KAVERI – Dry Fog System controls virtually all types of breathable and fugitive dust ranging from 1 to 800 microns in size. The system utilizes a dual fluid, water and air nozzle that produces an ultra fine droplet size fog that achieves dust suppression through agglomeration. No chemical is required in this system and water.
Fog is produced using sonic type air assist nozzles, the only nozzles capable of producing water droplets in the 0 to 30 micron size range at practical pressures and flows. . Fog based dust control technology was first used in coal mining applications in 1995 in the Powder River Basin region of the western United States.

The results show that with the gas liquid ratio (GLR) increasing, the spray state of an arc jet nozzle presents successively water jet, foam jet and mist. Under a reasonable . Wang et al. designed a full cone nozzle and applied it to control dust at a heading face in the Xuehu Coal Mine in China . The flat jet nozzle is widely.

These high performance dust suppression nozzles are intended largely for use with conveyors in the mining industry. Spiral spray patterns . The movement of conveying crushed stone, coal, or sand, stirs up and creates a dust cloud, which can be suppressed by spraying water as a fine mist or fog. Adding finely sprayed.
Dust Control in Mining - controlling dust is a common application in which BETE nozzles are used. Dust control can take many forms. The two main categories are preventative and symptomatic.
Academic Research. Research literature has long recognized that small droplet size is the key to dust suppression system. The following explanation comes from work at the Colorado School of Mines: When water droplets that are sprayed to control coal dust are too large, the dust particles flow around the droplets, and thus.
Jul 1, 2010 . Public testimony given to the EPA on fogging systems has confirmed that 29-year-old prediction: Dry fog can be the most cost effective dust control system available. The BDT designation was due in part to the supportive testimony by representatives from PRB coal mines, PRB coal-fired plants, mining.
With appropriate nozzle placement, shroud design and baffling dry-fogging can generate a layer of fine water droplets (fog) that a dust particle cannot pass through without colliding with a . We are the leading supplier of dust control equipment for the mines in the Powder River Basin and for the utilities using PRB coal.
One of the greatest problems facing the Coal Mining research engineer at the present .. a test gallery totally quenches the flame at this barrier; water barriers to create this high speed mist are under investigation for use in European mines (18), (19). Operation of . easily operate a 20,000 psi jet nozzle by hand (nozzle dia.
A fog nozzle is a firefighting hose spray nozzle that breaks its stream into small droplets. By doing so, its stream achieves a greater surface area, and thus a greater rate of heat absorption, which, when compared to that of a smoothbore nozzle, speeds its transformation into the steam that smothers the fire by displacing its.

The Importance of Nozzle Selection in Dust Suppression Systems. Regardless of the type of material you are producing (eg coal, ore, etc.) and the physical location of the operation generating the dust (ie. underground or above ground mining) the quickest, easiest and most effective way to control errant dust is with a dust.
Extracting valuable minerals and metals from the earth's soil has been done for centuries. Mined materials such as sands and gravels, line, coal, gold, silver, copper and aluminum are used in making roads and buildings, making concrete and making electric circuits. Mining, in some regions, provides the foundation.
