Abstract

A waste conveyor includes a conveyor channel. A feed shaft is connected to the conveyor channel. A worm is disposed in the longitudinal direction of the conveyor channel. The worm has a shaft with an axis. A first metal cutter is disposed at an edge of a portion of the worm and is curved relative to the axis of the shaft. A second metal cutter is disposed at a portion of the conveyor channel, is curved relative to the axis of the shaft and has a radius of curvature being greater than the radius of curvature of the first metal cutter. The two metal cutters are disposed side by side and approximately concentric to the shaft, at a predetermined rotary position of the worm.
