Milling in an attrition mill (Fig. 24) is effected by the stirring action of an agitator that has a vertical rotating shaft with horizontal arms. This motion causes a differential movement between the balls and the material being milled, thus providing a substantially higher degree of surface contact than is achieved in tumbler or vibratory mills..
Attrition mills are used for fine grinding operations in the production of spices (pepper, cinnamon, paprika), food (peanuts, grain, cereal), fibers (chips, cork, cellulose) and blendings (face powders, insecticides). The pictures below show pepper and cinnamon, finished products from attrition milling.
The discs of an attrition mill are generally in a vertical position so that materials not capable of reduction can pass by gravity out of the grinding area. 2.3 Roller Mills. A combination of cutting, attrition, and crushing occurs in roller mills. These are smooth or corrugated rolls rotating at the same speed set at a pre-determined distance ...

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 m 2 /g were obtained for alumina and barite, corresponding to 38 and 56 nm equivalent spherical diameter, respectively.

Attrition Mills. Size reduction in attrition mills occurs through the scraping of one surface against another. Particles scrape against each other or against a rigid face. In general, the size of the resulting particles can get near the micrometer level, but in the pharmaceutical industry, demand has increased for particles on the nanometer level.
Stirred Mills – Ultrafine Grinding. In Mineral Processing Design and Operations (Second Edition), 2016. 10.2.4 Operation of Vertical Mills. Vertical stirred mills are usually charged with media occupying 80% of the mill volume which is in sharp contrast to tumbling mills that are seldom charged more than 40% of their volumes to allow space for the tumbling action to develop.
Tower mills: Often referred to as regrind, stirred, or vertical mills, tower mills are used in a variety of mining and ore processing applications.
