The vertical mill circulation fan is used for the ventilation of the raw material mill system, and the centrifugal fan is commonly used. The blades of the raw material vertical mill circulation fan need to be treated with wear resistance. The medium of the cement mill circulation fan is a dusty gas containing clinker, which is highly abrasive. It is required that the impeller be treated with wear-resistant steel or surfacing, but the part that is separated from the medium must be treated with wear-resistant.

Features:

 

1. High internal efficiency can greatly save power, compared with other fans, it can save power by 10-30%.

 

2. The performance curve is flat, the adjustment range is wide, and the adjustability and controllability are good. When adjusting, the vibration speed of the bearing housing is small.

 

3. The advanced backward blade fan is selected, and the motor is not easy to be overloaded.

 

Sima fans can be used as centrifugal fans for cement lines with a daily output of 1,000-10,000 tons. They have the characteristics of wear resistance, high efficiency, low noise, good gas flow stability, and convenient maintenance.
