The present disclosure relates to a comminution apparatus including a rotational reducing unit that is rotatable about an axis of rotation. The rotational reducing unit includes a plurality of material reducing components that are mounted to a carrier. The material reducing components are rotated by the carrier in a first direction about the axis of rotation. The comminution apparatus also includes a screen at least partially surrounding the rotational reducing unit. The screen defines a plurality of sizing slots that have slot lengths and slot widths. The slots are elongated along the slot lengths such that the slot lengths are longer than the slot widths.

Apparatus for comminuting fibrous materials

A reducing component is disclosed herein. The reducing component includes a block-style reducer including a height, a width and a depth. The block-style reducer includes first and second ends separated by the height, first and second sides separated by the width and front and back sides separated by the depth. The block-style reducer also includes a first reducing edge that extends across the width of the block-style reducer at a location adjacent to the first end of the block-style reducer. The reducing component also includes a blade-style reducer that projects forwardly from the block-style reducer at a location adjacent the second side of the block-style reducer. The blade-style reducer includes a second reducing edge that extends primarily along the height of the block-style reducer.
