Dry, semidry, semiwet and wet processes are the four main process routes that are used for the production of cement. Dry processes are considerably more energy efficient but the choice of technology mainly depends on the state of raw materials.
Limestone and other raw material. The second major component in the production of cement is the cost of raw materials. The primary raw material that's used is limestone. Raw materials account for 30%–40% of the cost of sales. Cement plants are generally loed near limestone quarries because limestone can't be transported long distances.
Clinker is the raw material used to manufacturing the cement. The clinker plant comprises of feed pre crusher, feed hopper, table feeders, ball mill, packaging cement plant and material handling equipment.

Cement is manufactured by blending different raw materials and heating them at a high temperature in order to achieve precise chemical proportions of lime, silica, alumina and iron in the finished product, known as cement clinker.
Cement production is a precise and controlled activity involves the transformation of the raw materials through a series of steps into a consistent powdered ...
A typical process of manufacture consists of three stages: grinding a mixture of limestone and clay or shale to make a fine "rawmix" (see Rawmill);; heating the rawmix to sintering temperature (up to 1450 °C) in a cement kiln;
