Variables in Ball Mill Operation | Paul O. Abbe®

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.

Variables Affecting Grinding Mill Power

On account of the lifting effects of the ends, a mill 2 feet long is expected to take a little more than half as much power as a mill 4 feet long. Correction for length was made in a recently developed formula for power, but other variables, such as the amount of ore in the mill, were too intangible to be corrected.
