 · 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 .

Raw Mill Process Raw mill is used for grinding and drying of raw material. It contains rotating table on which four rollers are pressed by hydraulic pressure with a certain clearance required for grinding. The ground product is called raw meal. The purpose of this equipment is drying and grinding of cement raw material.

Summary of production process. Cement is typically made from limestone and clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blended raw material is called the 'raw feed' or 'kiln feed' and is heated in a rotary kiln where it reaches a temperature of ...

 · The clinker and the required amount of gypsum are ground to a fine powder in horizontal mills similar to those used for grinding the raw materials. The material may pass straight through the mill (opencircuit grinding), or coarser material may be separated from the ground product and returned to the mill for further grinding (closedcircuit grinding).
