  • Patent number: 7322538
    Abstract: Slag crusher having a shaft extending through a pressure housing which shaft is provided with inlet baffle plates in a funnel-shaped arrangement, stationary cutting knives and cutting knives rotating on the shaft. The shaft is offset with respect to the vertical center line of the pressure housing, so that the crushing area is concentrated in the middle of the slag crusher. The rotating cutting knives are angularly offset on the periphery of the shaft, so that only one rotating knife and two stationary knives are in engagement at a time.

  • Patent number: 7311279
    Abstract: A self cleaning cutting assembly is provided, having an array of counter rotating cutters in which a plurality of cutters rotating in a first direction are mounted on a first shaft and a plurality of second cutters are mounted on a second shaft for rotating in an opposite direction. The array of cutters is provided with a plurality of clearing or cleaning rings located alternately with the cutters on each shaft. The cutting array is kept clear of debris or partially cut material by movement of the clearing or cutting rings against adjacent cutters. Movement of the clearing or cleaning rings is a combination of rotary motion and linear motion, in which the linear motion is imparted by the cutter located opposite the cleaning ring striking the cleaning rings so as to push the cleaning ring beyond the position of the widest part of the cutter to completely dislodge material from the cutter.

  • Patent number: 6938845
    Abstract: A sewage cleaning and comminuting system is provided with a pair of dissimilar sized cutter stacks that extends across an influent channel which intercepts all solids too large to pass there through. The dissimilar sized cutter stacks are capable of grinding large and round shaped objects. The cutter stacks rotate at dissimilar speeds and require less energy to grind solids than other grinders having similar sized grinders rotating at the same speed. The system includes an integrated cleaning assembly whereby debris accumulated between the cutter disks is removed as the cutter disks rotate. Embodiments are provided including grinders that employ three and four shafts. Another embodiment is directed to an improved cutter disk. Yet another embodiment includes an auger screen assembly used in conjunction with the comminuting system to remove solids from the effluent stream.

  • 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.
