WheEisenmann rotary kilns are ideal for waste heat recovery from solids and/or sludge. Depending on the input material, you can deploy brick-lined or all-steel rotary kilns. The input material also determines whether the kiln is operated in co-current or counter-current mode. Eisenmann designs and supplies peripheral components, such as input material storage and preparation, feeding systems, waste heat recovery and made-to-measure flue gas purification systems, customized to suit your requirements and in line with your input material.
