Abstract: A disc screen apparatus has a generally V-shaped configuration with a lowermost region that provides a trough and a pair of vertically inclined regions. Mixed recyclable materials deposited onto the trough are agitated and classified with different types of material falling through the discs of the trough, falling off one end of the trough, and falling off upper terminal ends of the inclined regions.

Abstract: For sieving biocompatible adsorbent beaded polymeric materials a column is filled with beads, a fluid is supplied into the column upwardly, a screening element located in the column between a bottom of the column and a top of the column so that beads below a predetermined threshold are displaced by the fluid flowing upwardly and through the screening element, while beads above the predetermined threshold are retained under the screening element, and another fluid is supplied downwardly so as to prevent clogging of said screening element and to agitate the polymeric beads in the column under the screening element.

Abstract: A sifting machine comprises a stationary sifting basket, a rotor rotating within the sifting basket and a worm conveyor feeding into an end of the sifting basket for dosing and introducing the material to be sifted. The rotor and the worm conveyor are driven for rotation, wherein, in order to achieve an optimal rate of revolution adjusted to the desired mode of operation for both the worm conveyor and the rotor, each has its own drive device. In order to facilitate removal, the unit comprising the rotor, the sifting basket and the associated drive mechanism can be axially removed from the sifting machine housing and subsequently pivoted-out in a sideward direction via a pivot bearing.

Abstract: The novel invention proposes a final screen which is very reliable in operation and which is suitable more particularly also for building into a pneumatic conveying line. In a first section the material is distributed uniformly over the entire peripheral surface of the screen shell. The subsequent section is used for completing screening and separating the coarse material out through an outlet. A centrifuging rotor with helically arranged elastomeric cleaning lobes projecting from the centrifuging bars provide a high throughput and particularly damage-obviating discharge of even relatively large foreign bodies.

Abstract: A manure separating apparatus includes a trough with angularly bottom surfaces that converge downwardly to a discharge opening. A drain screen is located above the bottom trough surfaces and includes somewhat similarly angled downward converging infeed and discharge surfaces. The infeed section of the drain screen is approximately twice as long and at a smaller angle to the horizontal than the discharge screen section. A manure/liquid slurry may be introduced at a top infeed end of the screen and moved downwardly along the infeed section of the screen by a paddle conveyor. Separation of solids occurs primarily along the infeed screen section. The slurry is then moved angularly upwardly along the discharge section of the screen for final dewatering. The discharge section is spaced above the trough bottom to avoid liquids on the trough bottom below to facilitate dewatering of the solids before discharge.

Abstract: A method and apparatus for removing from soil particles within a predetermined size range, comprises a movable frame, and a digger attached thereto to excavate soil as the frame is moved. A first separater to which the excavated soil passes allows material of less than a first predetermined size to pass through and discards material of size greater than said first predetermined size. A second separater is adapted to retain material of size greater than a minimum of said predetermined size range and to discard material of size less than said minimum. The retained material is stored.

Abstract: A separating apparatus employs a foraminous drum with a resilient belt forming a nip therebetween. A take-up roller upstream of the nip is rotatably supported about a center of rotation that is parallel to, but offset from a central axis of the take-up roller. As the wobbling roller rotates, it constantly changes the point on the circumference of the foraminous drum at which contact is made with the resilient belt. This overcomes a tendency for entering items to bridge the nip.

Abstract: Apparatus for the separation of mixtures of materials of different consistencies, such as meat and bone, or sewage containing solid material, comprises a positive displacement pump feeding the pressurized mixture to a separator which can be separate from the pump or an integral part of its structure. The pump comprises a rotary vaned pump with radially-moving vanes of fixed length operating with both their ends always in sealing engagement with the wall of an internal cam also constituting a wall of the pump chamber. The vanes are provided with cutting edges able to shear material such as bone that enters the pump, so that the pump is not jammed thereby.

Abstract: An automated wet sieving apparatus and process are provided comprising a wetting liquid distributor which is coupled by eccentric disks to a motor which drives the distributor in an orbital path for supplying the liquid onto a sieve. Means are provided for creating alternating vacuum and pressure below the sieve. The vacuum draws undersized particles whose size is being determined through the sieve and the pressure loosens blinding particles from the sieve. Preferably, the sieve is cyclically tilted as the wetting liquid is being distributed onto the sieve.

Abstract: An improved system for the production of digested pulp from wood chips and knots which includes a separating apparatus, connected to the digester output, capable of separating knots from partially cooked wood chips and fibers at the digester pressure and consistency. The separated fibers and fiber bundles pass to a refiner where the fiber bundles are mechanically reduced to fibers in a liquid environment at a high consistency and at the digester pressure. The knots are then re-cycled to the digester or other processes.The separating apparatus above uses a plurality of rotating members such as intermeshing screws or grooved rolls, arranged in a vertical screen to separate an inlet chamber from an outlet chamber. Knots cannot pass through the rotating members and thus are driven out of an outlet which communicates with the inlet chamber. The fibers, however, do pass through the rotating members to the outlet chamber and exit therefrom by a second outlet.

The bottom end of the stator is partially open to communicate with a feed hopper while the upper end, along with the cylinder, is subject to spray nozzles. A recirculation system conducts liquid from the bottom to the top of the tank.
