3. Grinding: The clinkers as obtained from the rotary kiln are finely ground in ball mills and tube mills. During grinding, a small quantity, about 3 to 4 per cent, of gypsum is added. The gypsum controls the initial setting time of cement. If gypsum is not added, the cement would set as soon as water is added.
During the grinding process from raw material to raw meal as well as during fine grinding of burnt clinker with additional primary components or additives, monitoring and control of grinding grade is crucial for assurance of cement quality and production efficiency.
Burning and grinding operations of cement The grinding of clinkers in modern plants is carry out in the cement mill which contains chromium steel balls of various sizes. These balls roll within the mill and grind the mixture which is collect in a hopper and taken in the bucket elevator for storage in silos.
About half of the production cost in the cement industry is energy consumption – primarily during burning and grinding. Prompt and precise control of cement grinding and material testing not only avoids energy and cost intensive overgrinding, it also allows cement grade changes in a very short time within one plant with only small amounts of out-of-spec material.

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 …
Ordinary portland cement, the most widely used standard variety, is made by grinding up limestone and then cooking it with sand and clay at high heat, which is produced by burning coal. the process produces carbon dioxide in two different ways from the burning of the coal, and from gases released from the limestone during the heating.
