The comminution efficiency of a HPGR is better than ball mills such that it consumes 30–50 % of the specific energy as compared to a ball mill. Four circuit configurations of HPGR can be used in grinding of raw materials, clinker and slag such as : Pre-grinding unit upstream of a ball mill. Hybrid grinding. Semifinish grinding
The grindability index is often calculated from the number of mill revolutions required to achieve a predetermined cement fineness.(either Blaine or sieve residues) This can be determined by taking representative samples from the lab ball mill after successive incremental numbers of revolutions, and testing these samples for fineness.
Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill, Coghill and DeVaney (1937) defined the ball size as a function of the top size of the feed, i.e.,
