formula for critical speed ball mill. The formula for critical speed is CS = 1/2π √(g/(R-r) Ball milling is one of the few unit operation that improves with increasing mill diameter. If acceptable results can be obtained with a 12" jar mil, then good result will certainly be obtained with a 72" diameter mill
