Rotary Kiln Design Dams  Feeco International Inc

Rotary Kiln Design Dams Feeco International Inc

How a Rotary Kiln Dam Works. A dam in a rotary kiln works much like a dam in a river; material builds up behind the dam, forcing retention time and bed depth to increase. Material then spills over the dam, and discharges from the rotary kiln. Since most kilns utilize a counter current air flow, end dams are the most commonly employed type of dam.

Mean Residence Time And Holdup Of Solids In Rotary Kilns

Mean Residence Time And Holdup Of Solids In Rotary Kilns

Aug 01, 2006 For rotary kilns without a discharge dam, an equation was fist given by Sullivan et al. (1927) to calculate the mean residence time of the solids: (1) MRT = 1.77 L D Θ n β. Accordingly, MRT is proportional to Θ and the size ratio L / D , but inversely proportional to the rotation speed n and the kiln inclination β .
