We reused an existing 18,000 cfm dust collector for the rotary kiln dryer. This provided a challenge since the collector was over 90 ft away from the dryer. A 30" dia grasshopper duct was designed originating from the dryer discharge up to the top of the 65 ft mill structure and back down to the dust collector in the existing process area.
Dryers used to efficiently process large quantities of bulk materials that need reduced moisture levels. The most common are fluidized bed dryers, rotary dryers, rolling bed dryers, pharmaceutical dryers, suspension/paste dryers and dispersion dryers.
