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..

Attrition Mills. An Attrition Mill is used for reducing "no bake" bottom sand lumps to "grain size" of minus 20 mesh or green sand to small particles. Sand is dumped into the rear hopper section. The lumps rub on one another and produce "fine" grains which can convey up a steep incline. A screen deck near the discharge end removes ...

Attrition mill : IN this case, the charge is ground to fine size by the action of a vertical shaft with side arms attached to it. The ball to charge ratio may be 5:1, 10:1, 15:1. This method is more efficient in achieving fine particle size. Rod mills: Horizontal rods are used instead of balls to grind. Granularity of the

The configuration of the attrition mill's agitator system causes constant motion of material around the tank. The area of greatest media agitation is located approximately two-thirds the radius from the center shaft (Figure 2). In production-sized units for wet milling, a pumping circulation system augments the movement.

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.
