A comparative study on the effects of dry and wet

2019-9-1  The S ratio between dry and wet grinding for various materials varies from 1.1 to 2.0. In the inter-particle breakage mechanism, particles are broken by compression. Particles in a high-pressure grinding roll (HPGR) are crushed by inter-particle breakage mechanism. HPGR as a dry comminution method was commercialized since the 1980s.
