The rugged durability of Nelson Big Gun® Sprinklers makes them a favorite for mining dust suppression. Big Guns are preferred because of the ability to move a large amount of water in a short time. The large nozzle is less likely to plug and the filtration requirements are minimal. All bearings on the gun are sealed ball bearings. Some sprinklers are mounted on high towers in order to throw over the piles. Alternatively, a high trajectory Big Gun sprinkler (fixed 43° and adjustable 15°-45° models available) can achieve the necessary stream height to reduce tower height and clear the top of the piles. A clear winner in the fight to control fugitive dust issues for tailing dams, heavy haul roads, stockpiles, aggregate terminal, erosion control and air quality.

SPECIAL OPTIONS INCLUDE:
• ANODIZED, POWDER COATED, and STAINLESS STEEL BIG GUNS for sprinkling with corrosive waters.
• COUNTERBALANCE KIT for operation of the Big Gun with a tilted riser.
• WEDGE INSERT for modified trajectory.
• HEAVY-DUTY BRONZE BRAKE for operation in environments with airborne, abrasive, dust particles (100 Series only).
Using Big Guns and 800 Series Control Valves in conjunction with Nelson's Control System allows mining operations to automate irrigation for scheduled fugitive dust suppression.
