Cement vertical mill, also called roller mill, is another raw mill commonly used in cement plants. Compared with the cement ball mill, it has a great difference in structure, grinding principle, process layout, automatic control, and energy consumption, which play an important role in the modern cement industry. High Grinding Efficiency.

Colored Cement: the colored cement is manufactured by mixing the pigment with the ordinary Portland cement. Its production mainly adopts the staining method and calcination method, the latter of which has a durable color but a high production cost. This cement is widely used in the surface coating of floor, wall and various buildings.
