Clinker Production Clinker Plant Cement Plant Equipment

After the raw material is preheated and precalcined, the next step is clinker manufacturing. In the rotary kiln, the carbonate is further rapidly precalcined and a series of solid phase reactions occur to form minerals in the cement clinker. As the temperature of the material increases, the mineral becomes a liquid phase and reacts to form a large amount (clinker).
