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 are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (, via a hand crank), working animal (, horse mill), wind or water ().
Attrition mill (attritor) is applied in the production of fine particles in chemical, pharmaceutical and mineral processing industry, and also, in the process of intensifying of the mineral waste and providing cleaning efficiencies (Schaaff et al. 1999). Attrition mill (stirredball mill) enables the .
The attrition mill is a device for mechanically reducing solid particle size by intense agitation of a slurry of material being milled and coarse milling media. For example, in 10 hours of milling, specific surfaces of 40 and 25 m2/g were obtained for alumina and barite, corresponding to 38 and 56 ...
A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati

The power characteristics of the attrition mill were comparable to those of a radialflow turbine mixer in a completely baffled, cylindrical, flatbottom tank. The breakup of laminar flow occurred at NRe>8,000.
However, the attrition grinding techniques have shown to be quite effective in producing mineral particles below the one pm range (Sadler et al., 1975). The applicability of attrition grinding in hydrometallurgical operations is a subject of intensive research (Gerlach et al., 1973; Beckstead et al., 1976).
