PROCESSES INVOLVING GRAIN DUST

Most grain dust is created by material handling processes, which include:

Dump pits

Break milling Sifters / Sorters / Classifiers

Elevator legs

Bin / Silo loading Roller milling

Conveyors

Packaging Barge / Rail car / Truck loading

Garner scales

Drying Mixing bin venting

Grain cleaners  

Hammer milling  

 

 

 

SPECIAL CONSIDERATIONS FOR GRAIN DUST

  • When grain reaches an export terminal it has been handled between 5 and 10 times. As a result, dust loading may be higher andhtis should be taken into consideraiton when sizing collectors.
  • Cartridge style collectors are typically suitable for seed production plants because seeds are handled more gently than common grain and therefore, emit less dust.
  • Oilseed processing often involves both heat and oils so be sure to consider both when selecting dust collectors.

HEALTH AND SAFETY CONSIDERATIONS

Grain dust can be highly combustible so an understanding of NFPA, OHS, and EPA regulations is often required. Typically any collector may require an explosion mitigation strategy such as explosion vents or chemical suppression systems.
