Apr 13, 2020 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 C. During this process, these materials partially fuse to form nodular shaped clinker by broking of chemical
