Abstract
A refiner plate segment for a refiner including opposed first and second refiner plates has radially inner and outer ends, multiple radially disposed bars, and grooves alternating with the bars. The base of at least one of the grooves has a variable base profile along the radial length of the base such that in at least one radial position between the inner and outer ends of the refiner plate segment, the base profile of the refiner plate segments of the first refiner plate has a low point and the base profile of the refiner plate segments of the second refiner plate has an oppositely disposed high point. The high point in the base profile forces lignocellulosic material carried on the second refiner plate onto the first refiner plate.
