Rotary kiln

Rotary kilns are used for a wide range of thermal material conversion processes for free-flowing, granular bulk materials. The bulk material can be calcined (lime), sintered (cement), roasted (phosphate), expanded (expanded clay), regenerated (lime slurry) or changed in its crystal structure (aluminum oxide) in the rotary kiln.
The bulk material is fed in counterflow to the hot gas. The rotating rings support the weight of the rotary kiln via the rollers and the foundations and are supported two or more times. The rotation of the rotary kiln takes place via a drive (e.g. sprocket and pinion drive, friction wheel drive).

ZETTL GmbH has many years of experience in special plant construction and can manufacture rotary kilns in any size and according to customer requirements. Pyrolysis furnaces have proven themselves for the recycling of used tires, waste wood, composite materials, biomass and sewage sludge. The advantage is obvious, as the rotary kilns can carry out various operations for thermal processes individually or in combination, for example for high throughputs and process-related, long dwell times.
