ABSTRACT:
Apparatus for conveying and compacting material which includes fractions of different sizes, densities, elasticity, moisture-content, etc., wherein a shaftless spiral is disposed in a casing and the spiral is driven in rotation at an end of the casing where the material is fed into the casing. At the opposite end of the casing, i.e. a discharge end, the casing surrounds the spiral with slight play, and, moreover, the casing extends beyond the spiral to form a compaction zone. Counterpressure brakes the movement of the material to compact the material in the compaction zone. The casing is provided with drainage holes for discharge of liquid expressed from the material during passage through the casing. At the discharge end of the casing, the compacted material is cut into particles, preferably by a second spiral in a second casing which also serves to convey the cut material away from the casing.
