Abstract

See full text

This disclosure relates to refiner plate segments having feeding grooves having a first width at a first end of the feeding groove, wherein the first end of the feeding groove is disposed closer to an inner diameter of the refiner plate segment, and a second end of the feeding groove having a second width, wherein the second end of the feeding groove is disposed closer to the outer diameter than the first end and wherein the second width is less than the first width. It is believed that the increased width of the feeding groove at the inner diameter, coupled with the change in angle or curve of the feed groove from a feeding angle to a holding angle such that the centrifugal force applied to the lignocellulosic material surpasses the plugging force, allows for improved hydraulic capacity over the refiner plate segment without reducing refining efficiency.
