One mill and one silo may be reserved for OPC, with the rest for whatever type(s) of cement (PPC/BFSC) are to be made. If a cement plant is making both PPC and BFSC (which is quite possible) groups of mills will be reserved for each category so as to avoid changes of settings, cleaning of silos to avoid contamination, etc. 1.11.1. Dispatches
Both the cement ball mill and the cement roller press have their own advantages and disadvantages, but in actual production, the cement roller press has the advantages that the ball mill does not have, mainly reflected in the following points. High grinding efficiency, increasing production and energy saving.
Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.
