Cement mill tension pressure

Feb 01, 2006 Plant 1 feed was the product of a wet AG-pebble mill circuit and the specific energy consumption was 39 kWh/ton. Plant 2 feed was the product of wet rod mill-ball mill grinding circuit with F 80 of about 20 mm. The energy consumption was 25.5 kWh/ton for this application. As given in Table 3, the HPGR circuit consumed 8 kWh/ton. These results
