    Abstract: A comminuting rotor is driven by a rotary current electric motor via a non-positive traction drive, wherein said rotary current electric motor is energized by a controlled frequency converter for operating the comminuting rotor at a predetermined rotational speed during the normal operating phase. A degree of slip of the traction drive is determined and monitored and the rotary current electric motor is controlled for being powered off if a first slip threshold value is exceeded. If a predetermined second threshold of the traction drive slip is exceeded, which is below said first slip threshold, for continuing the operation of the comminuting device, the frequency converter is controlled in a slip operating phase for a closed or open loop control of the traction drive slip to a predetermined third slip threshold value and for reducing the torque output from the rotary current electric motor.

    Abstract: An adjustable screen apparatus for a material destruction device includes a first stationary fixed member and a second member positioned in an operatively juxtaposed and nesting relationship for reciprocal movement relative to the first member, each having a predetermined plurality of openings which are disposed in a predetermined pattern. A guide system is provided for guiding the reciprocal movement of the second member relative to the first member. A power operated drive is coupled to a source of power and to the second member for reciprocally moving the second member between a first position wherein each opening in the second member substantially overlaps a respective opening in the first member for producing large size particles and a second position wherein each opening in the second member partially overlaps each of a pair of adjacently disposed openings in the first member for producing small size particles.

  • Patent number: 7832666
    Abstract: Apparatus for destruction of articles and any information associated therewith. Embodiments include an article-destruction chamber and a rotating head for repeated striking of articles and article fragments in the chamber. The head includes a body portion and a shaft. The body portion has plural striking elements extending radially outward therefrom. Each striking element has a forward-facing radial striking surface with an area. High-speed rotation of the head causes the striking surfaces to violently contact and destroy articles and article fragments in the chamber and to render any associated information unusable.

  • Publication number: 20100193620
    Abstract: A chipper mounted aerial unit for tree trimming and removal includes a truck having a cab and bed frame. An aerial unit including a hydraulic arm and lift bucket are attached to the bed frame. A chipper unit is attached at and end of the bed frame opposite the truck cab, and has a feed chute angled with respect to a discharge chute, the discharge chute being in substantial alignment with a main longitudinal axis of the truck. A chip box trailer is connected by means of a hitch to the bed frame and is positioned to receive debris in the form of chipped wood and the like from the discharge chute of the chipper. The chip box trailer may be quickly removed from a hitch on the bed frame and transported to a disposal area by another vehicle, while another chip box trailer is positioned for continued receipt of debris from the chipper, minimizing down time and improving operator safety by allowing the operator to stand out of the roadway while feeding the angled feed chute.

The rotor assembly is made up of a central driven shaft journaled for rotation in the frame of the tree cutting attachment. Circular endplates are disposed proximately on the opposed ends of the central driven shaft. Two diametrically opposed rows of regularly spaced-apart semicircular support plates extend between the circular end plates. The semicircular support plates are held in parallel-spaced relationship by a plurality of equally circumferentially spaced bars extending between the endplates. Swinging hammers are mounted for free pivotal movement in an alternating pattern between the support plates. Each hammer includes a main shaft extending between the support plates, a body member pivotally connected to the main shaft at the pivot axis parallel to and spaced from the central driven shaft and a generally flat tooth member extending radially outward from the body member.
