Alternatively, ball mills are closed systems and do not offer these advantages. Nevertheless, ball mills can be a more appropriate choice for grinding larger sized material starting at 1/4 " or larger. It should be noted that ball mills are much larger than Attritors and therefore require a special foundation.
The mill used in this experiment is made of alumina with an inside diameter of 144 mm and an inner volume of 2100 cm 3, and the grinding ball is also made of alumina.Five ball diameters ranging between 3 and 30 mm were used, and feed size was varied in the order of 10 −3 to 10 −1 as a ratio of ball diameter. Feed sizes and ball diameters used are shown in Table 2, Table 3, Table 4.

These ball materials are often used because they are inexpensive. Nylon is one of the most common plastic ball materials. It is hard, it is tough and it is dense enough so that it sinks in water. Nylon is slightly hygroscopic, so it isn't the best plastic to be used in water applications. PTFE. is a fairly common plastic ball material.
Abstract The present study deals with an analysis of the selection function for mills using balls as grinding media. The grinding mechanism assumes that a particle caught by two colliding balls will be ground only if the ball impact generates or activates at least one single crack within the particle causing the fragmentation. The derived selection function becomes convex in relation to ...

Some devices, such as ball mills, are more suitable for coarse materials. These mills use "large" media, ranging in size from 20 mm in diameter and up, to produce material from about ten microns to mesh sizes. Attrition mills are more appropriate for "mid-range" size particles. Such mills utilize 3–10-mm media to produce material ranging in ...
