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.

Attrition Scrubbers 911Metallurgist

The general use of attrition scrubbers is to break down these clays, whether found in sand size particles or as coatings on the surface of sand grains, to allow for their rejection. Attrition scrubbing cannot change or alter the grain shape. If the particles arc not round, no economically justifiable amount of scrubbing will change that fact.
