Modern dry-process cement plants with an efficient grinding and pyro processing system, typically consume less than 700 kcal/kg-cl of thermal energy and 100 kWh/mt of electrical energy. Older plants with inefficient systems, combined with operational and maintenance failure, tend to have much higher energy consumption.

A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. It's mainly used in grinding raw materials and end products in cement plant. Raw mill is made up of feeder part,discharging part,rotating part,transmission part (reducer,samll transmission gear,motor,electric control) etc.

14 Cement Mill and Bag House . Clinker, along with additives, is ground in a cement mill. The output of a cement mill is the final product viz. Cement. In a cement mill, there is a cylindrical shell lying horizontal which contains metallic balls and as it rotates, the crushing action of the balls helps in grinding the clinker to a fine powder.
