Performance Enhancer for Portland Limestone Cement (PLC)

In practice, portland-limestone cement is ground to a higher fineness compared to portland cement. An increase of Blaine in the range of 100cm 2 /g is necessary to compensate for the strength reduction resulting from the addition of 1% limestone. 3. The mill type and process system play an important role.

Cement mill Residue Page 1 of 1

Re: Cement mill Residue. Hi Jatinder, You could increase the speed of your separator rotor, i.e. increase recirculation load. But you may then experience an excessively high blaine value. The best way to make a balance on mesh passing and blaine is to play around with feed tonnage and separator rotor speed. Branco. Reply
