Cement Manufacturing—Technology, Practice, and Development
In the wet and semi-wet process, the raw materials are mixed and made into a slurry. This slurry is then ground to the defined size. The raw meal or the raw material slurry is finely ground and homogenized in raw meal silos or basins. This helps to achieve the uniform chemical composition required for manufacturing desired quality of cement.
Cement Clinker Quality Control
During normal production process, the clinker is always calcined in a fixed temperature range. According to the fluctuation of raw meal composition, the calcination temperature of clinker is generally between 1350℃ and 1450℃. If the temperature in the kiln is too low, it is easy to produce underfired clinker.
