why bauxite is used to manufacture cement clinker. Ball mills are used primary for single stage fine grinding, regrinding, and as the second stage in two stage grinding circuits. According to the need of customers, ball mill can be either wet or dry designs.

History. The method of making cement from limestone and low-silica bauxite was patented in France in 1908 by Bied of the Pavin de Lafarge Company.The initial development was as a result of the search for a cement offering sulfate resistance. The cement was known as "Ciment fondu" in French.

For producing OPC, clinker and gypsum are used and for producing Portland [Pozzolana] Cement ("PPC"), clinker, gypsum and fly ash are used. In the production of Portland Blast Furnace Stag Cement ("PSC"), granulated blast furnace slag from steel plants is added to clinker Block diagram of cement manufacturing process: 1 .

Lime Component Limestone: Common forms of calcium carbonate used as raw material for cement manufacturing are limestone and chalk.Limestone is of predominantly fine grained crystalline structure, its hardness is between 1.8 to 3.0 of the Mohs scale of hardness and specific gravity 2. To 2.8. Limestone usually contains admixtures of clay substance or iron compounds, which influences its color.
