How does a dust cannon differ from hosing the area with water?

A cannon breaks the water into a fine mist and throws it into the air, so it binds dust already hanging over the site. Hosing wets the ground and limits dust rising from the surface, but it does little for dust already in the air — large droplets catch it poorly.

Mobile or stationary?

A mobile unit suits situations where the source of dust moves — demolition or earthworks. A stationary one makes sense at fixed points such as a crusher, a screener or a transfer station. Access to power and water also decides the choice.

Does a dust cannon work in wind?

Yes, but the wind decides where the mist goes. The cannon is positioned so the wind carries the mist over the dust source; in strong wind it becomes less effective.

Is one cannon enough for a whole site?

That depends on the size of the site and the number of dust sources. With one fixed source it often is; on a large site with several work fronts you usually need several units or a stationary system.

Dust suppression cannons — water-mist dust control

Dust suppression cannons

We work with water-mist dust suppression — wherever airborne dust has to be brought down on a construction site, during demolition, on stockyards or when handling aggregates.

A dust cannon produces a cloud of fine water mist that binds airborne dust particles and drops them to the ground. Unlike hosing the area down, it works in the air rather than just on the surface — it catches dust that has already risen.

Typical uses are demolition and tear-downs, crushers and screeners, aggregate stockyards, handling of bulk materials, and haul roads on site. Increasingly this is not only a matter of working comfort but also of the client's requirements and of neighbouring housing — and Polish health and safety rules for construction work require waste to be removed in a way that limits its scatter and dust (Regulation of the Minister of Infrastructure of 6 February 2003, § 39).

The choice of unit depends above all on the range that has to be covered and on the power supply and water source available. Describe your situation and we will propose a mobile or a stationary solution.

How it works

How a dust cannon works

A dust cannon is a fan with a ring of nozzles at the outlet. The nozzles break the water into fine droplets, and the airflow from the fan carries the mist far across the site. The droplets collide with dust particles in the air, bind to them and fall out together.

How well it works depends on droplet size: airborne dust is captured best by droplets of a similar size to its particles. Large droplets are good for wetting material on the ground but catch airborne dust poorly — which is why cannons work with mist rather than a jet of water.

Selection

What the choice of cannon depends on

Reach and area

How far the mist has to reach and how large an area it must cover. Manufacturers quote throws from about 30 to over 100 metres, with the densest mist landing short of that limit. On a big site one unit may not be enough.

Power supply

The fan and the pump need electricity — from the site supply or a generator.

Water source

A connection or a tank with enough capacity to cover the water use for the whole shift.

Mobility

A mobile cannon follows the work front; a stationary one serves a fixed point — a crusher, a screen, a loading point.

Wind and positioning

Wind carries the mist, so the cannon is placed for the cloud to land over the dust source. Rotation and tilt adjustment let it cover a larger area.
