An analysis of the energy split for grinding coal/calcite ...

2016-7-1  However, the presence of SCAC in mixture reduces the grinding energy efficiency of calcite, with the energy split ranging from 1.70 to 1.83. These conclusions are the same with the study of Kapur and Fuerstenau (1988). Based on the energy balance and energy split factor, specific energy consumed by components can be calculated.
