Comparison of intergrinding and separate grinding for the

May 01, 1999· For cements containing blast furnace slag, unlike the natural pozzolan-incorporated cements, intergrinding consumes more energy than separate grinding to reach 3500 cm 2 /g Blaine fineness. However, the lower energy-consuming separately ground P + S cement still shows lower strength values than higher energy-consuming interground PS cement.

The effect of foamy slag in electric arc furnaces on

energy consumption in electric arc furnaces are scrap preheating, stirring, use of burners and hot charge and foamy slag. Between these methods, use of foamy slag is the most useful and economic factor. Foamy slag can reduce the amount of energy, electrods, refractory consumption, tap to tap time and increases productivity.
