Attrition Mills Powder Metallurgy Beyond Discovery

Dec 13, 2020· 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..

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.
