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.

Below that size, attrition milling was more efficient in the fines' generation. When the component-based data was interpreted, clinker content was found to be higher in size interval of (-150 + 20) µm. Calcite, on the hand, had higher proportion below 20 µm range owing to its softness and relatively high grindability.
