Attrition Mills - Kinergy
Attrition Mills. An Attrition Mill is used for reducing "no bake" bottom sand lumps to "grain size" of minus 20 mesh or green sand to small particles. Sand is dumped into the rear hopper section. The lumps rub on one another and produce "fine" grains which can convey up a steep incline.

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
Attrition mill operating characteristics - ScienceDirect
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.

43.1 Introduction. Size reduction of solids involves creating smaller mass units from larger mass units of the same material. To bring this about, the larger mass units need to be subjected to stress by the application of force. Three types of force may be applied, i.e. compression, impact and shear.
