MATHEMATICAL MODELS OF PARTICLE SIZE DISTRIBUTION

High-pressure comminution operations also affect the grinding kinetics in downstream milling stage, through shortening the grinding time. Another method of enhancing the grinding effectiveness is an increase of grinding media charge (Olejnik 2006), but here the gain is obtained with no extra cost of grinding media.

Mill (grinding) - Wikipedia

High pressure grinding rolls. A high pressure grinding roll, often referred to as HPGRs or roller press, consists out of two rollers with the same dimensions, which are rotating against each other with the same circumferential speed. The special feeding of bulk material through a hopper leads to a material bed between the two rollers.
