CW Machine WORX, the manufacturing division of Company Wrench, has introduced a new dust suppression system in the shape of the Dust Destroyer. Built around a 60 kW (80 hp) diesel engine, the Dust Destroyer provides a coverage area of 2,500 m2 (27,000 ft2) to a maximum height of 23 m (75 ft) with 60 degree oscillation. Optional features include a booster pump and chemical odour control.

The dust from a mine is significantly different from the dust you find in your home. Dust in your home primarily consists of dead skin while mine dust is almost exclusively a mineral in a fine powder form.

Most written definitions of mine dust include the following: dust from drilling, blasting, smashing or handling of rock. The majority of the dust created by one of these activities are too large to stay in the air for an extended period of time and account for about 40 percent of all dust created at a mine site. The remainder is less than 10 micrometers in size. The majority of these particles is less than 2.5 micrometers and come from the exhaust of equipment used on the mining site.

The smallest size particle is what is most hazardous to the population’s health. The larger dust particles are an eye sore and are cost a lot to clean up, but are less hazardous to one’s health.

The smaller particles do make certain health hazards that include respiratory problems due to the fact that they are in the air that is breathed in to the lungs. This can be minimized if mining personnel were to wear masks designed to filter out the dust.

Hinowa has introduced a crawler mounted dust suppression system through the marriage of its Goldlift 14.70 tracked carrier to a WPL410 rotating water spray system. The Goldlift 14.70 is able to elevate the nozzle to a maximum height of 12 m (39.4 ft) to maximise the throw area. The WLP410 itself has a maximum throw distance of 30 m (98.5 ft), offers 320º rotation and can cover up to 2,800 square metres (30,100 square feet). Recommended operating pressure is 10 Bar, at which pressure it uses 35 litres (7.7 gallons) of water per minute. Hinowa has also made this unit available on its TP1800 tracked forklift.

Techniques for removing dust from the air have varied over the years. During that time, methods have focused on a dust collection and suppression system. The difference between a dust collector and a dust suppression system is how the dust is initially treated. Dust collectors form a vacuum to capture the dust and remove it from the surrounding air. It is then transferred to a filter or bag for proper disposal. A dust suppression system does not attempt to remove the dust from the physical area. Instead it places it back to its source. Best of all, a dust suppression system is more affordable.
