  • Publication number: 20030164098
    Abstract: A metal chip and shaving compactor includes a compaction housing (80) having a compaction chamber (82) with a compaction piston (64) extending into the chamber Metal chips and shavings are admitted to the chamber through an inlet opening (84). Separate ball screw drive mechanisms (50 and 92, 94) move the piston and the compaction housing along an axis (58) between positions where each is either proximal or distal from the base (30) Independent operation of the ball screw drive mechanisms permits metal chip and shaving to be admitted into the chamber, compacted and subsequently discharged as compacted puck-like pellets Computer controls (162) operate the ball screw drive mechanisms and sense (182, 184, 186) operation of the compactor based on rotational positions of the screw drives of the ball screw drive mechanisms.

  • Patent number: 6572037
    Abstract: A shredder for shredding metal shavings, chips and the like includes a housing (10) containing a shredder assembly having first and second roller motor-operated shafts (40,42) carrying spaced knives (50) for shredding metal. A sensor (66,68) on at least one shaft (40,42) senses a change in rotation of the shaft, indicative of a jammed condition. A microprocessor (70) responds to the sensor to open an ejection door (20) normally closing an ejection outlet (16) and to reverse rotation of the shaft (42) to dislodge the jamming object. When the jamming object is dislodged, the microprocessor halts rotation of one shaft (40) to permit the knives on the reverse rotating shaft (42) to carry the jamming object toward the open ejection outlet (16). After the object has been ejected, the microprocessor (70) returns the shafts (40,42) to their normal operation to continue shredding metal.

  • Patent number: 5664492
    Abstract: A metal shavings and chips compactor for extruding oil from metal chips and shavings and compacting the metal into easily transportable pellets. A compactor cylinder contains a piston and has an opening through which an auger feeds metal chips and shavings. A gate doses an end of the cylinder. A first hydraulic drive drives the piston under low pressure to close the opening and apply a first compacting pressure on the metal to form a loosely compacted pellet in the cylinder. High pressure then operates the piston to form a compact metal pellet substantially void of interstices. A second hydraulic drive opens the gate; the piston is operated at low pressure to discharge the compact metal pellet from the chamber and oil is collected below the cylinder. The compacting pressures are achieved through mechanical advantages provided by the size of the piston to that of the first hydraulic drive.
