Mine Main Fan
The main ventilation fan in a mine is used to meet the ventilation needs of the entire mine. We can calculate the air volume and negative pressure values at each mining stage, and select the appropriate main ventilation fan by matching the operating points and fan performance curves at each ventilation stage of the mine. Our main ventilation fans have a design life of more than 20 years and can provide optimal energy-saving performance throughout their entire lifespan.
The mine main fan is responsible for the ventilation needs of the entire mine.
How to select the mine main ventilation fan?
It is necessary to calculate the required air volume and negative pressure value of the mine, and match the operating point of the ventilation stage with the performance curve of the mine main fan.
What are the types of mine main fans?
Mining main ventilation fans are classified into two types according to their structure: axial flow type and centrifugal type. Axial flow type is the commonly used type of mining main ventilation fan.
How to customize a mine main ventilation fan?
Mining main ventilation fans are customized by combining "hub ratio + number of blades + blade angle + rotation speed".
Can a mine main ventilation fan change the airflow direction?
Yes, the main ventilation fan in a mine changes the direction of airflow by changing the rotation direction of the impeller. Reversing the airflow accounts for 60% of the fan's air volume.
