Abstract: A system for refining lignocellulosic material including a first stator plate segment refining zone and a first rotor place segment refining zone, each of which has grooves. The rotor plate groove width is larger than the stator plate groove width in the inner part of the refining zone, but substantially similar in the outer part of the refining zone.

Abstract: This disclosure relates to a refiner plate segment, mechanical refiners, and methods to manufacture a refiner plate segment having one or more water channels disposed in a variable substrate profile along the radial length of a refiner plate segment base and disposed between the refiner plate segment inlet and the primary refining section, wherein the variable substrate profile comprises an undulating curve configured to complement a second undulating curve on an opposing refiner plate, and wherein dimensions of the one or more water channels are sufficiently narrow to prevent wood chips from entering the water channels and sufficiently wide to provide a bypass path for the free water.

Abstract: A set of plate segments for refining comminuted cellulosic material including: a first plate segment and a second plate segment, wherein the first plate segment and the second plate segment each have a refining side configured to oppose the refining side on the other segment, and each of said refining sides includes a refining zone having bars and grooves between adjacent ones of the bars, wherein distance between the grooves in the first plate segment and the grooves in the second plate segment is substantially constant along an arc through the refining zone while the set is mounted to discs in a refiner.
