The mills that operate on the direct mode are classified into attritor, pan and roll (Fig. 3 A). The attritor mill is a versatile equipment because it can operate under different conditions either wet or dry. It is composed of a vertical stationary tank that contains the sample to be milled alongside the grinding media.
