The manufacture of Portland cement is a complex process and done in the following steps: grinding the raw materials, mixing them in certain proportions depending upon their purity and composition, and burning them to sintering in a kiln at a temperature of about 1350 to 1500 ⁰C. During this process, these materials partially fuse to form nodular shaped clinker …

Single headed grinders. These grinders have a central shaft that drives a single head. On smaller machines the head comprises one disc, often with a diameter of 250 mm. Larger machines can take three discs in a range of diameters, generally up to 250 mm each, which gives them a grinding width of 550 mm or more.

The working principle is that cement is removed from the mill before over-grinding has taken place. The cement is then separated into a fine fraction, which meets finished product requirements, and a coarse fraction which is returned to mill inlet. Recirculation factor, that is, the ratio of mill throughput to fresh feed is up to three.
