DUST CONTROL TECHNOLOGY recently introduced a new low-turbulence design for applications in which a fan-driven mist would be undesirable. Developed in response to extensive customer input, the DustBoss® DB-M is suitable for operating conditions involving very fine dust particles, including slag dust or fly ash. The unit generates an umbrella-shaped cloud of atomized droplets averaging 50-200 microns in size, projecting the mist about 30 feet (9.14 meters) under calm conditions.
The misting head is supplied standard with nine atomizing nozzles and mounted on a 15-foot boom, but the design was engineered for its ability to be customized for specific dust types, particle behaviors or operating environments. “There are a number of applications where a fan-driven dust suppressor would introduce too much air movement,” explained Dust Control Technology CEO Edwin Peterson. “In some cases, that could actually cause ground-level dust to become airborne.”
For those environments, Peterson said, the DB-M is a practical and extremely versatile solution. “We engineered this unit with the flexibility to accommodate a wide range of conditions,” he continued. “We can adjust droplet size to match specific particle sizes or characteristics, and it can be fabricated on a boom anywhere from 4-15 feet in length. It comes with a durable skid mount for easy portability, and the movable head allows users to fine-tune the mist direction,” he added.
The new design has selectable flow settings and proprietary Variable Particle Sizing (VPS) Technology to improve capture efficiency. Nozzles can be added, removed, or re-sized as the application dictates.
Just 10 PSI of water pressure is required from the supply hose when using the integrated booster pump, giving the DB-M an output as high as 24 GPM at 200 PSI. An in-line 30 mesh filter stops any solids 600 microns and larger, and the manufacturer recommends that it be used at all times. If using potable water, nozzles can be inspected just once a year.
Configured for U.S. markets for 3-phase / 480 volt / 60 hertz power, the full current load is approximately 12 amps. It can be configured to match power supplies in virtually an region in the world. The recommended minimum generator set is 25 KW. Supplied “bare wired” with a 100-foot (30.48 meter) 10/4 electrical cord, it can be ordered with any plug for a modest extra cost.
The DB-M can also be supplied with an optional dosing pump for precise metering of odor control additives, surfactants to improve binding to dust particles, or tackifying agents to help seal ground-level dust and prevent it from becoming airborne.
