In this process, the chemical bonds of the raw materials are broken down and then they are,cement manufacturing,Material is fed from inlet and ground materials discharged through the other end of the ball mill. For drying the material, hot air is introduced to remove moisture in the raw material. Grinding can be in two ways viz. closed circuit and open circuit grinding. In open circuit grinding, passage of material is only once through the mill.
