Abstract: Air intake for trash removal apparatus of a cane harvester. The air intake forms the lower portion of the housing of the trash removal apparatus and also serves to guide cane billets into the hopper of a pivotally-mounted billet discharge conveyor. The air intake is formed as a deflectible air permeable curtain of perforated rubber sheeting which avoids both damage to the air intake and jamming of the conveyor during use.

Abstract: A combined vane-rotor separator comprises a rotor, which has upstanding illor baffle rails arranged at the outer periphery thereof. A housing surrounds the rotor to which a feed mixture is supplied in a gas flow from a roll mill and from which the gas and fines leave through a draw-off duct. A cone is located below the rotor and is attached to the housing. A series of guide vanes arranged in a ring is located between the housing and the cone and serves as a guide for the gas flow from the roll mill.

Abstract: The invention relates to a method and apparatus for opening packaged articles, particularly packs and cartons of cigarettes, in which such items are ripped open and broken apart sufficiently to allow the contents, e.g. tobacco, to be separated and recovered. The apparatus aspects of this invention involve a ripper fan, a recycling air leg, and a cyclone separator from which the materials are recovered for further processing.

Abstract: A sample preparation device comprising a wet mill having a lower discharge opening for discharging crushed wet material from the mill. A continuous flow centrifuge is arranged at a lower level than the mill. Flow means provide a direct communication between the discharge opening and the centrifuge for the direct transfer of the crushed wet material from the mill into the centrifuge.

Abstract: A feeding and rationing equipment for mechanical wood pulp, production waste and equivalent comprises a sheet tearing unit, a tearing unit for wood pulp, a distributor unit receiving the pre-flaked and mixed raw-materials from the tearing units. The distributor unit also comprises mixing and rationing devices. The material is transported through a number of cyclones to a feeding unit formed as a vertical pipe with a hinged door receiving blows in the outward direction from a flywheel and camshaft arrangement. The feeding unit feeds the raw-material to mills for further treatment.

Abstract: Waste wood, such as stumps and snag, is treated to make it suitable for the production of paper pulp, whereby the raw waste wood is initially crushed so that part of the bark, sand and stones attached to the wood is detached at this stage already, the obtained crushed material is fed into a washer tank for further washing away bark, sand, stone and peat material from the wood, high-pressure water nozzles being provided at an inlet end of said washer to impinge strong water jets on the crushed wood material, and flow creating means being provided at the lower part of the washer tank to produce a water flow directed slantedly upwards towards an outlet end of the washer tank in order to entrain heavy wood fragments, which may tend to sink into the material leaving the washer tank at said outlet end thereof, said material being further after-crushed and sieved to separate an accept fraction thereof for feeding to a pulp production process.

Abstract: An improved waste material handling system includes a plurality of waste food disposer units which are operable to disintegrate waste food materials to form a slurry. The system also includes a pulper unit which is operable to disintegrate solid waste materials, such as paper, cardboard boxes, plastic bags, etc., to form a slurry. The waste material slurry is conducted from the waste food disposer units and pulper unit to a press which extracts water from the slurry. To prevent the discharge of waste material slurry from an active one of the waste food disposer units to an inactive one of the waste food disposer units and/or the pulper unit, check valves are associated with each of the waste food disposer units and the pulper unit. A pump is also associated with each of the waste food disposer units and the pulper unit to promote a flow of slurry from the units to the press.

Abstract: A device, comprising injectors built in a chamber and directed toward each other, and a separator connected to them through pipelines, each pipeline accommodating a built-in additional separator adapted to withdraw a fraction of the finished product remained in the material to be returned into the injectors for additional treatment.

Abstract: A crusher includes a housing having an internal conduit for directing the advance of material therethrough. A plurality of cooperative pairs of rotatable crush rollers are disposed within the conduit. An endless flexible chain is operatively arranged to rotate each crush roller in a direction to cause material to be advanced through the crusher. Material to be crushed enters the conduit through an inlet and is progressively crushed between the rollers of each successively encountered pair. Crushed material is separated by size and discharged from the crusher via an outlet chute. The spacing between the bottom cooperative pair of crush rollers may be adjusted by selective rotation of a cam member.
