Ball mills grind material by impact and attrition. The degree of milling in a ball mill is influenced by; a. Residence time of the material in the mill chamber. b. The size, density, and number of the balls. c. The nature of the balls (hardness of the grinding material) d. Feed rate and feed level in the vessel.

However in this study, the layouts of the mill were changed since larger diameter chamber was used at the same stirrer design (Mill 2) therefore the gap between the stirrer edge and mill chamber wall increased (Fig. 7). For this reason, improved performance was obtained with Mill 2, even if the mills were operated at the same …

The profiling of the shell lining plates creates the movement of the ball charge, which causes the grinding of the material. It is therefore essential for effective grinding in the mill and far more than just a wear part. The exact profile shape has to be defined depending on the ball sizes used, the rotation pace and the mill diameter.
