Abstract
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.
