  • The basics
  • Design

Key benefits

  • Fan efficiency up to 80%
  • Designed for the harsh conditions of the cement industry
  • Simple installation – single suction type requires only one suction pipe connection
  • Rigid support in elevated concrete foundation
  • Optimal rotor stability and thermal endurance
  • Heavy-duty design
  • Unique FLSmidth bearing housing with conical grease valve
  • Minimal maintenance

How they work

These medium-pressure fans are suitable to generate a flow of clean or dust-laden, non-abrasive gas or air. Flow rate: up to 400 m3/s; pressure: up to 9,000 Pascal.

Available in several sizes, the MT fan can withstand continuous operation at flow temperatures up to 400°C and 450°C for short periods.

Typical applications

  • Kiln and raw mill filter fan (for raw meal/clinker production, and process and pollution control – ESP and bag filter)
  • Cooler excess air filter fan (for clinker production, and process and pollution control – ESP and bag filter)
  • Bypass filter fan (for clinker production, and process and pollution control – ESP and bag filter)
  • Cement mill filter fan (for cement grinding, and process and pollution control – bag filter)
  • Cement separator filter fan (for cement grinding, and process and pollution control – bag filter)
  • Bleed air fan (for raw meal and clinker production, and emergency cooling for bag filters)
  • Combustion air fan (for clinker production – U type heat exchanger)
  • Hot gas and air booster fans (for raw meal production, coal and cement grinding – to transport hot gas to grinding processes)

Optimal rotor stability

The shrouded impeller with S-shaped blades ensures optimal rotor stability and low risk for dust build-up. The impeller is bolted to a cast hub. The hub and impeller are dynamically balanced to ensure vibration-free operation. Access doors make it easy to inspect the impeller. 

Heavy-duty design

Because of the fan’s heavy-duty design, no emergency (barring) drive is required in the event of power cuts.

Self-aligning roller bearings

All MT fans are fitted with spherical, self-aligning roller bearings. The unique FLS bearing housings with conical grease valve ensure optimal lubrication and eliminate problems by overfilling. The bearing housings are bolted to a heavy base frame grouted in the concrete foundation. A cooling disc on the shaft prevents overheating of the bearings.

Motor power transmission

Motor power is transmitted by a flexible coupling, V-belts (max. 250 W) or a gear unit.
