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 ...

RAW MATERIALS IN CEMENT PRODUCTION
The only common feature in all cement production plants is the difficulty of grinding the source material as the material is hard enough and has high abrasiveness. That is why high quality grinding balls with high hardness over the entire section are used during grinding materials in tube mills in this industry.
