Rotary Kiln Shell Design Technology. In the cement business, widely using iron cylinder equipment to do chemical, mechanical or physical disposal of solid materials is called a rotary kiln. The rotary kiln's inner side usually …

Rotary dryers are used prolifically throughout industrial processing operations to dry bulk solids, helping to prevent downstream equipment from clogging, creating a more flowable feedstock, and producing a finished product ready for market.. Achieving optimal performance of a rotary dryer is the result of finding the right balance between the …

TYPE 1: Counter current rotary kiln; TYPE 2: Co-current rotary kiln; Type 1: Counter current rotary kiln. Flue gases flow in the opposite direction of the waste, against the inclination of the kiln. Solids move by the rotary motion and by gravity from the high end to the low end of the kiln. Photo: A counter-current rotary kiln example. Photo ...

Most rotary kiln incinerators were of the co-current design, which provides for more rapid ignition of the waste feed and greater gas residence time for combustion than does the counter-current design. Hazardous or nonhazardous wastes are fed directly into the rotary kiln, either continuously or semi-continuously.

 — According to the different flow directions of gas and solid in the rotary kiln, the rotary kiln can be divided into two types: co-current flow kiln and counter-current flow kiln.

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.
