ABSTRACT:
Apparatus for refining pulp stock which is ground in an inclined grinding zone extending from a peripherally outer portion of a pair of opposed disc members which rotate relative to one another within a housing. The pulp stock is advanced by a conveyor into a central opening between the opposed disc members, from which opening it is accelerated radially towards the grinding zone under the influence of the centrifugal force generated by the rotational movement of the disc members by means of a plurality of sector-shaped channels defined between the opposed disc members.
