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 Prevention
Moisture content in the material is increased to prevent dust from becoming airborne.

Typical Operations:

  • Dumping
  • Transport
  • Transfer Points
  • Stock Piling
  • Reclaiming
Moisture is added directly to the material to prevent dust becoming airborne. Airborne dust particles are also captured by sprays during material unloading.

Dust Control / Suppression
Moisture is added to the air to capture dust particles that are already airborne. Most operations require both prevention and suppression to effectively control dust.

Typical Operations:

  • Conveyers
  • Transfer Chutes
  • Shearing
  • Continuous Mining
  • Crushing and Screening
  • Dryers
  • Packing / Filling
After material has been dumped into the hopper, sprays are used to suppress the airborne dust.

After material has been dumped into the hopper, sprays are used to suppress the airborne dust.

Moisture is added to the material to prevent dust as it is transferred from the hopper car to the hopper bin. Sprays are also used to capture airborne dust as the material moves down the conveyor line.

New Guide on Dust Control Using Spray Technology Now Available

Dust prevention and suppression using wet dust control systems are addressed in a new in-depth guide published by Spraying Systems Co. The 20-page guide provides an overview of operations ideally suited to using spray technology to control dust and detailed information on how to configure a system and optimize performance. The guide addresses critical issues in dust control system specification including type of material generating the dust, particle size of the dust, dust location, availability and quality of water and more.

One section in the guide is devoted to spray nozzle selection. Spray angle, operating pressure, surface wetting and nozzle placement and positioning are discussed. Various nozzle types are reviewed and usage guidelines are provided. Additional sections in the guide cover options for system control, tips for spray system optimization, common performance problems and possible solutions, maintenance guidelines and more.

A Guide to Spray Technology for Dust Control is available upon request from Monitor Engineering. There is no cost for the guide. Click here to request the guide.
