(2) Rotary Kilns – Year 2007!!!

 

Kilns are 2.5 meter ID and 16 meters in length.  Kilns rotate between 0.2-2.0 RPM.  Maximum temperature is 925°C. Each Kiln is equipped with an 8MM Btu burner.

 

The rotary kilns operate in a co-current configuration with the feed and process gases moving in parallel through the kiln from the feed end toward the discharge breeching. Supplemental air is injected through a lance extending into the feed end of the kiln.
