The auxiliary powerfeed features a rotating drum on which are mounted rigid tines (or teeth) arranged in a staggered pattern. The drum is rotationally mounted within a pivotally mounted lift arm. The lift arm holds the axial shaft of the drum at each end. A set of hydraulic cylinders is mounted to the lift arm, one on each end of the drum. During operation, as a bale or other object comes into contact with the auxiliary powerfeed, the drum automatically lifts until it reaches the top of the object, the limit of its lift path, or a predetermined height that optimizes efficacy for a particular application. In some cases, the auxiliary powerfeed automatically operates differently with different feedstock consistencies.

Since the capacity of the hydraulic motor is switched to the large capacity when the feeder is stopped, it is possible to crush wood in the crusher with high torque and to reduce the load in order to recover to a former state in a short time.

One embodiment includes: a bale support member for supporting a bale of pulp, the bale support member defining two openings; two rotatable fiberizing assemblies having disrupting elements protruding through the openings an adjustable distance above the bale support member to contact a surface layer of the bale of pulp, the surface layer having a dimension parallel to the longitudinal axis of the fiberizing assembly, a transportation assembly for moving the bale of pulp back and forth along the bale support member and over the openings so that the disrupting elements contact a surface layer in the bale, an adjustable reciprocating assembly permitting adjustment of the frequency by which the transportation assembly moves back and forth over the opening.

  • Patent number: 6517019
    Abstract: A tub grinder is used for grinding industrial wastes, including large stumps, lumber chunks and the like. A cover member is pivoted alongside the tub, and is made in two sections. An upright frame section is pivoted near a plane along the bottom of the tub, and extends upwardly to a level at or adjacent to the top of the tub. A cover section is pivotally mounted to the upright frame and can be adjusted about a generally horizontal axis from a generally horizontal position to an upwardly extending position. The upright frame can be tilted outwardly so that the cover section is out of registry with the tub to permit the tub to be loaded.

  • Patent number: 6454195
    Abstract: The invention relates to an industrial waste crushing bit capable of sufficiently exerting wear resistance from the initial stage of service and improving the service life at low cost. A super-hard member to be inserted in an opening formed in the tip of a bit body is formed into a plate shape and is secured to the bit body in such a manner that the plate faces of the plated-shaped super-hard member are placed in a direction virtually orthogonal to the rotational direction of the bit, with its side being exposed.

  • Patent number: 6412715
    Abstract: A tub grinder includes a tub mounted for rotation about a vertical axis. A grinding member is positioned within a floor of the tub grinder. A deflection plate partially covers the floor to define a narrow trajectory area for debris being ejected from the tub. A deflection cover is secured to the frame covering the tub opening only over the deflection area.

  • Patent number: 6261410
    Abstract: Process and apparatus for separating compressed material containing paper fibers where the apparatus includes at least three hammer rollers arranged essentially in a same plane and each hammer roller includes rotatable hammers. The process includes rotating the rotatable hammers, transporting the material over the at least three hammer rollers in a transport direction essentially parallel to the plane and transverse to the axes of the rollers, breaking up the material into fine material and non-fine material, and separating the fine material from the non-fine material by allowing the fine material to pass through gaps formed between the hammer rollers. The apparatus includes a machine frame and a plurality of rotors arranged next to one another in the machine frame. Axes of the driven rotors are arranged to lie in at least one plane, and the rotors are positioned to form free gaps between the driven rotors.

  • Patent number: 6260778
    Abstract: An improved tub grinder includes a hammer mill having a swing diameter which is adjustable. The tub grinder includes: first and second sets of interchangeable hammers, the second set being shorter than the first; first and second interchangeable semi-cylindrical screen assemblies, the second screen assembly having a smaller diameter than the first; and a pair of shear bars and adapter plates. In a first configuration, the first set of hammers are mounted to a rotor assembly and have a first swing diameter. The first semi-cylindrical screen assembly is secured within a cylinder box in co-axial alignment and outwardly spaced relationship with the first set of hammers. The shear bars are mounted to the tub floor and extend across the sides of a floor opening in spaced relationship to the swing diameter of the first set of hammers to form a gap therebetween.
