Cement Kilns: Size Reduction and Grinding

The development of all-steel media allowed maximum grinding effect in these mills, but the rate of wear of these media was very high, often around 1 kg per tonne of material ground. Although hard alloys were available, they tended to be brittle, and hard media would break into irregular pieces, causing a rapid reduction in grinding efficiency.
