High pressure roller press can be introduced as a pre-grinding step for the ball mill, in order to decrease specific power consumption in finish grinding and/or to increase the output of finish mill. Grinding capacity of finish mill increases by about 30%. Up to capacity increases are reported in India with the use of this approach.
High pressure roller press as pre-grinding to ball mill: Specific power consumption decreases by about 10%. Reductions in specific energy consumption in the range of 7-24 kWh/t-cement are reported (LBNL, 2008) Power consumption per ton of cement can be reduced by 8 ~ 12 kWh, representing 15% to 30% saving over a traditional ball mill system.

The ...
In a high-pressure roller press, two rollers pressurize the material up to 3,500 bar, improving the grinding efficiency dramatically and significantly reducing energy consumption. High-pressure roller presses are most often used to expand the capacity of existing grinding mills, and are found especially in countries with high electricity costs or with poor power supply.
