Abstract | Full Text
Kinetic study using a laboratory steel ball mill was carried out to determine dry grinding properties of andesite sample. The Si (specific rate of breakage) values were determined by using the single sized feed fractions of - 850+600 µm, -600+425 µm and -425+300 µm. Dry grinding of single size intervals showed that andesite followed the first-order breakage law. The breakage parameters of andesite in terms of the Si, aT and α values were determined.
