dehydration of gypsum is taken into consideration for processes that contain gypsum. As the vertical roller mill is much more energy efficient than a ball mill, the amount of heat generated from the grinding is less, and the dehydration of the gypsum is lower. A good circulation of the process air is mandatory. This can be achieved by returning the ventilation air to the mill in order to keep ...

Cement grinding Vertical roller mills versus ball mills • Increase dehydration of gypsum by adding more heat to the mill system • Addition of a more reactive form of gypsum. In order to ensure an adequate dehydration of the gypsum also when grinding cement in a vertical roller mill, the layout, as shown in Figure 7, is prepared with.
The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 3040% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time delay characteristics also dynamics changes within 24 minutes. The fast dynamics necessitate closer attention to the process condition and taking ...

In vertical roller mills, the air volume in the mill is determined by the material feed rate. The air volume can be controlled by adjusting the power of the circulating fan of the mill or the opening of the exhaust fan at the kiln tail. If the air volume is too large, the pressure difference in the mill and the current of the main motor will decrease, the thickness of the material layer will ...
