For this coarser feed the 50 + 20+10 mm ball diameter mix breaks the material at a faster rate compared to the other ball matches. The availability of a ball size for a particular feed size ensures breakage occurs at a faster rate. The 10 mm ball size is unable to nip the large particle size hence the breakage rate is slower.

Principle of Ball Mill: The size reduction in the ball mill is a result of fragmentation mechanisms (impact and attrition) as the balls drop from near the top of the shell. Mixing of feed is achieved by the high energy impact of balls. The energy levels of balls are as high as 12 times the gravitational acceleration.

The ball mill is used for the grinding of a wide range of materials, including coal, pigments, and felspar for pottery, and it copes with feed up to about 50 mm in size. The efficiency of grinding increases with the holdup in the mill, until the voids between the balls are filled. Further increase in the quantity then lowers the efficiency.

The process of ball milling and the materials that compose planetary ball mills are highly complex, and the existing research on the change in ballmilling energy is not mature. The theoretical model of a ball mill was established for the first time to simulate the motion, collision process, energy transfer, and temperature change of small balls during the ballmilling process. Furthermore, by ...

As one of the machines widely used in mining, a semiautogenous grinding (SAG) mill can significantly improve the roughing efficiency of rock. But the SAG mill still faces the obstacles of significant energy consumption and empirical operation parameters. In order to obtain the optimal operation parameters of a SAG mill, in this paper, the discrete element method (DEM) is used to simulate the ...

The circulation grinding Attritor ("Q" machine) is a combination of an Attritor and a large holding tank which is generally about ten times the size of the Attritor. The unique principle of the "Q" Attritor is the high circulating (pumping) rate, which results in a faster grind and a narrower particle size distribution.
