Breakage behavior of quartz in a laboratory stirred ball mill

An investigation on the kinetics of grinding quartz was carried out in a laboratory stirred ball mill. In this study, the specific rate of breakage S and breakage function B were determined by one-size-fraction tests. The results showed that below a certain size, the breakage was firstorder and the breakage functions were normalizable.
