the extraction and preparation of raw material – a process covering the stages from raw material quarrying to feeding the raw meal into the preheater. The purpose of optimum raw material preparation for the cement manufacturing process is to supply the downstream burning process with a raw meal whose quality and homo-geneity assures the economi-

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.

Since a form of calcium carbonate, usually limestone, is the predominant raw material, most plants are situated near a limestone quarry or receive this material from a source via inexpensive transportation. The plant must minimize the transportation cost since one third of the limestone is converted to CO2 during the pyro-processing and is subsequently lost. Quarry operations consist of

The proportioning of cement raw materials is not all the same but should be determined according to the actual situation. The proportion of raw materials of different specifications of cement is also different. Generally, the proportion of components in cement raw materials is 67-75% limestone, 10-15% clay, 0.5-1.5% iron ore and 8.5-11% coal.
