Variables In Ball Mill Operation Paul O Abbe

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. In ball milling of dry solids the main independent variables are mill diameter, mill speed, media size, solids loading and residence time.

Factors Affecting Ball Mill Grinding Efficiency

Factors Affecting Ball Mill Grinding Efficiency

Oct 25, 2017 Mechanisms of grinding in a ball mill can be broadly grouped as either impact or attrition with at least two forms of breakage attributable to each type. Impact breakage may occur as a result of a particle being smashed between balls or between a ball and the mill lining, but is also generally defined to include slow compression fracturing, or crushing of particles between grinding media.
