Cement manufacturing ore

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.
