Air Knocker

Category: Brands: Exen

Eliminate the blockage of powder by automation of hammering!
This product is used for the following applications:

  • Prevention of clogging in hopper in sewage sludge fuel production facilities
  • Prevention of blockage in dust hopper for dust collector in waste treatment plant
  • Prevention of blockage in the recycle fuel (capsule of compressed wood) supply hopper
  • Prevention of blockage in the glass cullet storage hopper
  • Elimination of clogging of livestock forage silo
  • Facilitation of ejection of silica gel
  • Elimination of adhesion of calcination product raw material on wall surface
  • Knocking off the ash in the recycling plant. Facilitation of ejection of aluminum powder
  • Prevention of adhesion in piping in pharmaceutical plant
  • Features

    The Air knocker (Indirect impact type) is a unique equipment in which the force of compressed air causes the piston to energetically strike the base surface, which eliminates the adhesion or clogging of powder. In addition, this knocker is excellent in safety and economics because it can be used only by air supply, and it can be used safely for powder that has a characteristic to show adhesion when receiving the centrifugal vibration.

    • Adjustable impact force
    • Relay piping allowing multiple units to be used simultaneously
    • Operating principle of Air knocker
    • Oil-free and environmentally friendly
    • Simple structure and high durability
    • Adoption of convenient push one joint (only for RKV20)
    • Various types of dedicated controllers for knockers are available
