Factors Affecting Ball Mill Grinding Efficiency. Furthermore, as mill performance is related to the complete size distribution of the feed material, all preceeding stages of comminution and classification which influence feed size distribution will have an effect on the performance of the grinding machine.

In this article, alternative forms of optimizing the milling efficiency of a laboratory scale ball mill by varying the grinding media size distribution and the feed material particle size distribution were investigated. Silica ore was used as the test material.

For scale-up~ of lifters in the ball mill under similar grinding conditions, this value of kl~ can be put in Eq. 4 to predict the disappearance rate of the feed at any time, or in the general solution of Eq. 1 to predict the particle size distribution of the product at the desired grinding time.

Effect of Liner Profile on the Trajectory. Figure 3 shows the trajectory of a disc as the face angle of the lifter bars decreases. The speed of the mill was kept at 63% of the critical speed. The face angle was varied from 90 to 111 degrees for the three types of configuration 1, 2 and 4, as shown in the figure.

Ball mill operation is often regarded as something of a mystery for several reasons. Ball milling is not an art it’s just physics. The first problem will ball mills is that we cannot see what is occurring in the mill. The other problem is that many of the independent variables are non-linear or have paradoxical effects on the end results.
