HPGR High Pressure Grinding Rolls

13/07/2016  Primary grinding in the high-pressure grinding roll increases the capacity of an existing dry ball mill operation. Even greater increases in capacity can be achieved if the Polycom is operated in hybrid mode. Hybrid grinding means that a part of the separator tailings (which are recirculated to the ball mill) is diverted and fed to the Polycom together with the fresh feed. Thus, some of the ...

A Review of the Modeling of High Pressure Grinding Rolls

Principle of high pressure grinding The energy efficiency of comminution methods is de-termined by the mobility or confinement of the particles being comminuted (Fuerstenau and Kapur, 1995). Schönert (1996) clearly showed that the most energy- efficient method of breakage is the direct application of force to a single particle or at least a monolayer of parti-cles. The breakage of particles ...
