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)

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

Hollow Cone Nozzle

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

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

Full Cone Nozzle

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

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.
