    Abstract: A disperser apparatus includes: a first disperser assembly configured to rotate around an axis; and a second disperser assembly facing the first disperser assembly. The first and second disperser assemblies each have a plurality of disperser-refiner plate segments annularly arranged. Each of the disperser-refiner plate segments includes a substrate having teeth extending from the substrate and arranged in rows disposed at radial intervals defining a dispersion section. Each tooth has a tooth height; and walls; and edges at junctions of adjacent walls. Each of the disperser-refiner plate segments further includes a refining section of refiner bars extending from the substrate, wherein adjacent refiner bars and the substrate define a groove between the adjacent refiner bars; and a plurality transition bars disposed between radially outermost teeth and the refining section.

    Abstract: Refiner plate elements for a conical mechanical refiner include: a rotor plate element including at least one rotor plate segment having a feedstock inlet opening disposed at a first end of the rotor plate segment; and a rotor plate segment refining area disposed between the feedstock inlet opening and a second end of the rotor plate segment. The refiner plate elements may further include: a stator plate element including at least one stator plate segment having a stator plate segment refining area; and first and second attaching rails configured to couple to the stator plate segment to a stator support frame of the conical mechanical refiner. A separation between the first attaching rail and the second attaching rail that is not covered by the stator plate segment is configured to form a feedstock outlet opening.

    Abstract: Refiner plate segments for a conical refiner may include a rotor plate segment having inlet openings disposed at one or more inlet locations on the rotor plate segment, and a stator plate segment having outlet openings disposed at one or more outlet locations on the stator plate segment. The rotor plate segment is disposed opposite the stator plate segment such that the one or more rotor plate segment refining areas and the one or more stator plate segment refining areas oppose each other, and the one or more inlet locations and the one or more outlet locations are separated by one or more refining zones formed by the rotor plate segment refining areas and the stator plate segment refining areas.

    Abstract: The problem of increased energy usage in refiners over the working life of a refining assembly is mitigated by the use of a refiner plate segment having a refiner side and a back side distally disposed from the refiner side, refiner bars engaged to a substrate of the refiner side, wherein the refiner bars have a refiner bar height, and wherein adjacent refiner bars and the substrate define grooves between the adjacent bars, and protrusions disposed in the grooves, wherein the protrusions have a protrusion height, wherein the protrusion height is 30% or less of the refiner bar height.

    Abstract: A rotor cap assembly has been conceived using multiple wedge-shaped rotor cap segments, in which the cap segments are disposed on a cap segment retainer and in which the cap segment retainer pilots the multiple rotor cap segments at a diameter intermediate the cap segments' outer diameter and the cap segments' middle diameter. By piloting multiple rotor cap segments with retaining means on the cap segment retainer and positioning means on the multiple cap segments, the rotor cap segments and cap segment retainer assembly may be fixed to a plate holder or directly to a rotor disc of a refiner without substantially altering either the plate holder or the rotor disc.
