Abrasion-resistant Ceramic Feeder

Product Announcement from FLSmidth


The exceptional abrasion resistance is due to our 2.54mm (0.100 inch) thick ceramic-coated bore, tungsten carbide rotor vane and shroud tips, and the tungsten carbide throat protection.

Additional design features include:

  • Cast body and end plates
  • Heavy-duty 8-vane, closed-end rotor
  • Air purged seals
  • Air gap between seals and bearings
  • Outboard sealed ball bearings
  • Up to 175°C (350°F) operating temperature
  • Capable of up to 15 psi differential pressure operation

FLSmidth’s heavy-duty rotary valve can handle abrasive materials in both pressure and vacuum pneumatic conveying systems. The valve can feed material at up to 0.26 cubic meters (9.1 cubic feet) per revolution, handle differential pressures up to 15 psi, and operate in temperatures up to 175°C (350°F).

This abrasion-resistant rotary valve has superior hard surfaces of ceramic tile and tungsten carbide which ensure long operating life.  Rotary valves are available in capacity ranges to meet most plant requirements for vacuum, pressure and general purpose applications
