Ceramic Grinding Kinetics of Fine Magnetite Ores in the Batch Ball Mill
However, when ground with ceramic balls at the same total weight, the breakage rate is basically around 0.20 min −1, which is close to that of steel ball grinding. Furthermore, when the feed size was larger than 0.212 mm, the average breakage rate of ceramic ball grinding was 8.41% lower than that of steel ball grinding.
