Energy and Cost Comparisons of HPGR-based Circuits - E & MJ

The HPGR also produced a coarser product than the SAG mill. Thus, the energy needed for crushing, ball milling and material handling was higher for the HPGR option than the SABC circuit. When extending the target grind size to a P80 of 75 μm, the energy savings of the HPGR-ball mill circuit was only 7%.

Quantifying the energy efficiency of fine grinding ...

The OWi results differ significantly (factor of 3 times) whereas the SSE method results are more consistent and show that both mill types produce fine particles roughly in proportion to the energy input. In fact, in four of the surveys, the SAG mill was found to be more efficient at producing circuit product than the ball mill.

Energy Consumption Ball And Sag Mills

That is, the SAG mill produces about 10.76% more than the ball mill in the final product. The average consumed energy at SAG and ball mills to produce one ton of final product was 23.16 kWh/t and 36.05 kWh/t respectively. Thus, the ball mill consumes 12.89 kWh/t, more energy than the SAG mill in producing the final product.
