CFH-CD process rotary feeder

High-pressure compact feeder – cutting device

The CFH-CD version with cutting function is used primarily for the feeding and discharge of powders and agglomerated products underneath discharge containers. The special design of the rotary feeder increases process safety and facilitates use at differential pressures up to 3.5 bar (g).


As well as all the characteristics of the CFH valve, the CFH-CD also offers several further highlights:

  • Available in three sizes (500/630/750)
  • Generally more robust design to ensure high torque and therefore also the cutting function:
    - Robust aluminum housing with stainless steel cutting function
    - Reinforced rotor (shaft, bridges, spacers, bearing)
    - Reinforced bearing plates construction (bearing, sealing)
  • Wear-resistant cutting edges thanks to stellite welding on the rotary feeder bridge
  • No removable blades used on the bridges
  • Automatically changing rotation direction (rotor switches to the opposite direction at a defined torque to ensure that agglomerated product does not cause blockages)
  • Process heating with temperature monitoring
  • Valve can be started with full bulk material column
