The raw mill is either a Ball mill with two chambers or Vertical roller mill with inbuilt classifier. The hot gases from the pre heater enter the mill and are used for drying material in the mills.

From mine to cement. Basic raw materials required to manufacture cement is Limestone (90 - 95%), Clay/Marl, Shale, Bauxite, Iron Ore/Laterite/Mill Scale. The Limestone from Mines is brought to the Crusher through dumpers where the size reduction takes place to the extent of 70 - 90 mm max; transported through belt conveyor. Online Cross Belt ...

Cement is a crucial building material used in construction. The Cement manufacturing process involves the extraction and preparation of raw materials, such as Limestone, clay, shale, iron ore, and Gypsum. These materials are crushed, ground, and blended to form a raw meal, which is then heated in a kiln at high temperatures.
