ABSTRACT:
A sieve drum (1) for sieving out waste or the like, in particular domestic refuse, having an intake associated with an open end of the drum is mounted pivotably at an angle or inclination (w) approximately at the middle of its length (n) and is to have perforations (14, 15) of different sizes. It has also been found advantageous for the perforations (14, 15) to be of cross-sections which decrease in a direction of the sieve drum (1) from one end thereof.
