Abstract
Apparatus for use as a portion of a refining surface of a rotatable refining disk is disclosed. The apparatus includes a refining segment having a periphery and being mountable on a rotatable refining disk in juxtaposition with an opposing refiner disk for treating lignocellulosic material in the gap between the disks, and at least one cleaner protruding from the periphery of the refining segment between that periphery and the refiner housing surrounding the refiner whereby lignocellulosic material is cleared from the outer periphery of the refining disk upon its rotation.
