High pressure grinding rolls or HPGR is such a kind of equipment that uses this principle for crushing operations. HPGR has been widely used in fine crushing of metal ore beneficiation plants, crushing in cement industry, granulation in chemical industry and fine grinding of pellets to increase specific surface area.
In AG/SAG-based circuits the need for W s appears to be unnecessary as Fig. 2 illustrates. Primary crusher feeds often have the shape shown in Fig. 2 and this has a very similar gradient to typical ball mill cyclone overflows. A similar situation appears to apply with HPGR product size distributions, as illustrated in Fig. 3.Interestingly the …
