  • Factors Affecting Ball Mill Grinding Efficiency

     · 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.
