fan mill coal

Coal Mining Ventilation Fans - Industrial Coal Fans | New York .Both deep shaft and surface mining operations use a variety of NYB fans. Non-sparking below-ground applications use both axial and centrifugal designs for ventilation and safety exhaust-and-supply systems. Processing and crushing of coal often take place at the power plant or mill where the coal will be used as mill coal,Coal Mill Ventilation - ClarageClarage's years of fan knowledge gives us the unique ability to design a fan for any coal mill application. Be it our HMF, special Coal Mill Exhauster or a simple backward inclined wheel for general ventilation, we have it all. With over 140 years of experience, we have been installing fans in coal mills since the beginning.
