The HPGR-ball mill circuit when grinding to 75 um compared to 160 um used an extra 4.6 kWh/mt, but for the SABC circuit it only used an extra 1.8 kWh/mt. 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 ...
A ball mill without the balls, where the ore is ground by impact on itself. Automatic exercise See Asian Option. Automatic gauge control (AGC) Modern rolling mills for flat products use equipment and software to measure the uniformity of thickness, edge consistency, flatness and surface finish of their product during the rolling process.
In ball milling, the desired particle size is achieved by controlling the time, applied energy, and the size and density of the grinding media. The optimal milling occurs at a critical speed. Ball mills can operate in either a wet or dry state.
