Abstract

Pulp stock, such as wood chips, sawdust, bagasse and the like is refined in a disc mill having a pair of axially-adjustable relatively rotatable discs in a closed housing. The grinding space 34 between the discs comprises an inner grinding zone which extends in a plane substantially perpendicular to the axis of rotation of the discs and an outer grinding zone which merges with and extends at an angle to the plane of the inner grinding zone. The outer inclined grinding zone is defined between a rotating disc member 12 and a correspondingly inclined grinding surface of a stationary element of the other disc member and is adjustable to vary the width of the outer grinding zone. The angled portion of the rotating disc member is provided with exhaust passages or channels 76 for evacuating steam from the pulp stock as it is being ground in the inclined outer grinding zone. The steam and stock may be separated by dividing the grinding chamber with a seal ring 82. <IMAGE>
