Abstract: A system for treating cellulosic fibers to improve paper, board and tissue quality; the system involves splitting fibers into an original portion having original fibers and a refinable portion. The refinable portion may further be fractionated by one or more fibers properties by a fiber fractionation system into a first fraction and a second fraction. The refinable portion as a whole, or a fractionated fraction thereof, is then refined to produce refined fibers. Varying amounts of the original unrefined fibers, refined fibers and possibly additionally fractionated unrefined fibers are blended together to form an optimized slurry that is processed by a paper machine into an optimized paper product. A master control system, fiber measurement system and optional fractionation maintenance system are integrated with the overall system to regulate all processing.

Abstract: A hybrid method for processing papermaking fibers to remove high density stickies typically includes utilizing a multistage array of forward cleaners coupled with a flotation cell which increases overall efficiency of the system. In a preferred embodiment, a first rejects aqueous stream from a first stage bank of centrifugal cleaners is treated in a flotation cell before being fed to a second stage bank of centrifugal cleaners. With the improved technique, the accepts from the first stage bank of centrifugal cleaners may be combined with the accepts from the second stage bank of centrifugal cleaners and fed forward to a thickening device, for example. The technique is also suitably employed for removing stickies from material which has already been screened with a fine screen.

Abstract: The conventional infeed head and inverted cone of a Uniflow cleaner are connected by a generally cylindrical channel dam segment which has an annular inwardly extending channel dam. The narrow end of the inverted cone is connected to a separation body through which a vortex finder extends into the inverted cone. The light reject particles are removed from the input flow through the vortex finder. Accepts and heavy rejects flow into an inverted hydrocyclone chamber within the separation body defined between an outer cylindrical ring and an inner cylindrical ring and the vortex finder. An annular heavy rejects chamber is defined exterior to the outer ring, and fluid is drawn off tangentially therefrom. Accepts flow downwardly though the inner ring into a bowl beneath the separation body, where they are removed from an accepts outlet. The cylindrical or concave surfaces of the separation body are economical to manufacture.

Abstract: The present invention relates to a method and an arrangement in a fibre reclaimer for cleaning of heavy and light contaminate particles from a fibre suspension and said fibre reclaimer comprises at least a vessel (4) having an opening (15) which via a connection arrangement (1, 2) is connectable to a cyclone. The connection arrangement consists of a cone (1) having an outlet (13) with a predetermined diameter (d) and is inserted and located in a conical mantle (2), which with its free end part (14) is fixed to the opening (15) of the vessel (4), whereby the opening (13) is situated a predetermined distance (A) from the opening (15). The vessel (4) has a suction pipe (3), which with its opening (16) having a predetermined diameter (D), is concentrically situated in the opening (15) for forming a ring shaped opening gap (17) between the pipe (3) and the vessel (4) and which pipe (3) extends downwardly in the vessel ( 4) or adjacent vessles to terminate with its other tail end (18) a predetermined distance from the bottom of the vessel, said distance is depending on if light or heavy contaminate particles shall be separated from the fibre suspension. The method for cleaning of a pulp suspension concerns to achieve a vacuum in the lower part of the cone (1) to resuck pulp suspension from the vessel (4) through the pipe (3), cone (1) and into the cyclone.
