A cement manufacturing process is well suited for co-processing of wastes from different sources. Wastes need to be converted into alternative fuels and raw materials (AFRs) through the pre-processing operation and then utilized to substitute fossil fuels and raw materials used in the cement process.
Cements may be used alone (i.e., "neat," as grouting materials), but the normal use is in mortar and concrete in which the cement is mixed with inert material known as aggregate.Mortar is cement mixed with sand or crushed stone that must be less than approximately 5 mm (0.2 inch) in size. Concrete is a mixture of cement, sand or other …
Extraction and Preparation of Raw Materials. The main raw materials (limestone, clay chalk or basalt) are quarried from natural rocks. They are crushed and transferred to pre-blending storage where other substances (such as sand, iron ore, bauxite, shale, slag, fly ash) are added to get the desired chemical composition.
The manufacturing of cement involves two processes known as the wet process and the dry process, depending upon whether the mixing and grinding of raw materials is done in a wet or dry state. Cement Manufacturing Plant

2 CEMENT MANUFACTURING PROCESS A cement production plant consists of three major processes such as quarry and raw material preparation, clinker production and cement grinding and distribution [2]. During raw material preparation first, limestone and other raw materials are extracted using drilling and blasting techniques.
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. ... However, reading an article or two is perhaps not the best way to get a clear picture of a complex process like ...
