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.
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.
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.
