Wood chips are debarked by compacting them in a mass, and agitating the compacted mass. In the compacted mass the chips are caused to rub against one another so that the bark is removed from the chips by rubbing friction of chip against chip. Frictional pressure on the removed bark finely comminutes the bark for easy separation from the debarked chips. The compacting and agitating of the chip mass is effected by a rotor device in a debarking drum chamber.
