Cement making process
2.Wet cement process. The manufacture of cement is a very carefully regulated process comprising the following stages: 2.1. Quarrying - a mixture of limestone and clay. 2.2. Grinding - the limestone and clay with water to form slurry. 2.3. Burning - the slurry to a very high temperature in a kiln, to produce clinker.
