The raw materials are crushed to around 20-25 mm size and the proportioned raw materials are ground in a ball mill in dry condition to a very fine powder. The resultant product is called raw meal and is stored in concrete silos where it is pneumatically homogenized to get a uniform product. 2. Clinker production
Tight control of every step in production process is of outmost importance for achieving the maximum efficiency and quality of cement. From stock pile management, production of raw meal, preparation of kiln feed and the production of clinker right through to the final mixing of the end product the control is driven by the elemental, mineralogical composition and particle size analysis.

Cement Production: Raw Meal Production in Steps Perfectly mixed, accurately fed without pulsation, and precisely weighed. The key word is quality! And this quality is achieved during cement production with exactly matched process steps. In the first stage, the raw meal is produced, as described below.
5) Raw meal homogenizing silo The cement manufacturing machine is designed with one Φ16m homogenizing silo for blending and storing the raw meal, so that the raw meal fed into the preheater can reach the design and production requirements. The storage capacity of the silo is 7,500t.
The red mud was mixed with other raw materials, such as limestone, schist, Milos sand, ironferous sand and bauxite, in appropriate proportions in order to produce the raw meal to be tested for the production of Portland cement clinker ((PC) R/M).
