Raw materials Understanding Cement

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 and ferric oxide) Other supplementary materials such as sand, fly ash/pulverised fuel ash (PFA), or ironstone to achieve the desired bulk composition; Quarry management is an art; most quarries will probably have "good material

This stage includes the process of siege, crushing, and prehomogenization. Typical raw materials used for cement production have 85% cayenne, 13% clay or blackboard, and under 1% each of materials such as silica, alumina, and iron ore. These feedstocks are crushed into particles with a diameter of less than 20 mm and mixed with a prehomogenization pile [17]. (2) Clinker production. As shown in

The crushing stage involves breaking the raw materials into small fragments that vary in size between 6-14 mm. Machines called Crushers are used for this purpose. The drying stage is typical of the Dry Process. Drying of crushed materials is essential and is achieved by heating these materials (separately) at temperatures sufficiently high to drive out uncombined water. Heating is done in

Cement Manufacturing Process Phases Flow Chart

30/08/2012· Production of cement completes after passing of raw materials from the following six phases. These are; Extraction of raw material and crushing of material. Generally cement plants are fixed where the quarry of limestone is near bye. This saves the extra fuel cost and makes cement somehow economical. Raw materials are extracted from the quarry and by means of conveyor belt material

CEMENT RAW MATERIALS CemNet

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
