The production process consists of grinding the raw materials to a fine stage, blending them to a uniform composition and heating them to the point of incipient fusion when the cement compounds are formed. the white portland cement is the product obtained by cooling and grinding the clinker thus formed with gypsum to a fine powder.
The cement industry has for some time been seeking alternative raw material for the portland cement clinker production. the aim of this research was to investigate the possibility of utilizing iron ore tailings iot to replace clay as alumina-silicate raw material for the production of portland cement clinker. for this purpose, two kinds of clinkers were prepared one was prepared by iot the ...
The following demonstrates a calculation for the determination of the proportions of the raw material components to be used for producing a clinker of a required potential composition of minerals. example 2.10. given are two kinds of raw materials, limestone and clay, the chemical composition of which is shown in table 2.9., column 1, and 2.
They are called cement rocks because they can be used as a single raw material for the cement manufacturing process. 3. gypsum it is generally added in very small amounts about 2 by weight to the burnt cement called clinker after it is taken out from the kiln and before it is sent for grinding.
