials from matrix materials in which they are embedded, and to concentrate minerals.
Size reduction equipment included a knife mill, hammer mill, and disc mill. . For minerals, power = (particle size)^ 3/2 and is related to molecular bonds. . determined using ASABE forage sieve methods (ANSI/ASAE S424.1, DEC01, 2006).
