Cement manufacturing - raw materials - Understanding Cement
Cement manufacturing - raw materials. If you happen to be a geologist, the raw materials quarry is probably the most interesting part of a cement works, maybe unless you view the clinkering process as igneous rocks in the making. The most common raw rock types used in cement production are: Limestone (supplies the bulk of the lime) Clay, marl or shale (supplies the bulk of the silica, alumina ...

CEMENT RAW MATERIALS - International Cement Review
The raw materials used in cement manufacture are extracted in large quarries, typically with outputs of up to, or over, 2.5 million tonnes per year. Typically about 1.65 tonnes of limestone (1.5 to 1.8 tonnes) and 0.4 tonnes of clay are quarried for each tonne of cement produced. Large reserves of feedstock, particularly of limestone, are required to provide security of supply and these are ...

Cement manufacturing - components of a cement plant
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.
