There are three types of cement manufacturing processes - wet, semi-dry and dry processes. In the wet/semi-dry process, the raw materials are produced by mixing limestone and water (called slurry) and blended with soft clay. In dry process technology, crushed limestone and raw materials are ground and mixed without addition of water.
