Composting plants
Our products and services range from mobile machines for open composting systems, to large plants with stationary machines for preparing and packaging the final product.Â
Gentle
shredding
Low-speed machines like the Crambo or high-speed ones like Axtor are used for shredding. Both types can be adjusted to output the desired particle size, using the appropriate screen baskets and teeth. This step can be enclosed or open-air, depending on the input material and local conditions.
Cleaning
and mixing
Drum screens, Multistar star screens and Flowerdisc disc separators seperate off contraries and noncompostable fractions. At windrow composting the material is mixed with structure material and screen oversize during the layered build-up with a wheel loader and homogenized in subsequent mixing with a turner.
Open or
closed
The input material and the associated limiting factors also decide for the rotting process whether it is conducted closed, i.e. in an indoor part of the system, or open as windrow composting. The first phase of the process often takes place in a closed system with vendilation and outlet air treatment.
Windrow
composting
Turning compost with a Topturn compost turner improves ventilation, enables re-watering and ensures mixing of the different rotting areas in the windrow. The process is generally complete after 6 to 12 weeks.Â

To attain a product of uniform particle size, and to separate off any contraries still present, the compost is screened. Komptech has a wide range of mobile and stationary drum and star screening machines for this process. The particle size produced is based on the intended use, ranging from coarse compost fractions for agriculture to finely screened material for mixing into garden and potting soil.Â
Reinigung des
Ãœberlaufs
Screening after composting generates a usable fraction and a screen overflow. The overflow can be run through a Hurrikan windsifter to remove the light components and then used as structure fill, or it can be used as biomass fuel once the stones have been removed by a Stonefex.Â
