The circulation grinding Attritor ("Q" machine) is a combination of an Attritor and a large holding tank which is generally about ten times the size of the Attritor. The unique principle of the "Q" Attritor is the high circulating (pumping) rate, which results in a faster grind and a narrower particle size distribution.

Wet mills can also be adjusted to reduce the likelihood of wear to the milling media or grinding chamber. If a product needs to be in a dry powder format, after wet milling it requires an energy-intensive drying process. Dry milling techniques, including fluidized jet milling with superheated steam can save this step, possibly also sparing costs.

Dry grinding, as in a jet mill, uses a single pass process; material enters the mill, passes through, and is expelled, reduced in size. In contrast, wet grinding uses a process of recirculation . The slurry is exposed to the grinding media over and over, for hours if necessary, until the desired particle size is achieved.

Grinding was carried out in the laboratory ball mill described in Table 1, at a low ball load of 20% of the mill volume filled with the ball bed and a low powder load corresponding to a formal interstitial filling of void spaces of the ball bed of U=0.5. These conditions were chosen since it is known that they give first order grinding kinetics for normal grinding, both dry and wet.
