SPCC decided to upgrade finish mill #2 with a new Roller Press circuit. An upgrade to 160tph of Portland Cement was required with a fineness of 3200cm2/g (Blaine). Studies of the mill circuit showed that the existing circuit can handle an extra capacity of at least 50tph. The process design pro- posed by KHD Humboldt.

Rawmill - Wikipedia

A rawmill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill. The rawmilling stage of the process effectively defines the chemistry (and therefore physical.
