Dusting Off the ... DUST !

Pressure Control Cabinet
In July of 2010 , I had mentioned in the newsletter about completing a fabricated in-house mister system to reduce airborne dust inside the crusher building . There was a steep learning curve on how to make it work effectively and we thought it turned out pretty well . As we evaluated the system there were still some areas where we could make improvements . In an effort to make it better we learned to control dust ; the water particles could not be any larger than the dust particles so a true fogger system was needed .
“ There was a steep learning curve on how to make it work effectively and we thought it turned out pretty well .”
The Fog method of dust control has been used for many years and is one of the most effective methods to suppress fugitive dust in materials handling operations . Water droplets are produced by using compressed air to force water through a special nozzle which produces droplets less than 100 microns in size . The dust particle passes through the fog ; the fog then captures the particles and drops them back to the source ( conveyor or cone ). Our system consists of 64 hydro-pneumatic nozzle assemblies , connected by piping to solenoid and pressure control cabinet ( s ), which supply regulated and filtered water and compressed air . An electrical cabinet is required to control on / off operation of the system ; this required us to construct a new building to house an additional air compressor . However , all the hard work has paid off ! We now have an effective way to control dust .
Now if only I could keep my house dusted !
