The current world consumption of cement is about 1.5 billion tonnes per annum and it is increasing at about 1% per annum. The electrical energy consumed in cement production is approximately 110. kWh/tonne, and around 40% of this energy is consumed for clinker grinding.. There is potential to optimise conventional cement …
The efficiency of fine grinding in the second compartment is largely controlled by the size of grinding balls. Due to limitation of the mill's rotational speed, the smallest ball size is usually restricted to about 15 mm. Cement grinding using stirred mills (Pilevneli and Azizli, 1999) indicates that using smaller media (5-8 mm range ...
