As a general rule, there should be less than 25% of clinker that is below 1mm in size. Coarse clinker is more of an issue for ball mills. Some cement groups use a formula, such as Bond's, to calculate the maximum ball size required in a ball mill, based on the average size of the clinker feed. However, one drawback with this approach is that ...

The decrease in motor power consumption from 79% to 73.2% of ultimate capacity is another indicator of improved clinker processing. The mill sound and power consumption were re-adjusted to around 82.1 ± 0.8 dB and 79.4% ± 0.1%, respectively, by increasing gradually B0 to 101.5 ± 1.5 ton/h ( Table 3 ).

Step 2: clinker sintering. Clinker sintering is a crucial link in clinker calcination, which mainly occurs in the cement kiln. Inside the kiln, raw meals are heated by rising temperature and generate a series of physical and chemical reactions. When the temperature reaches its peak, the clinker will be produced by rapid cooling.
