Cement mill - Wikipedia
However, particle size distribution is again a problem, and roll presses are now increasingly popular as a "pre-grind" process, with the cement finished in a single chamber ball mill. This gives good cement performance, and reduces energy consumption by 20-40% compared with a standard ball mill system.
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.
Particle Size Distribution 3
x = size in microns m = slope of the plot a = size at 36,8% of particles retained (36,8 is the ratio 100/e and e is the Neper number - 2,718) - From the equation hereabove, we obtain: - Considering that we take the logs on both sides of the equation, we have: and: The Cement Grinding Office
