a Stirred Ball Mill" presented at the Powder Bulk Solids Conference, Chicago, Illinois, May 1978. For specific energy input around 100 ksh/t, the media particle size achieved through the use of attritors is nearly onehalf smaller than that obtained from conventional ball mills, onethird smaller than vibratory mills. For energy inputs

The Attritor is often referred to generically as a "stirred ball mill." The operation of an Attritor is simple and effective. The material to be ground is placed in a stationary tank with the grinding media. Carbon steel, stainless steel, chrome steel, tungsten carbide, and ceramic balls are commonly used media.

The introduction of lower temperatures during cryomilling curbs recrystallization and embrittles materials so they can be fractured more easily with mechanical milling. Cryogenic grinding is often performed in impact mills and hammer mills, but the use of an internally agitated ball mill, like an Attritor, can provide additional benefits.

Grinding time is related to media diameter and agitator speed via: T = KD 2 /N 1/2. where T is the grinding time to reach a certain median particle size, K is a constant that depends upon the material being processed, the type of media and the particular mill being used, D is the diameter of the media, and N is the shaft rpm. This equation shows that total grinding time is directly ...
