Optimizing cement grinding with chemical additives
Influence on mill retention and void filling. There is an optimum powder filling level in the mill, relative to the media volume to ensure maximum grinding efficiency. This occurs when material fills approximately 85% of the media voids. However, mill operation at high circulating loads often results in a void filling somewhat above this amount.
