ABSTRACT:
Already ripened compost is subjected to a sifting process directly following a drum sieve. The duct conveying the flowing air is connected to the outside of the drum sieve and is thus fed with the material falling through the sieve. The duct is constructed as a sifter which separates a light fraction from a heavy fraction. At least one lock is arranged in the path along which the heavy fraction moves.
