Specialist firefighting equipment supplier Dose-Tech, in January, supplied a mobile remote-controlled water monitor, specifically designed for extended dust suppression, to specialist mine vehicle builder Cobra Petro Products for dust control of mine heaps and road surfaces at a local iron-ore mine.
The mobile dust suppression system comprises an on-site servicing vehicle with a 30 000 ℓ water tank, which pumps water at 2 500 ℓ/min, supplied by Cobra Petro Products, as well as the DoseTech-supplied Akron Severe Duty water monitor, which was retrofitted to the vehicle.
The monitor was developed by international manufacturer Akron Brass at the request of the Australian mining industry in response to the occupational hazard that dust poses to people, the environment and mining machinery.
Dust suppression is, therefore, an important aspect of any mining business, states DoseTech.
“When disturbed, dust creates poor visibility, dangerous working conditions and potentially irreversible respiratory disease. It is imperative that a dust control management system is implemented on mines and in other locations where dust is a problem.
In dry climates especially, the control of dust particles is important. Dust suppression takes care of such risks and the Akron Severe Duty monitor is an effective dust suppression solution,” says DoseTech product manager Corné White.
He adds that water spray systems remain the most efficient and cost-effective means of dust control for both process and fugi-tive dust and vapour emissions.
The Akron monitor works at a maximum pressure of 17 bar with a maximum flow rate of 2 900 ℓ/min on the electric unit and 4 800 ℓ/min on the manual unit.
It is able to function with recirculated or recycled water, resulting in further cost savings.
The Akron monitor can be fitted with various control options and nozzles for mining applications, such as a deluge tip nozzle, creating a direct, solid bore water stream with a 70 m to 90 m throw distance; or a fog or jet nozzle, which allows for water stream dispersion changes.
The stainless steel model has a 320° rotation in remote control mode and a 360° rotation in manual mode and has fully sealed, nonlubricated polymer bearings to protect it from dust and grit. The bearings also require no greasing.
DoseTech MD Mike Feldon says the Akron Brass product quality is in keeping with the high standards expected by users of its products.
“We are pleased to be able to bring this high-quality product range to the South African mining industry, having already established a sound reputation in the fire protection field in the country,” says Feldon.
