ABSTRACT:
An apparatus for the compaction and reduction of liquid content in a material includes at least one floating helix (3) rotatable about its axis by drive means (4, 30) and disposed in a casing (2) which, at least along a portion of its extent in the longitudinal direction, completely encloses the helix. In conjunction with the discharge portion of the apparatus, the casing encloses the helix with slight play. Seen in the direction of movement of the material, the discharge portion includes a helix-free region most proximal the discharge opening of the casing, intended for the formation of a counterpressure member which arrests the movement of the material. In this region, the helix is provided with an extension body (100) which reduces the available conveyor surface area. As a rule, the body is a cylindrical hollow body which as a rule is provided with drainage apertures.
