The milling was conducted in a batch system, for diversified compositions of balls. The milling product was subjected to granulometrical, morphological and strength analyses. On the basis of the developed Reid's theory and using the Austin-Gardner equation, a form of the function circumscribing the specific rate of comminution of selected size fractions was determined. The values of the breakage rate function bi, j for the mill's apparatus conditions were determined. The impact was investigated for a variable number of grinding media contact points on the values of specific rate S and the values of the breakage rate function bi, j. Furthermore, the values of coefficients occurring in the equations circumscribing the specific rate of milling S and breakage parameter bi, j were determined.}, type={Artykuły / Articles}, title={Analysis of the breakage rate function for selected process parameters in quartzite milling}, URL={http://www.czasopisma.pan.pl/Content/84690/PDF/11-ZS-paper-Olejnik.pdf}, doi={10.2478/v10176-012-0011-4}, keywords={ball mill, specific grinding rate, grain morphology, contact points}, }
