11 6 Portland Cement Manufacturing US EPA

Typically these raw materials are obtained from open-face quarries but underground mines or dredging operations are also used Raw materials vary from facility to facility Some quarries produce relatively pure limestone that requires the use of additional raw materials to provide the correct chemical blend in the raw mix

limestone is mixed with which raw materials to produce clinker

In the manufacture of Portland cement clinker occurs as lumps or nodules usually 3 millimetres 0 12 in to 25 millimetres 0 98 in in diameter produced by sintering fused together without melting to the point of liquefaction limestone and aluminosilicate materials such as

Composition of cement engr psu edu

The materials are then fed through a kiln at 2 600º F to produce grayish-black pellets known as clinker The alumina and iron act as fluxing agents which lower the melting point of silica from 3 000 to 2600º F After this stage the clinker is cooled pulverized and gypsum added to regulate setting time

Investigation of Raw Material for the Manufacturing of

shale limestone may also be used in metallurgical and chemical industries The principal constituent of cement clinker is calcium oxide CaO which is obtained from naturally occurring calcium carbonate calcite which makes up approximately 75-80% of the raw materials mix used in cement clinker This primary calcareous raw material may
