Abstract: Apparatus for separating components of post-consumer carpet—pile, adhesive, and primary/secondary backings—may initially comprise spectrographic face fiber identification. Separating substantial portions of pile from backing comprises feeding carpeting into a rotating pinned drum, with separated pile U's dropping, while a residual composition, being primarily backing, travels with the drum, to be separated therefrom using vacuum pressure, with the composite backing being sent to a press. Vacuum pressure delivers the separated U's to a spinning perforated squirrel cage to remove dislodged pieces of adhesive, by vacuum pressure applied to an interior top portion of the cage to draw pieces therein. Rotating the perforated squirrel cage, which is sealed on the exterior using a belt, permits the U's to drop into a hopper. A mesh shaker box vibrates to separate any remaining backing from the pile U's. Hammers in a fibermill remove remaining adhesive attached to the separated pile U fiber.

Abstract: The method and a device is for the dilution of dewatered cellulose pulp that maintains a consistency of 20-30% or greater. By shredding of the pulp to a finely divided dry-granulate, dilution to a homogeneous consistency in the medium consistency range can take place exclusively through hydrodynamic effects from the addition of dilution fluid. The dilution fluid is added to granulate at a position at which granulate is in free fall in a standpipe and above a level LiqLEV of diluted pulp in the standpipe. A number of nozzles are arranged around the periphery of the stand pipe, directed in towards the centre of the stand pipe, obliquely downwards in the direction of fall of the granulate. It is possible through this simplified procedure to avoid completely the conventional dilution screws, and this reduces the investment costs and operating costs, while at the same time unnecessary mechanical influence of the pulp fibres can be avoided.
