Dry process of cement – we civil engineers

The dry materials exiting the mill are called "kiln feed". Size of the kiln needed for manufacturing of cement is smaller. Difficult to control mixing of Raw materials, so it is difficult to obtain a better homogeneous material. Fuel consumption is low i.e., 100 kg of coal per tonne of cement produced. Cost of production is less.
