  • Patent number: 7059552
    Abstract: These and other objects of the present invention are achieved by a comminution apparatus comprised of a housing member formed with co-planar circularly-shaped chambers in chordal juxtapositioned to each other thereby forming a collision zone therebetween and wherein wheel members having radially disposed directional vanes are positioned for rotation in each cylindrically-shaped chamber and wherein an inlet fluid conduit or a slurry of particulate matter to be treated is in axial fluid communication with each wheel member and wherein each wheel member is caused to be rotated in a direction to accelerate the slurry towards the collision zone and to affect particle size reduction by particle collision and wherein an outlet conduit is in fluid communication with the collision zone for withdrawing a slurry of size reduced particles from the comminution apparatus.

  • Patent number: 7021575
    Abstract: In a waste pulping apparatus, an impeller assembly comprises a rotating blade for pulping solid waste to form a slurry, the rotating blade having an axis of rotation, a base and a plurality of ears that axially extend away from the base. The impeller assembly also includes a sieve ring having axially opposed first and second ends, an inner cylindrical surface and an outer cylindrical surface, where the sieve ring encircles the base of the rotating blade at the first end so that a portion of the ears are radially spaced inside the inner cylindrical surface so that the ears rotate within the sieve ring. A plurality of pumping vanes are also provided for pumping the slurry, where each pumping vane has a pumping surface that rotates radially outside the outer cylindrical surface of the sieve ring. Preferably, the pumping vanes can be easily changed to allow for various head condition while providing a predetermined pumping capacity.

  • Patent number: 6988682
    Abstract: Waste that contains fibers and combustible material is slushed in a continuous-operation high-consistency pulper (10) to suspend in water the fibers contained in the waste. From the pulper (10) are discharged substantially continuously a fiber suspension (P1) through a screen plate; and non-defibrable material (R1) by means of a mechanical transfer device (22). The fiber suspension (P1) is sorted and cleaned for use as raw material in paper or board. The non-defibrable material (R1) and the rejects (R2-R4) separated from the fiber suspension (P1) in the sorting and cleaning stages are used as fuel in energy production and/or utilized as raw material.
