The principle objective for controlling grinding mill operation is to produce a product having an acceptable and constant size distribution at optimum cost. To achieve this objective an attempt is made to stabilize the operation by principally controlling the process variables. The main disturbances in a grinding circuit are: 1.

Stirred mills provide better agitation of small grinding media by inducing larger momentum gradient than the tumbling mill. They are recognized to be more efficient than tumbling mills, especially for fine grinding applications. The stirred mill is a fine grinding device capable of producing product particle sizes less than 1 μm.

Secondary Grinding Ball Mills. In secondary ball milling, abrasive and corrosive conditions predominate. The smaller balls [< 2½", (65 mm)] typically used in secondary milling environments effectively reduce the impact component of wear to the point where grinding media must be primarily designed to reduce abrasive and corrosive wear.

Disc Mills. Disc mills are probably the most ancient type of grinding equipment. Their principle of action is as follows: the material passes between two rotating discs, causing friction of particles against the discs and grinding (Figure 1 a).Mills with a variable gap between the discs and discs with notches are used to increase the milling efficiency (Figure 1 b).
