The kinetics of batch grinding quartz from a feed of 600 by 425 mm to a product of 80% less than 10 mm have been determined using screening and laser diffractometer sizing for size analysis. The specific rates of breakage decreased by a factor of about three when the material became less than about 100 mm in size, but the primary breakage distribution function also changed to give proportionately
