ROTARY KILNS
the rotary kiln. Directfired rotary kilns can operate in either the cocurrent mode, where combustion gases and solids move in the same direction, or in the counter current mode, where the gases and solids move in opposition to each other. While all FEECO kilns are custom engineered around the material to be processed and the unique processing
