Breakthrough in Clinker Grinding - Concrete …

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 reduction could

Fineness test of cement | Formula with Table of Calculation

The proportion of cement size greater than 90 microns is considered as fineness cement. In other words, the fineness of the cement is the particle size of cement. The maximum residue after the sieving in standard sieve should be limited to 10% by weight for OPC, and 5% by weight for rapid hardening cement.
