Dust Control Nozzles and Dust Control Systems

Monitor Engineering has been supplying dust control solutions to mining and industry for over 45 years and unlike most suppliers on the market today, we don’t only offer high pressure dust suppression systems.

We have a complete range of product solutions, high and low pressure nozzles and systems, air atomizing nozzles, spay bars, wetting and misting nozzles, filters, accessories, spray controllers and water cannons.

Each dust suppression system is unique and designed specifically around the  customer’s requirements.

Dust Control Considerations

  • Dust particle size
  • Spray nozzle drop size
  • Spray nozzle pattern
  • Spray angle
  • Operating pressure
  • Surface wetting
  • Nozzle placement
  • Water quality
  • Control options
If the drop diameter is larger than the dust particle diameter, the dust particle will follow the air stream around the drop (Shown left). If the diameters of the drop and dust particle are comparable, the dust particle will follow the air stream and collide with the drop (Shown right)

Dust Control Nozzles

At the heart of any dust control system is the nozzle. We have over 100 000 different nozzles and accessories operating conditions will determine which nozzle style and spray pattern will offer the best performance.

Hollow Cone nozzle features:

  • Circular ring of water
  • Large nozzle orifices that reduce clogging
  • Small drop size – generally smaller than other nozzle types
  • Typically used in locations where dust is widely dispersed
  • Most widely used for dust prevention

Flat Spray nozzle features:

  • Tapered-edge, rectangular or even spray pattern
  • Small – to medium – size drops
  • Typically used in narrow or rectangular enclosed spaces
  • Widely used for dust prevention
Flat Spray Nozzle

Flat Spray Nozzle

Full Cone nozzle features:

  • Round spray pattern
  • High velocity over a distance
  • Medium – to large – size drops
  • Commonly used when nozzles must be located a good distance away from the area where
    dust suppression is needed or to clear mechanical obstructions
  • Widely used for dust prevention

Air atomizing nozzle features: – (Nozzle mixes air and water to produce finest mist out of any type of nozzle)

  • Choice of spray patterns – round, full and flat
  • Very small drops
  • Commonly used to capture small dust particles in enclosed areas to minimize drift
  • Widely used for airborne dust suppression
Air Atomizing Nozzle

Hydraulic fine spray nozzle features: – (High or low pressure misting)

  • Hollow cone spray pattern
  • Very small drops
  • Commonly used to capture small dust particles in enclosed areas to minimize drift
  • Widely used for airborne dust suppression and operations requiring a light fog

Self-Cleaning Strainers

  • AWS and AWT self-cleaning strainers provide fine filter protection to ensure optimal spray system performance even when using poor quality water. A unique filtering process captures most contaminants and extends time between flush intervals
  • Large filter area captures most contaminants
  • Wide filtration range – 20 to 600 mesh (800 to 10 µm)
  • Minimal water flow used for cleaning/flushing so downstream water supply is not interrupted

Split-Eyelet Connectors

  • Use to install nozzles, gauges and hoses in piping
  • System quickly and easily
  • Eliminates body rotation within the flange when installing/removing nozzles
  • Eliminates need for taping holes and provides superior thread engagement to eliminate stripped threads
  • Reduces sediment and clogging – inlet extends into pipe
