DustBoss dust suppression for low-turbulence applications and fine particle control
First publishedon www.AggBusiness.com
The DustBoss DB-M from Dust Control Technology is designed for applications in which a fan-driven mist could generate undesirable turbulence, including slag or ash handling. The powerful misting head is supplied standard with 9 atomizing nozzles on a 15-foot boom, but the design can be customized for specific dust types, particle behaviors or operating environments.
A global leader in dust suppression technology has 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 from Dust Control Technology is said to be well suited to operating conditions involving very fine dust particles, including slag dust or fly ash.
The unit generates an umbrella-shaped cloud of atomised droplets averaging 50-200 microns in size, projecting the mist about 9.14m under calm conditions.
The powerful misting head is supplied standard with 9 atomizing nozzles and mounted on a 4.57m boom, but the design was engineered for its ability to be customised for specific dust types, particle behaviours 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 types of environments, Peterson says the DB-M is a practical and extremely versatile solution.
“We engineered this unit with the flexibility to accommodate a wide range of conditions. We can adjust droplet size to match specific particle sizes or characteristics, and it can be fabricated on a boom anywhere from 1.2-4.57m in length. It comes with a durable skid mount for easy portability, and the movable head allows users to fine-tune the mist direction.”
The new design features selectable flow settings and the company’s proprietary variable particle sizing (VPS) technology to improve capture efficiency. Nozzles can be added, removed or re-sized as the application dictates.
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.
The DustBoss DB-M 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 30.48m 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 odour control additives, surfactants to improve binding to dust particles or tackifying agents to help seal ground-level dust and prevent it from becoming airborne.
