The grinding media play an important role in cement industry, and these balls suffered from severe wear during the grinding process of clinker inside horizontal mill.
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 …

Ball mills (Fig 1.1) are coming in cement plant areas of raw grinding, coal grinding and cement grinding which in turn as raw mill, coal mill and cement mill. Ball mills are horizontal tube mills having single or two compartments for grinding, Balls as grinding media and driven by side or central drive.
The model structure for the one-chamber or multi-chamber cement ball mills have been subject of various researchers. Benzer et al. [21] developed model for open circuit two-chamber cement ball mill. In their structure, the first and second chamber of the ball mill as well as the intermediate diaphragm were all model fitted hence calibrated …
Vertical roller mills and ball mills represent two clearly distinct technologies. However, with proper adjustments to the operational parameters of the vertical roller mill almost identical cement properties can be achieved by the two mills that satisfy the cement user's demands.Nevertheless, the two types of mills have their distinctive merits.
Nowadays, ball mills are widely used in cement plants to grind clinker and gypsum to produce cement. The research focuses on the mill speed as well as air classifier speed effect on the two ...

The characteristic tumbling motion of these mills has given them the name 'tumbling mills', which include the ball mill, tube mill and rod mill. Ball mills are horizontal rotating cylindrical or conical steel chambers, approximately one third to half full of steel, alloy steel or iron balls, like that shown in Fig. 4.10 A–C, or flint stones.
