  • Page 19: Operating Elements

    Operating Instructions 1-7D General 3.4 Operating elements The abrasive control handle is located on the machine handle and regulates the magnetic valve to control the flow of abrasive towards the blast wheel. The valve is hand-operated and can be set to each amount of abrasive throughput by changing the handle position.
  • Page 20 1-7D Operating Instructions General 3.5 Blast wheel The heart of the blast cleaning machine is the blast wheel which throws the abrasive onto the surface to be cleaned by using centrifugal force. The blast wheel is placed in a protective housing lined with replaceable wear plates.

  • Page 21: Separator

    Operating Instructions 1-7D General 3.6 Separator The abrasive separator is mounted to the end of the rebound plenum. It separates the abrasive from contaminants and feeds the cleaned abrasive back to the abrasive circuit. Fig. 3.4 Separator Separator seal Separator clamp A wire mesh is fitted to prevent any coarse contaminants from getting into the blast wheel.

  • Page 22: Abrasive Valve

    1-7D Operating Instructions General 3.7 Abrasive valve Between the abrasive storage hopper and the feed spout there is a valve incorporating a permanent magnet in order to control the abrasive flow towards the blast wheel. Any change in the opening of the magnetic valve causes the amount of abrasive fed to the blast wheel to change.

  • Page 23: Abrasive Sealing

    Operating Instructions 1-7D General 3.8 Abrasive sealing Magnetic seals are fitted to the front and the sides of the blast housing outlet. The blast head is surrounded by brush seals. The seals are employed to seal the blasting area in a way to avoid leakage of any abrasive.
