factors affecting ball mill grinding efficiencymechanisms 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.

how to measure the impact forces in ball millsunfortunately, the same impacts that break ore fragments deform or crack grinding mill liners. impact test ball. design of an instrumented impact test ball for in mill testing involved several considerations; survival of ball and instruments, retrieval of ball, maximizing generation of impact data, and fabrication of a ball capable of these ends.
