Size Of Cement Mill

grinded particle size of cement

However, particle size distribution is again a problem, and roll presses are now increasingly popular as a "pregrind" process, with the cement finished in a single chamber ball mill. This gives good cement performance, and reduces energy consumption by 2040% compared with a standard ball mill system.

Portland Pozzolana Cement (PPC)

Concrete mixtures made from PPC typically reduce the water needed by 5% to 10% over the concrete made from OPC. The specific gravity of PPC is much lower than that of OPC; therefore, 100# of fly ash has a much greater solid volume than the same weight of OPC. In PPC concrete, the cementitious materials (cement and fly ash) volume is higher.
