First order and second order breakage rate of coarse

Abstract: It has been observed by many authors that the breakage rates of coarse particles in a ball mill slow down with increasing grinding time and deviate from the first order. In this paper it is intended to find out whether the breakage rates of coarse particles obey second orderics or not. For this purpose, quartz, limestone, iron ore and a mixture of quartz/limestone weight ratio
