Cement mill is connected to this. A fan is connected to ESP and due to this force that is created by fan to draw the dust particles, the cement particles flow to the bucket elevator. From bucket elevator it is passed to a separator. A separator consists of two fans. As the name suggests separator is used for separating the materials into two classes, namely product and tailing. Product is the ...
The resistance of the air separating system is reduced by 30–35%, and the power of the circulating fan can be reduced by 40–45%, which has a certain energysaving purpose. The power consumption of the system can be reduced to less than 13 kWh/t after using the full external circulating raw material vertical mill. Roller Press Raw Material Final Mill System. Roller press is used for ...
These separators have a better separation efficiency due to the external fan and the cyclones. Comparison between cyclones and conventional separators: The diagram here below shows the specific surface (Blaine) produced in order to achieve a certain percentage of residue on 30µm (From Duda Cement Data Book).
