ABSTRACT:
Scrap metal chips, which may be oily, wet and dirty and which may be of varying lengths and widths, twisted, curled and cracked, resulting from machining metal articles, are cleaned and dried by passing them sequentially through a washer cylinder, a rinse cylinder and a dryer cylinder. A thread formed of a plate-like metal strip is secured within the interior surface of each cylinder to provide a deep, spiral trough within each cylinder. Each cylinder is rotated so that the chips are moved, in a tumbling motion, along the troughs due to the auger-like thread, from one end to the opposite end. A hot, aqueous washing solution is flowed through the washer cylinder in a direction opposite to the movement of the chips. Similarly, a hot rinse water is flowed through the rinse cylinder in a direction opposite to the movement of the chips therethrough. Hot air is flowed through the dryer cylinder along its central axis and then, radially outwardly of its axis, for impinging upon and drying the chips moved along the dryer cylinder.
