Cement Clinker Processing Plant

Cement Clinker Processing Plant

The main raw materials used in the cement manufacturing process are limestone, clay, sand, shale and iron ore. Limestone is usually mined on site while the other minor materials may be mined either on site or in nearby quarries. Another source of raw materials is industrial by-products. The use of by-product materials to replace natural raw materials is a key element in achieving sustainable development.

Cement Clinker Grinding Machine

Cement grinding is the last process of cement production line, also the most power consuming process. Its main function is to grind the cement clinker into the appropriate size and a certain particle size distribution, which is for increasing the size of its hydration, accelerating the hydration rate and meeting the coagulation, hardening requirements.

Cement Clinker Dry Process

In the dry process, each raw material is proportioned to meet a desired chemical composition and fed to either a rotating ball mill or vertical roller mill. The raw materials are dried with waste process gases and ground to a size where the majority of the materials are less than 75 microns. The dry materials exiting either type of mill are called "kiln feed". The kiln feed is pneumatically blended to insure the chemical composition of the kiln feed is well homogenized and then stored in silos until required.
