M-Flow Main Fans

The main underground ventilation system is crucial to safety and efficiency in mining operations, being responsible for removing contaminated air from the main galleries and ensuring the entry of fresh air. The fans used for this application are predominantly exhaust fans, designed to pull stale and polluted air from inside the mine, creating a flow that allows clean air to enter through other accesses.

Characteristics and Technical Considerations

High Flow and Pressure

Exhaust fans used in primary underground ventilation need to operate at high flow rates and often under high pressure conditions. FanTR has developed axial exhaust fans capable of reaching pressures that were previously only possible with centrifugal fans. This innovation allows the use of axial fans that are more economical, efficient and easy to maintain, without compromising the performance required for underground environments.

Erosion and Corrosion Resistance

The underground environment of a mine is highly corrosive and erosive due to the contaminated air, which can contain water, ore debris and rock particles. The propulsion assembly of the exhaust fans - rotor, blades and spinner - must be made of materials resistant to these extreme conditions.

FanTR's research and development center has created an exclusive line of rotors for axial exhaust fans that offer unparalleled resistance to erosion and corrosion, surpassing even rotors made of stainless steel. This ensures greater durability and less need for maintenance, even in challenging environments.

Adapting to Topography and Mine Operation

The topography of the site and the operation of the mine are determining factors in the sizing and installation of the main ventilation system. Often, a system combining several hoods in parallel is required to meet the specific demands of the point of operation. This configuration must be carefully adapted to the local topography and the mine's operational needs.
