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.

Abstract: A flinger or refiner plate for a mechanical refiner including deep notches or holes in feeder bars of the flinger plate and/or open passages or holes in bars of the refiner plate. The open passages and/or holes in the bars significantly reduce stagnate flow zones at the trailing side of the bars during operation of the mechanical refiner. The reduction of the stagnate flow zones may reduce or eliminate fiber accumulation at the trailing side of the bars.
