· Most Cement Clinkers grinding experiments were carried out in a 29.2 cm diameter laboratory ball mill which had a built-in wavy liner. The ball charge consisted of 1.27, 1.90 and 2.54 cm steel balls mixed in equal proportion by number. The ball load corresponded to 40% filling of the struck volume of the mill (denoted by: J = 0.4), and the …
· 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 ...

This paper seeks to evaluate the scale effect by comparing the results …
· For this reason, the structure of the clinkers in the grinding stage is very important. To make it clear, more energy is spent when grinding the clinker material with a hard structure compared to grinding the clinker material with a soft structure. The condition of grinding is not the only criteria for the formation of this micro-structure.
