EB-water spray system

The EB-water spray system is an advancement of the conventional cutting track water spray system. The nozzle sits well-protected in a chamber on the back of the pick block. According to the function of a jet pump, the EB-system absorbs the dusty air arround the pick block. Thereby you get an active dust absorption. Further the full water spray is expanded with air. So you get a water-air spray with a very fine dropplet spectrum. That addionally ensures high efficient dust absorption combined with high effective explosion prevention.

Advantages of KRUMMENAUER EB-water spray system:

  • ATEX certified at only 20bar water pressure (nozzle-Ø 0,7 mm)
    • Reduction of water demand by about one third
    • Reduction of infrastructural costs for high pressure units
  • Active dust absorption
  • Nearly free of maintenance
  • Self-purification of air suction channels
  • Easy-to-change and -clean nozzle
  • Cutting speeds up to 3,5 m/s
The high safety standards of the EB-system have been successfully proven at the DMT test station under ignitable methane-air mixture. KRUMMENAUER EB-water-spray system is the only system which faced up to this realistic test conditions of the DMT. Thereby the EB-system is the reference for all cutting track water spray systems. The test results had been confirmed by underground measurements. Pick blocks with EB-water spray system are available for all shearer drums and cutting heads.
