A method and apparatus for grinding pulpwood and/or wood chips, in which the force urging the wood against the grinding surface arises centrifugally and utilising this force to promote uniform and pressurised water spray against the internal grinding surface. The grinder (10) includes a cylindrical internal grinding surface (22) and a coaxial rotor (28,30) the rotor having a central cavity and defining at least one pocket through which material in the central cavity can contact the grinding surface and means for applying water to the grinding surface. |
