2018-3-29 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

Cement is produced by co-grinding clinker, gypsum and other components defined in the Ce-ment Standards like limestone, pozzolans, fly ash and slag. The grinding is usually performed in hor-izontal ball mills. Gypsum is typically the basic source of sulphates (SO 3) in the cement. The effect of gypsum on the cement quality is critical and two-fold.
