Dust Suppression for Mine Sites
Good management of dust is essential to the wellbeing of your employees and the environment. CoolMist Systems Australia offers high pressure misting systems and mist cannons that are proven effective, safe and environmentally friendly dust suppression solutions.
Dust has a significant health and environmental impact associated within many areas of the mining industry. Any dust, no matter how small, poses a threat to workers health, as well as having a significant impact on the running costs of machinery on a mine. It is the most common health and safety issue facing management and workers.
Unique solutions must be found to address the environmental and human impact that dust and temperature have. On a mine site this can be from the quarry to the conveyor belts to the loading bays, including crushers, mills and separators, and stockpiles which all contribute to a high generation of dust from these facilities.
Dust Control Systems
CoolMist Systems Australia design, supply and install high pressure misting systems tailored to suit your site’s needs. These high-pressure systems are the key to effective dust suppression. Our systems are designed to target breathable and fugitive dust particles from 3 to 500 microns. The Dust Suppression Systems can be installed to combat general airborne dust over a large area or they can be installed at the point where dust generation occurs. When open spaces require dust suppression, and a static line system is not a practical option, the solution may lie with the introduction of an AJet® Mist Cannons to the site.
Dust Suppression Solutions - Tailored for your site
Working with you we will customise an effective dust suppression system to your unique facility rather than using a one size fits all approach. We’ll design your system so that fog is concentrated where it is needed most, capturing and suppressing the dust without wetting the process material, your equipment and facilities. Inside or out our systems combat dust over large areas or they can be installed at the point where dust generation occurs.
We supply the total package including installation and commissioning, locally and interstate to help you meet environmental air quality standards and protect workers’ health.
AJet® Mist Cannons - Powerful and Robust Dust Control
Using exclusive technology, AJet® Mist Cannons (also known as fog cannons) have been engineered for efficient and effective dust suppression in harsh environments like mining.
The hydraulic machines are robust, versatile and simple to operate with remote control and are ideal for both indoor and outdoor use. Manufactured in standard modules, AJet® Mist Cannons are available in a basic configuration and upgraded with various components such as rising boom, trailer and generator. The range includes pole mount, wall mount, roof mount, self-contained mobile machines, trailer, skid or crawler mounted or alternatively fixed or mounted onto any vehicle.
Implementing dust control with high-pressure mist systems or fog cannons will also result in a longer lifespan of the machinery that is used on site as dust particles will not invade the moving parts of the machinery. These dust suppression methods ensure that there is no moisture accumulation on the equipment and machinery, and neither on the environment, which means no puddles and therefore no mud.

What is industrial dust?
Dust consists of tiny particles of dry, solid matter. Industrial dust is a by-product of activities such as earthworks, excavation, blasting, transportation, product processing, manufacturing and waste and recycling processes. Dry climatic conditions and wind can intensify dust generation.
Dust has a significant health and environmental impact associated within many areas including mining, construction, demolition, manufacturing, and agriculture industries.
Many operators are challenged daily as dust particles pose serious health issues, increased maintenance cost and down times, loss of material, product quality and reduced productivity and regulatory compliance.
Why is dust control important to industrial operations?
Without proper dust control, your workers are exposed to harmful dust, particulates, and contaminants in the air. Airborne dust particles cause breathing difficulties, skin and eye irritation, and serious respiratory diseases. Prolonged exposure to these dust particles can significantly affect the health and well-being of your workforce.
Dust can damage and interfere with the functionality of equipment like conveyors and their components, plant and equipment, motors, and machinery. Constant exposure to dust can result in frequent and unscheduled shutdowns and increasing clean-up costs.
When dust escapes beyond site boundaries, it can have a negative impact on near-by properties and eco-systems.
By having proper dust control measures onsite, you can improve operations with continuous productivity, a safer, healthier, and cleaner workplace for employees and meet OH&S and environmental obligations.
How does CoolMist Systems Australia manage dust?
CoolMist Systems Australia supplies dust suppression systems for indoor and outdoor applications. Finding the right dust suppression solution for your workplace may be as simple as a fogging system installed at the dust source or you may require a larger system installed to run a number of zones.
Static line misting systems use high pressure (70bar, 1,000 psi) pumps to atomise water into microscopic droplets to limit the dispersion of fine dust particles. A network of strategically placed misting nozzles emit the fine spray of micron-sized water droplets that absorb the dust particles in the air. The increased weight of the dust particles causes them to fall back down to the ground or to the process material and remain there, leaving the air dust-free. Utilising this method of dust suppression can greatly inhibit dust from circulating throughout the entire facility.
Additionally, mist fans fixed to walls or 360 mist fans suspended from the ceiling can be considered as effective dust suppression tools.
Mist cannons - also recognised as fog cannons, dust cannons, fog makers, spray cannons - are used for dust suppression in many work processes in quarry operations, mine sites, demolition and construction sites.
AJet® Mist Cannons propel atomised mist with a high velocity fan over large areas. CoolMist® mist cannons throw fog from 15 to 150 metres, which makes them a powerful and effective solution for dust control. Water flow rates can be adjusted to regulate the volume of water discharged from the mist cannon to control both surface dust and airborne dust without saturation problems. The cannons can be setup in a fixed or mobile position depending on your specific needs.
A professionally designed and installed dust suppression misting system can remove dust particles from 0.1 to 1000 microns reducing PM10 dust levels and assist compliance with EPA dust control standards. Our team will assess the site and dust intensity, matching water droplet size to corresponding dust particle size. Based on your requirements we will tailor a dust control system designed to work effectively and efficiently.
Why is water droplet size a key factor for effective dust suppression?
To maximise the potential of dust capture by water dust suppression systems, the water droplets need to be similar in size to that of the dust particles. Water droplets that are too large deflect the dust particle away leaving the dust air borne. The mist density (fog cloud) also needs to be greater than the concentrations of dust in the air so that all the dust can be captured.
Our misting systems and mist cannons operate on the principle of binding dust using tiny water droplets similar in size to the dust particles. CoolMist® misting systems and mist cannons effectively break down PM10 and smaller suspended dust particles by using water droplets similar in size to the dust particles.
Tiny, atomised water droplets, 10 microns, form a dense fog and trap the dust particles increasing their weight which causes them to fall from the air. Particles from 0.1 to 1000 microns have little chance to escape and are quickly arrested, removing dust from the air.
The low volume of water emitted from our systems avoids residual problems such as pooling or oversaturation and achieves dust suppression with maximum efficiency at sustainable water usage rates.
