The opening is closed and the mill is rotated for several hours. It is then stopped and the product is discharged. 5. The ball mill is used for grinding materials such as coal,pigments,and fedspar for pottery. Grinding can be carried out in either wet or dry but the former is carried out at low speeds. The advantages of wet grinding are less ...

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..
