Abstract

A method and apparatus is disclosed for refining lignocellulose containing material in which a gaseous medium is present. In accordance with this method and apparatus, the lignocellulose material is refined between a pair of opposed inner and outer refining surfaces by rotating the refining surfaces in opposite directions along a common axis. Gaseous flow paths are provided along the inner refining surface to provide for sufficiently uniform gaseous flow therealong during refining to avoid a stoppage of gaseous flow to an extent which would result in deleteriously affecting the material being treated. The refining surfaces are angularly disposed relative to the common axis such that, during refining, the material being treated is urged by centrifugal force against the outer refining surface to affect simultaneously the desired refining of the material and the flow of gaseous medium along the flow paths to avoid deleteriously affecting the material.
