 "One-stage sorting into two fractions - low alternative")
One-stage sorting into two fractions - low alternative
The undersize fraction is transported by a belt conveyor directly to the truck loading bed or to a large-capacity container. The oversize fraction remains on the spot. Example of use sorting of compost before dispatching.
 "One-stage sorting into two fractions - high alternative")
One-stage sorting into two fractions - high alternative
The undersize fraction falls into the hopper from where it is handled by means of a front loader. The oversize fraction falls into another concrete hopper. Example of use preparation of fuel for a boiler burning wood waste, classification of gravel.
 "One-stage sorting into two fractions with shredding of the oversize fraction")
One-stage sorting into two fractions with shredding of the oversize fraction
The undersize fraction is transported by conveyors upwards to a free stockpile, truck or into a container. The oversize fraction continues into a double-rotor shredder where it is shredded to the required size. Example of use compost processing. It is the ideal solution for small and large-capacity composting plants.
 "Three-stage sorting into four fractions - multi-level alternative")
Three-stage sorting into four fractions - multi-level alternative
By means of three roll screens the supplied material can be efficiently sorted into four fractions in a relatively small area. Example of use sorting of gravel, construction debris, preparation of fuel for boilers burning wood waste.
