Attrition Mills - Powder Metallurgy - Beyond Discovery
2021-7-9 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.. Fig. 24 Attrition ball mill

Attrition mill operating characteristics - ScienceDirect
1975-7-1 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.

Process Parameters in Attrition Milling of Cordierite ...
A commercial cordierite powder was selected to study the particle size reduction under several attrition milling conditions. The influence of milling parameters such as the rotor speed, solid loading, and milling time on the attrition milling process was studied in terms of the particle size distributions, mean diameters, specific surface areas, and media wear contamination of the milled powders.

Cryogenic Attrition Mills - Union Process
Cryogenic grinding is most effective when the product is sprayed with liquid nitrogen as it is being conveyed and introduced into the Attritor. An additional benefit of cryogenic milling in an internally agitated ball mill is the ability to fully immerse the product in liquid nitrogen during milling. The level of liquid nitrogen in the milling ...
