  • Patent number: 7267293
    Abstract: A high efficiency bowl mill (100) is provided by the present invention. Included in the high efficiency bowl mill (100) is a plow (185) that is downstream of a grinding roll (180) on a grinding surface (145). The plow (185) loosens material that has been compacted by the grinding roll (180). Also included is a deflector (165) that redirects an air stream so as to pick up material loosened by the plow (185) and deposit material requiring further grinding. An outlet (201) of an inverted cone (200) is positioned so as to deposit material for pulverization on the grinding surface (145) and to restrict the air stream from entering the inverted cone (200).

  • Patent number: 7234659
    Abstract: An automatically swiveling crushing apparatus has a swiveling motor in a bracket, and branches diverged from charging and discharging paths that constitute the hydraulic piping leading to a cylinder for closing or opening distal crushing arms. One of the branches extends from one of the paths then operating to open the end arms, so that a portion of the hydraulic fluid is fed to the hydraulic motor if and when internal pressure in this branch has exceeded an upper limit. The other branch extends from the other path leading to the cylinder so as to close the end arms, and this branch prevents any amount of hydraulic fluid from flowing back to the motor. The branches render dispensable a discrete or independent hydraulic piping in a self-propelled platform having a proximal working arm to be connected to the apparatus, saving cost and labor in connecting this arm to the apparatus.

  • Patent number: 7234656
    Abstract: A paper shredder paper feed mechanism, characterized in having a paper insert opening structured from two movable paper feed tubes, which are configured above paper shredding cutters. Two ends of each of the paper feed tubes are respectively positioned in W-shaped embed grooves of positioning plates of a frame. The two paper feed tubes are ordinarily closed together, thereby enhancing safety and preventing dust and miscellaneous objects from falling into the paper shredder. When paper is inserted into the paper insert opening, the thickness of the paper opens the two paper feed tubes, thereby guiding the paper smoothly guided into the paper shredding cutters.
