ABSTRACT:
A pneumatic compressor for the compression of waste comprising a cylinder (1) with a piston (2), which via a piston rod (4) activates a compression plate (3), which is slidably mounted in a compression chamber (5) which has a top door (6) through which waste paper is thrown into the compressor, and a bottom door (7) through which a finished bale can be taken out, which compression takes place in a series of compression cycles, which each time is charged with a new portion of waste, until the waste offers a counter pressure corresponding to the pressure which the piston (2) can exert at a pressure of 8 bars. In 80-90% of the compression cycles necessary for the compression of a bale, the piston (2) reaches its bottom position in the cylinder, and each time the pressure reaches a pressure of 8 bars in the cylinder (1).
