Haul Road Dust Suppression Sprinklers
Fixed rain-gun sprinkler lines along haul roads keep the surface damp and reduce dependence on water tankers.

The Haul Road Dust Control Spray System is an automated, periodic watering system designed for mining operations to prevent dust lift-off when haul trucks pass through the area. This solution eliminates the high costs associated with water tankers and reduces the need for manual labor and equipment.
Haul and access roads are critical components of mining operations and are used by mobile equipment to transport materials to and from mining areas. However, the road network in a surface mine site is extensive and can generate a significant amount of dust, which can cause harm to both equipment operators and workers in the vicinity. The main source of dust is caused by the forces of the wheels on the road surface and the turbulence created by the vehicles. The majority of the dust particles from haul truck emissions are larger than 10 μm in diameter.
To effectively control and suppress haul road dust, a comprehensive strategy should be developed during the road construction phase and implemented throughout mining and transportation operations. Synergy Spray Systems can assist mine operators with the installation, commissioning, and maintenance of haul road dust control and suppression systems. This can involve a combination of technologies, such as truck sprinklers, permanent tube systems with rotating sprinklers, and automated spray systems.

Dust Suppression Applications
Synergy Spray systems is an growing dust suppression integrator helps overcome the challenge of creating safer roads and workplaces for people, industry and communities.
Our products also assist in making surfaces within mining, construction, infrastructure and farming projects stronger, longer lasting, as well as more cost-effective and environmentally responsible.

Dust Control Products
Specially formulated polymer-based dust control solutions not only prevent the generation of dust but also stabilize the treated surface.
They can be deployed quickly and easily, without any negative impacts on the environment and solve the problem of dust impacting on fruit, cropping, and feed viability in the horticultural and agricultural sectors.
What we need to design your dust control
Send these details and we can propose a system layout, nozzle count and water/power requirement.

ExploreQuestions about haul road sprinklers
Which dust suppression system is right for my plant?
It depends on the dust source and how much moisture your material can accept. Dry fog suits enclosed transfer points with little added moisture; plain-water sprays suit open conveyors and stockpiles; fog cannons cover open areas. We recommend after reviewing the site details.
Does the water need to be treated?
Fine fog nozzles have small orifices, so filtration is always needed and softened water is often recommended. Plain-water spray systems tolerate coarser filtration.
Can the system run automatically with the conveyor?
Yes. Systems are normally interlocked with the conveyor, crusher or tippler so they spray only when material is moving.
Do you visit the site?
Yes, a site survey can be arranged so the nozzle positions, pumps and controls are designed for the actual layout.
