ABSTRACT:
The disclosure relates to an apparatus (1) and a method for compacting material, in which the apparatus comprises a path (10), an infeed device (40) which discharges in an opening (11) disposed in the path, and a spiral (30) which is rotary about its longitudinal axis and has no mechanical shaft. In connection with the discharge opening (12) of the apparatus, baffles (13) are provided which impede displacement of the material, Between the free end (39) of the spiral and the discharge opening (12) of the apparatus, the casing forms a compaction cell (15). The spiral is disposed to at least intermittantly abut against the path, in addition to which the spiral and the path form, in the region of the opening (11), a feed compartment (35) for supplied material, this compartment directly merging into the compaction cell (15).
