Title: Comminution process to produce engineered wood particles of uniform size and shape from cross-grain oriented wood chips

Abstract

Comminution process of wood chips to produce wood particles, by feeding wood chips in a direction of travel substantially normal to grain through a counter rotating pair of intermeshing arrays of cutting discs arrayed axially perpendicular to the direction of wood chip travel, wherein the cutting discs have a uniform thickness (Td), to produce wood particles characterized by a length dimension (L) substantially equal to the Td and aligned substantially parallel to grain, a width dimension (W) normal to L and aligned cross grain, and a height dimension (H) aligned normal to W and L, wherein the W.times.H dimensions define a pair of substantially parallel end surfaces with crosscut fibers.
