Abstract
A classifying and sorting machine for refuse particles, particularly household refuse and other refuse having a composition resembling household refuse, has a rotatable screen drum the diameter of which is within the range of 1:1-1:2 relative to its axial length. Baffles of sawtooth-shaped configuration are arranged in the drum rotating with the same and having inwardly directed ripping teeth. Annular baffles in the drum subdivide the drum into two or more axially adjacent compartments and each have an inner diameter smaller than the inner diameter of the drum, and an arrangement is provided for rotating the drum at an angular velocity which is smaller by between about 20-50% than the velocity at which the drum contents are pressed by centrifugal force against the circumferential drum wall.
Claims12
A sorting machine, particularly for refuse particles comprising a rotatable screen drum having a diameter within the range of about 1:1 to 1:2 relative to its axial length;
- a plurality of axially spaced annular sets of strip shaped baffles arranged in and rotatable with said drum, and having inwardly directed ripping portions;
- a plurality of axially spaced annular baffles in said drum and each having an inner diameter smaller than the inner diameter of the drum;
- means for rotating said drum at an angular velocity which is smaller by between about 20-50% than the velocity at which the drum contents are pressed by centrifugal force against the circumferential drum wall;
- and at least one turnable processing shaft extending through said drum parallel to and laterally offset from the axis of rotation of said drum.
