Effect of grinding aids on closed circuit cement grinding As introduced before, grinding aids are sprayed in the mill, or added on the clinker, with dosages usually ranging from 100-200 g up to 2-3 kg per ton of cement. Once a grinding aid is added during cement manufacturing, the main effect is the reduction of separator reject: more
