Abstract: Refiner plate segments and refiner plates having fully dammed or partially dammed grooves on a major surface that may control flow behavior of lignocellulosic materials passing between refining plates in a refiner. The dammed grooves form groove segments, and each groove segment has a length of no more than about 30 mm or a subrange thereof.
