Raw materials

Technically a cement producer can have almost complete control over clinker composition by blending raw materials of different compositions to produce the desired result In practice however clinker composition is largely determined by the compositions of the locally-available raw materials which make up the bulk of the raw meal

Cement Manufacturing Process Phase 1: Raw Material Extraction Cement uses raw materials that cover calcium silicon iron and aluminum Such raw materials are limestone clay and sand Limestone is for calcium It is combined with much smaller proportions of sand and clay Sand clay fulfill the need of silicon iron and aluminum

The cement kiln

However new cement kilns are of the 'dry process' type Dry process kilns In a modern works the blended raw material enters the kiln via the pre-heater tower Here hot gases from the kiln and probably the cooled clinker at the far end of the kiln are used to heat the raw meal As a result the raw meal is already hot before it enters the

The raw material preparation stage of cement manufacture results in the production of a rawmix that is in a suitable state for feeding to the kiln in which it is converted by heat The raw meal mixer was designed by William Gilbert and David putting the emphasis on exact weighing of raw materials at the raw mill Of course this
