High Pressure Grinding Rolls (HPGR)

High Pressure Grinding Rolls (HPGR) Feed material can be smaller than the gap, which is an important distinction as compared to crushers, for example. The high pressure comminution process causes micro-cracks in the particles, which lead to the liberation of minerals and a higher portion of fines. Roll crushers are customized solutions
