This quantity is small compared to the power used by a semi-autogenous mill and a ball mill in a primary grinding circuit; a ball mill can have an installed power of up to 15 MW, while installed power for a SAG mill can go up to 25 MW. However, the energy used for fine grinding is still significant.

the application of ball mill power from fine (minus P80 product size) to coarse material, circuit efficiency is increased and overgrinding is ... hardness, and other factors. Consumption is closely related to total ball charge surface area. • A useful guideline for make-up ball size for a new circuit was provided by Bond (1958).

Power consumption will drop, and product fineness (Blaine) will deteriorate. Effectively, a further increase in moisture will render the HPGR feed and product to act as a wet pulp slurry. For a sample of a Carajas ore, a series of tests was carried out using a 1-pass and 2-pass arrangement across a moisture range between 6% and 9% ( Table 3 ...

The reported SABC circuit power for the 160 μm grind size was based on actual site data. JKSimMet was used to fit a model to site DCS data. Thus, there was considerable scope to reduce the ball-mill power consumption by using smaller ball-mill grinding media. However, for a final grind of 75 μm, the reported power values for both HPGR-ball ...
