Powder Recovery System


In a Spray Drying System, the dryer exhaust air will contain a small amount of powder when it exits the drying chamber. This powder is referred to as fine particles or fines. It is necessary to separate these particles from the exhaust air and recover the particles not only for economical reasons but to prevent air pollution by excessive powder emission to the atmosphere.


Powder Recovery Systems include :

  • Cyclone
  • Baghouse
  • Wet Scrubber
