INVESTIGATION ABOUT THE EFFECT OF CHEMICAL GRINDING .

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 100200 g up to 23 kg per ton of cement. Once a grinding aid is added during cement manufacturing, the main effect is the reduction of separator reject: more

ball mills are also in closed circuit with classifiion systems such as cyclones. An alternative to crushing is to feed some coarse ores directly to wet or dry semiautogenous or autogenous grinding mills (using larger pieces of the ore to grind/mill the smaller pieces), then to pebble or ball mills.
