摘要

An apparatus and method are provided for conveying, compacting, and discharging materials such as shavings or swarf in a continuous manner. The material to be compacted is received into a conveyor tube inside which is rotated a screw thread mounted on a shaft. The conveyor tube is formed to have at least one longitudinal passage open to the inside, so that the material being conveyed and compacted does not merely circulate around the outside of the screw thread but is enabled to move longitudinally in a forward direction with a braking effect to facilitate the compaction thereof. In one aspect of the invention, a ratio of the diameters of the outside of the screw thread and the shaft on which the screw thread is provided is less than 3 but not less than 1.
