Ball Mills an overview ScienceDirect Topics

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 11.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 2040% water by weight.

Correlation between process parameters and milling efficiency

An experimental ballmilling study was performed to compare the deagglomeration The evaluation of the effect of the process parameters on milling efficiency was facilitated by the use of simple scaling factors. For example, all milling curves for Many powders that consist of more than one component, like hard metal powder, have to be
