Breakthrough in Clinker Grinding Massachusetts
2012年11月8日 Finish grinding of clinker and other cement ingredients reduces 25 mm clinker balls to particle sizes optimally ranging from 3 to 30 microns. The European Cement Research Academy (ECRA) estimates that up to 70% of the power consumed in cement production is for material size reduction. Increasing the efficiency of particle size

Clinker size and cement grinding GCP Applied Technologies
2021年2月8日 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

CLINKER GRINDING IN CEMENT PRODUCTION
2019年2月21日 For calculation of factor of saturation used Kind V.A. formula (1). Value KS K = 92 % indicates that clinker is medium grinded, KS K > 92% easy to grind, KS K <92% hard to grind. The lower value KS K, the larger the clinker. Typical KS K values in Portland cement clinker are 0.8-0.98, or 80-98%.
