Manufacturing Of Portland Cement – Process And Materials

Apr 13,   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  to  ⁰c. during this process, these materials partially fuse to form nodular shaped clinker by broking of chemical.
