Figure 2.21. Typical air classification for a Lopulco or pendulum mill. Some typical figures for power consumption with the Lopulco mill are given in Table 2.3. The NEI pendulum mill. The NEI pendulum mill shown in Figure 2.22, is slightly less economical in operation than the Lopulco mill, although it gives a rather finer and more uniform product.

However, helpful aspects from comminution research, such as Kick's and Rittinger's laws, can be applied to aid in interpretation of attrition data, as knowledge of the energy applied to the material in question, regardless of its source (e.g., gas jet or ball mill) should follow the same laws. This work is divided into several sections.

The attrition mill is a device for mechanically reducing solid particle size by intense agitation of a slurry of material being milled and coarse milling media. For example, in 10 hours of milling, specific surfaces of 40 and 25 m 2 /g were obtained for alumina and barite, corresponding to 38 and 56 nm equivalent spherical diameter, respectively.

Attrition mills use the hammermill principle to a certain extent; i.e., shattering by/impact. However, they also impart a shearing and cutting action. Grinding is done between two discs equipped with replaceable wearing surfaces. One or both of these discs is rotated; if both, they rotate in opposite directions.

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.. Fig. 24 Attrition ball mill
