Grinding of cement raw material – material separation in cyclones. The cement raw material mixtures are ground, dried, and classified in the Pfeiffer vertical roller mill. For drying the material, hot gases are directed into the mill. Product fineness can be adjusted within a wide range ( to mm).
At the same time, there is less sewage discharged in the dry process cement production. It is conducive to environmental protection. Nowadays, we call the production line with preheater and precalciner as the new dry process cement production line, which is the development direction of dry process cement manufacturing in the future.
Cement Vertical Roller Mill.
