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.

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.

Sandvik’s HX410 electrostatic dust suppression system can tackle the challenge of transmit point dust suppression at German company RWE Power AG. The customer can evaluate the HX410 on a conveyor for lignite and overburden in the Garzweiler open pit mine. The conveyor has a capacity up to thirty seven five hundred t/h at a belt speed of seven,five m/s (twenty five ft/s) and a belt width of 2800 mm (one hundred ten in).

Till now, RWE Power AG has used primarily water-sprinkling to cut back the dust to acceptable levels. At a transfer point, RWE Power AG cannot use water-sprinkling because of the coal-on-line-analytic-system which is installed in this place. One double HX410 can be put in on the upstream conveyor and a second double HX410 on the downstream conveyor. Because the Sandvik HX410 has already proven its effectiveness and reliability in more than two hundred applications, RWE Power AG decided to offer it a chance to prove its abilities in the foremost demanding environment.

The system is ionization-based and has been designed to bind dust where it's formed. It is a simple system with terribly low operating and maintenance costs, offering several benefits in comparison to conventional “suction-through-filter” or water-based systems. It is suitable for retrofits or installations on new conveyor systems. The HX410 ensures that chutes, loading points and transfer point don’t generate unacceptable dust emissions. Without proper dust control, each transfer point might generate additional air-borne dust that eventually spreads all over the conveyor area. In most applications, a single HX410 is put in right after the chute on top of the belt.

Essentially there are two totally different normal sizes out there: one, for belt widths 400 to 650 mm (sixteen to twenty five in); and 2, for belt widths 800 to 1400 mm (31 to 55 in). For wider belts, custom created constructions can be offered by Sandvik. The power requirement for a normal system is below five hundred W and maintenance time is less than one hour per month. The system picks up particles in the range of 0.01 to 100 µm. The potency for an average particle size of five µm is usually higher than 90%.
Applications and use of the HX410 can be found at bulk material transfer points in industries like: mining, aggregates, steel, cement, foundries, glass and paper. But, it's not suitable for environments with explosive dust.

As scores of cities are trying to survive the central bank induced fiscal calamity, services for those communities are on the chopping block.  Often times we presuppose the services which our monies deliver, and whether or not you know it, all those revenue taxes that you pay are never going to these services. Those taxes go off to the secret banks that hold the Federal Reserve central bank. The taxes which are used to sustain our state, county or township, are derivative from taxes that we pay whilst going about our daily lives.

An illustration would be the gas tax supplementary to each gallon of gas we buy. That money is employed to keep the roads. When citizens travel less, the proceeds from gas taxes start to fall off significantly. At some moment we start to have diminishing returns. Such is the situation when the powers that be choose that Dust Suppression on our roads will have to be cut. Defective roads less travel – less travel less gas tax

When we take a buck from a citizen that's constructive and use it on a non practical incident, that buck is finished forever. If we utilize that dollar for a industrious event the dollar stays in the system to deliver more taxes into the system again.

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.
