CEMENT RAW MATERIALS

The raw materials which supply cement works, and which may be required in quantities of over 4,000 tonnes per day, must be thoroughly proven if the plant is to run successfully Consistent quality feed is required and an extraction plan must be made to ensure that a uniform flow of raw material will always be available to the kilns...

Clinker (cement)

In the manufacture of Portland cement, clinker occurs as lumps or nodules, usually 3 millimetres (012 in) to 25 millimetres (098 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...

Cement manufacturing

Cement is typically made from limestone and clay or shale These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions This blended raw material is called the 'raw feed' or 'kiln feed' and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C...
