Rotary Kiln Energy from Waste (EfW) Plants
Temperature Gradient: One of the main challenges in counter-current kiln construction is the temperature gradient across the fire door, sealing off the waste hopper from the kiln entry. BIC Group has developed specially engineered designs and leverages decades of experience to create reliable and long-lasting fire doors, overcoming this obstacle.

Cement Rotary Kiln Design
The length of each part of a rotary kiln is designed based on the inner diameter (D) of the kiln shell.. 1) The length of the kiln head overhanging section (l 1): l 1 = (1.2~1.5) D. As the first section of a rotary kiln, l 1 is better not to be designed too long, or the length of the effective parts of the kiln will have to be shortened.. 2) The length of the preheating section (l 2): l 2 = (5 ...

Rotary Kiln Design: Direct Fired vs. Indirect Fired
Direct-fired rotary kilns rely on direct contact between the process gas and the material in order to heat the material to the specified temperature. Direct-fired kilns can be either of the co-current design, or counter current design, referring to the direction that the process gas flows through the drum in relation to the material.

Rotary Kiln Design: Dams
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.
