Manufacture of cement. There are four stages in the manufacture of portland cement 1 crushing and grinding the raw materials, 2 blending the materials in the correct proportions, 3 burning the prepared mix in a kiln, and 4 grinding the burned product, known as clinker , together with some 5 percent of gypsum to control the time of set of the cement.
The quality of cement clinker is directly related to the chemistry of the raw materials used. Around 8090 of raw material for the kiln feed is limestone. Clayey raw material accounts for between 1015, although the precise amounts will vary. Magnesium carbonate, which may be present in limestone, is the main undesirable impurity. The level

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. Cement manufacturing begins with quarrying operations in which limestone in mines is quarried and brought to crusher for crushing.
Raw material proportioning. The homogenized limestone and claysilcastone along with other raw materials like sand and iron ore are reclaimed into separate feed bins. The proportional ratio of the raw materials is fixed using raw mix design and is determined from the chemical analysis of the raw materials.
Raw mill is generally called cement raw mill, raw mill in cement plant, it refers to a common type of cement equipment in the cement plant.In the cement manufacturing process, raw mill in cement plant grind cement raw materials into the raw mix, and the raw mix is sent to the cement kiln to make cement clinker, next, clinker and other admixtures will be ground into finished cement by cement mill.

The cement industry processes requiring fine grinding are rawmix preparation, fuel preparation and grinding of clinker to make cement. All three may require a preliminary crushing stage. In the case of raw materials, attempts have always been made to minimise the amount of crushing needed by extracting the rock in the finest possible state.
Similar to the dry process, materials also need to undergo quarrying, primary crushing, secondary crushing, proportioning and grinding in the raw materials preparation stage of the wet process. The biggest difference between the two methods is that in the wet process, water is usually required as a process media added in the raw mix to form slurry.
