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.. Fig. 24 Attrition ball mill

ATTRITOR GRINDING MILLS AND NEW DEVELOPMENTS

The HSA Attritor is generally used in a continuous mode. The material is charged into the mill at the top by a pre-set rate feeder, and discharged out the lower side of the grinding tank. HSA Series Attritors are generally used for finer feed material (-40 mesh), and produce
