Mining spray nozzles

Spray Nozzle Engineering supplies the largest range of quality spray nozzles and equipment for the Australian and New Zealand mining and quarry industries. The company provides technical support to a wide range of industries from minerals processing, steel, alumina and petrochemical; these services include spray droplet, spray coverage analysis, custom solutions and more. 

As the exclusive supplier of BETE spray nozzles, the industrial nozzle range includes:

BETE not only has one of the largest ranges of nozzles in the world but has an enviable reputation for fire protection, pollution control and flue gas desulphurisation.  Spray Nozzle Engineering is the exclusive distributor of BETE nozzles, Stang water cannons and monitors and a large range of hose reels for different applications.

Dust is a chronic problem at many stone or dirt quarries or mines. We offer dust control products that cater to conveyors, transfer stations, hoppers, crushers and unloaders. Below are common dust suppression nozzles:

Air atomising nozzles

Air atomising nozzles

These nozzles use a secondary fluid or gas to break up the primary spraying fluid into an exceptionally fine spray (atomisation).  The secondary fluid is usually air, but can be any gas, but the term “air atomising” is used for all.

Spiral full cone nozzles

Spiral nozzles

A relatively small average droplet size can be achieved with the TF range of spiral nozzles. But within the mix of droplet sizes there exist some larger drops. These tend to concentrate in concentric rings of higher spray density.

Impingement misting nozzles

Impingement misting nozzles

With this design of nozzle the fluid is ejected from the nozzle orifice and impacts upon a pin in the direct path of the water flow. This breaks up and disrupts the flow into a fine spray cone. As the fluid is being broken up by impact this allows for a larger orifice, thus allowing for more viscous or “dirty” fluids to be sprayed into a fog pattern.

Wash applications rely on the impact of the spray to help dislodge residue. The full cone spray pattern nozzles distribute the kinetic energy of the fluid being sprayed over a large area and this reduces impact.  So in order to achieve the required impact other spray patterns are required. Typically a flat fan spray pattern will be used.  The problem is that this only cleans a thin line, so some kind of relative motion will be needed to clean a target area. This motion can be provided by a conveyor moving product under a cleaning spray bar or by a moving spray bar. Below are common washing nozzles for mining:

Deflector Flat Fan Nozzles for Cleaning

Flat fan spray nozzles

The deflection type nozzle produces the flat fan pattern by deflecting the fluid stream against a curved surface after exit from the nozzle orifice.  The impact of the fluid on the deflection surface causes the desired atomisation and the geometry of the surface shapes the resulting spray into a flat fan pattern.

Elliptical Orifice Flat Fan Nozzles

Flat fan spray nozzles

With this design of nozzle the spray pattern is formed by the exit of the fluid through a shaped orifice.  This spray will be a high impact flat fan. These nozzles have a lower profile than their deflector design cousins and so may be more appropriate where space is confined.

There are stringent safety regulations in place to help mitigate this risk to life and property. It is useful to point out that the term fire protection refers to a system that is designed to protect an asset from the effects of fire as opposed to a fire extinguishing system that will help put our fires or a fire prevention system that helps stop fires from occurring in the first place. BETE produces a range of spiral nozzles (the N series) for fire protection systems. These combine fine droplets with the excellent spray reach and impact needed to work through the often strong thermal currents generated by fire. The combination of small and large droplets from these nozzles means the cooling power of small droplets can be delivered to fire by effectively being carried by the larger droplets. The N series of fire fighting nozzles have been approved by Lloyd’s, FM and UL. Below are common fire protection nozzles for mining:

Spiral nozzles for fire extinguishing systems

Fire protection nozzles

These nozzles produce a relatively fine spray with low medium droplet size. This gives them great cooling power. But the spectrum of droplet sizes is also larger than most nozzles. This makes them ideal for fire protection systems as the heavier droplets act to carry the smaller droplets to areas they would otherwise fail to reach. This is particularly important in fire protection systems as the air currents caused by heat may simply blow very fine droplets away before they can act on the fire.

Misting impingement nozzles for fire extinguishing systems

fire protection nozzles

With this design of nozzle the fluid is ejected from the nozzle orifice and impacts upon a pin in the direct path of the water flow. This breaks up and disrupts the flow into a fine spray. This nozzle can produce the finest spray of any direct pressure nozzle making them suitable for many halon replacement fire extinguishing applications.

Small orifice misting nozzles

Misting spray nozzles

By forcing fluid through very small orifice at high pressure sufficient turbulence is created to atomise the spray into a fine fog. At lower pressures such a nozzle will form a mist. This makes these nozzles ideal for water misting fire extinguishing applications. As these nozzles work by having a very small orifice they are prone to clogging. Effective filtration is thus important. Bete’s MicroWhirl range of small orifice misting nozzles are a suitable choice for many halon replacement/ water misting fire extinguishing systems.
