If containing dust on bulk out-loading is an issue then this award winning Dust Suppression Loading Hopper could be the answer.

The DSH hopper has tackled dust issues on sites handling products such as fertilisers, grain, pet food, sugar, salt, sand and gravel, with throughputs of up to 800 tonnes per hour.

At the point of loading the hopper concentrates the discharge of dry goods into a solid column through free air into any target, including trucks, rail cars, stock piles, storage containers or bags.

Uncomplicated to install and easy to operate and maintain, the hopper reduces hazards, health risks, dust, wastage, cleaning and maintenance costs.

The hoppers are manufactured in Polyethylene, Carbon steel, 304 and 316 stainless and provide a cost-saving and effective solution for the transferral of many dry granular goods.

Contact the Sales Team at Guttridge Limited for advice on how the DSH Hopper can work for you.

Sydney based road tanker manufacturer and rental business, Water Trucks Direct, have made a decision to standardise on Aussie Quik Prime pumps from Australian Pump Industries ’ product range. The company, operating from a facility at McGraths Hill in Sydney make a complete range of water tankers equipped for both dust suppression and water transport.

“We chose the Aussie pumps high pressure pumps because of their big flow, high pressure performance and overall reliability” said Water Trucks Direct Managing Director, Brenden Bastian. “The 5 year warranty offered by Australian Pump is a tremendous bonus” he said.

Water Trucks use both high volume transfer pumps for fast filling in 3”, 4” and 5” sizes. The big volume pumps are either PTO or hydraulic drive with diesel options being available. Smaller tankers in the 10,000 litre range use Aussie 3” self priming gushers that produce flows of up to 1,500 litres per minute. Genuine Japanese Honda petrol engines, one of the major features offered by Australian Pump and Yanmar diesel drives are both used depending on the application and customer’s requirements.

The anticipated $100 million it will cost each year to reduce coal dust on shipments of Wyoming coal out of the Powder River Basin is causing friction between the Burlington Northern Santa Fe Corp. and some public utilities.

BNSF, as well as the Union Pacific Railroad, have spent hundreds of millions of dollars already to reduce coal dust since a 2005 derailment was blamed on coal dust accumulation on the tracks.

But industry officials say additional coal dust suppression measures may be required, costing millions more.

Possible solutions include covering cars, applying a latex coating, or filling cars with less coal.

American Public Power Association estimates whatever method is chosen will add $100 million annually to the cost of shipping coal out of the Powder River Basin.

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.

Received for publication January 31, 2009. Magnesium chloride (MgCl2)-based dust suppression products are commonly used throughout western United States on nonpaved roads for dust suppression  and road stabilization by federal, state, and county transportation agencies.

The environmental implications of annually applying these products throughout spring and summer months on adjacent stream chemistry are not known. Sixteen streams were monitored biweekly for 1 to 2 yr in two Colorado counties for a suite of water quality variables up and downstream of nonpaved roads treated with MgCl2–based dust suppression products.

Eight of 16 streams had significantly higher downstream than upstream concentrations of chloride or magnesium over the entire monitoring period (p  0.05). Mean downstream chloride concentrations ranged from 0.17 to 36.2 mg/L and magnesium concentrations ranged from 1.06 to 12.8 mg/L. Several other ions and compounds, including those commonly found in dust suppression products such as sodium, calcium, and sulfate, were also significantly higher downstream at some sites.

Downstream electrical conductivity (EC), chloride and magnesium concentrations were positively correlated with road surface area draining water toward the stream and yearly amount of MgCl2 applied (R2 = 0.75, 0.51 and 0.49, respectively), indicating that road managers can limit the amount of product entering roadside streams by assessing drainage characteristics and application rates in best management practices. Although MgCl2–based dust suppressants did move into some roadside streams, the concentrations detected were below those reported to adversely affect fresh water aquatic organisms, but the ultimate fate of these ions in Colorado waterbodies are not known.

Soils Control International has accomplished the same results with their product, Top-Seal Dust Control 

DuPont Australia’s groundbreaking work to reduce dust emissions from trains carrying coal and to improve air quality recently earned two industry awards:

* The Australian Mining Prospect Award for Excellence in Environmental Management
* The Australian Bulk Handling Award for Dust Control Technology

Here is the problem. When you use a dust suppression product like Top-Seal Dust Control, You cause the soil to become less permeable. Thus Causing the water in the lake to stay in the lake. Eventually you will Flood your Solar Farm and then it will just be a nice place to dive.

In Los Angeles, California, the city’s Department of Water and Power (DWP) is eyeing flat, dusty, arid Owens Lake as the potential site for a future mega-solar farm, but the initiative is focused less on clean, renewable solar energy than on preventing the interminable dust storms generated by the dry lake bed.

Owens Lake started to run dry when, in 1913, the city began diverting water from the Owens River. By 1926, the former lake was a shallow hardpan. Today, it ranks as the largest single source of PM10 dust (windborn dust particles smaller than 10 microns) in the United States. In fact, one estimate suggests the lake produces up to 8 million metric tons per year.

The DWP thinks that covering 616 acres of the lake bed with solar panels could cut down on dust storms, which threaten the health of nearby Keeler and Ridgecrest residents by delivering up to 23 times the amount of airborne particulate matter federal levels suggest as safe.

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.
