The DB-M dust suppressor.
The DB-M is designed 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 m) under calm conditions. The new design features 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.

Annual Salary Survey
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
