size and the obligation to make more careful use of primary energy. Moreover, the high product throughputs of Loesche mills (up to 1,300 t/h for cement raw material and already 350 t/h for cement clinker and granulated blast furnace slag) result in considerably reduced investment costs compared to two smaller grinding plants.
Energy Use of Fine Grinding in Mineral Processing ...
Media Use and Contained Energy. A wear rate of 7 g/kWh gives a contained energy consumption of kWh contained per kWh of mechanical energy applied. Therefore, 6 to 20 pct of the energy use in fine grinding using ceramic media can be represented by "contained energy" in the grinding media itself.
Slag Cement
Slag cement is produced by finely grinding granulated blast furnace slag, a glassy byproduct of iron production, and blending it with Portland cement to create a product that has a number of advantages over mixes containing Portland cement.
