Trends in der Minenindustrie
The breakthrough came in 2006 at the Cerro Verde copper ore project (Fig. 8) in Peru. By 2014, a total of 12 HPGRs had been supplied there, completely replacing an SAG concept. The comparison with a conventional grinding circuit with SAGs and ball mills returns a 21 % lower energy demand and annual operating cost savings of almost 15 mill.

Quantifying the energy efficiency of fine grinding circuits
In the first survey the ball mill was underperforming due to the low density in the mill, which was rectified in the second survey. The ball mill was grinding to a P 80 of 50 to 70 µm, therefore the traditional marker size (75 µm) was not applicable, and this can be seen by the increase in SSE for coarser sizes as the marker size approached P ...
