Manufacturing of Portland Cement Process and Materials

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 by broking of chemical bonds of

Re: target particle fineness leaving raw mill. Hi Branco, The way to characterise the fineness of any powder is to determine the sieve residue at 2 different particle sizes and use that to determine the Rosin Rammler distribution. Kiln feed with a 15% residue on a 90 micron sieve would typically have a Rosin Rammler position or characteristic grain size of around 50 microns.
