In a previous paper (Morrell, 2009.Predicting the overall specific energy requirement of crushing, high pressure grinding roll and tumbling mill circuits. Minerals Engineering 22 (6), 544–549), an approach was described to predict the specific energy of a range of tumbling mill and crushing/high pressure grinding rolls (HPGR) circuits.

A novel approach for the modelling of high-pressure grinding …
The pressure exerted by the hydraulic system on the floating roll, that allows horizontal movement of the moving roll, largely determines comminution performance. Typically, operating pressures are in the range of 5–10 MPa, but can be as high as 18 MPa. For the largest machines, this translates to forces of up to 25,000 kN (Morley, 2006).

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 author's data …

With respect to modelling of the high-pressure grinding roll, the most important work was done by Morrell and some co-authors (Morrell et al., 1997, Daniel and Morrell, 2004). The Morrell et al. model consists of three parts: a model for the prediction of product size distribution, a throughput model and a power consumption component.
