Get PricePortland Cement Manufacturing Process Description17 Portland cement is a fine powder, gray or white in color, that consists of a mixture of hydraulic cement materials comprising primarily calcium silicates, aluminates and aluminoferrites. More than 30 raw materials are known to be used in the manufacture of portland cement, and these
Get PriceThe cement manufacturing plant mixes clinker and gypsum to produce cement. The proposal is to add up to five percent finish mill additives during the cement manufacturing process. These additives are softer than the clinker they replace. Therefore, less energy is used in the grinding and mixing of clinker, gypsum and mill additives.
Get PriceIn the manufacture of Portland cement, clinker occurs as lumps or nodules, usually 3 millimetres ( in) to 25 millimetres ( in) in diameter, produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.
