The effects of grinding media shapes on the grinding kinetics of cement
The effects of balls and cylinders on the clinker's specific rate of breakage were investigated. The results showed that the specific rate of breakage provided by cylinders is higher than that of balls. − 2.00 + 1.70 mm is an optimum feed size for 20 mm diameter balls and 20 × 20 mm diameter cylinders.At that feed size, the value of Si is …
Clinker size and cement grinding | GCP Applied Technologies
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 in some cases the formula will result in the prediction that 100mm balls be used to deal with large clinker particles.
