A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

Cement mill Building is one of the most vital part of cement plant where Cement is produced by grinding clinker, additives like gypsum and Flyash. Ball mill is used to grind the Clinker. The Cement mill building comprises of three RCC structures - Cement mill feed hopper, Cement Mill building and Flyash silo supporting structures.

Cement is stored in 4 x 7500 T cement concrete silos. A sophisticated bulk cement terminal (which subscribes to all environmental norms) dispatches cement in bulk form to RMC and asbestos plants. The terminal also has a modern Italian make Ventomatic packer to pack cement in 50 kg paper bags to service customers on the island.

The first step is to quarry the principal raw materials, mainly limestone, clay, and other materials. After quarrying the rock is crushed. This involves several stages. The first crushing reduces the rock to a maximum size of about 6 inches. The rock then goes to secondary crushers or hammer mills for reduction to about 3 inches or smaller.

The answer is the cement industry. Limestone plays two major roles in the cement manufacturing process, one is used as a raw material for cement clinker, and the other is used as a cement admixture. Limestone is one of the key raw materials of cement clinker. Around 80-90% of the raw material for the kiln feed is limestone.

During the process, due to the rotary motion of the cement kiln, the materials aggregate into lumps or nodules, known as clinker. Clinker then falls out of the kiln into the cooler where it is rapidly cooled, then stored in a clinker silo. The third stage in the process involves grinding clinker into a fine powder, that is, into cement.

The result of this process is called clinker, which are rounded nodules between 1mm and 25mm across. Than the clinker is broken down to a fine powder in a cement mill and mixed with gypsum to create cement. Gypsum plays a very important role in controlling the rate of hardening of the cement. It is introduced during the final grinding process.
