In mechanical preparation, shredding and mixing creates a starting mixture that is ideal for the rotting processes. If necessary, contraries can be sorted out by screening.
The decomposition and conversion – the rotting process – performed by microorganisms are controlled from the outside through ventilation, mixing and irrigation. We use open solutions like windrow composting, as well as closed processes in rotting tunnels, or combinations of both.
Post processing starts with screening of the cured compost to the desired particle size. Further separation steps may be necessary, depending on the degree of contamination. Following removal of contaminants by sifting, the screen overflow can be reused as structural material or biomass fuel.
Low-speed machines like the Crambo or high-speed ones like the 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.
Drum screens, Multistar star screens and Flowerdisc disc separators separate 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.
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 ventilation and outlet air treatment.
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.
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.
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.
