Section snippets Grinding kinetics in the Bond ball mill. Tests of grinding kinetics in the Bond ball mill (Fig. 1, Fig. 2) has shown that over a shorter grinding period, the process follows the law of first order kinetics R = R 0 ekt where R = testsieve oversize at the time (t); R 0 = test sieve at the beginning of grinding (t = 0); k: grinding rate constant; t . = grinding time.

Limestone/quartz (Ls/Qz) feed mixtures were prepared in the proportions 10, 25, 50, 75, and 90%, as well as grinding each material alone (100%), and ground dry. These two materials were chosen not only because of their differences in grindabilities and their similar densities but also to simplify size analysis.
Ball mill is mainly used for grinding in mining (metallic minerals and nonmetallic minerals), cement, refractories, chemical, power plant, aluminum, building material, glass, ceramic, steel slag and fly ash, follows more crushing and less grinding principle to save energy. The feed size to ball mill shall be smaller than 25mm, the output size can be adjusted by revising steel balls ratio.
