High Pressure Grinding Rolls. High pressure grinding rolls (HPGR) technology was first utilized in the grinding of clinker and raw material in the mid-1980s and has quickly proved be an economical choice in comminution process. 3 It utilizes the same compression method as the VRM to break the particles to the desired fineness. The HPGR compresses the material into a cake that includes both fines and
