(54) Cut and mill fiberizer


(57) A hard pulp fiberizer housing contains a rotatable disk with axially extending prongs for fragmenting a wood pulp sheet that is fed in through a slot. The radially outwardly centrifuged fragments are engaged between hammer members on the periphery of the disk and a stationary toothed breaker segment where milling action occurs. The fibers are swept around to a screen that is concentric with the disk and through which the fibers are projected into an involute shaped channel for being withdrawn from the housing.
