A system is disclosed. The system includes an impact processor comprising an inlet and an outlet, a secondary classifier comprising an inlet and an outlet, the secondary classifier being downstream of and coupled to the impact processor, a recirculation mixer valve downstream of and coupled to the outlet of the secondary classifier, and a recirculation line coupling the outlet of the first secondary classifier to the inlet of the impact processor.

An abrasion resistant wear plate is mountable within a rotor or a vertical shaft impact crusher to protect the rotor from material fed into the rotor. The wear plate includes a main body that mounts and supports at least one abrasion resistant insert to define, in part, a contact face over which feed material is configured to flow.

A bi-directional rotation feed roller for tree processing devices preferably includes a drive wheel, a drive disc, a plurality of reinforcement rings and a plurality of reinforcement plates. The drive wheel includes a drive cylinder and a plurality of media engagement thumb nails attached to the drive cylinder. The plurality of media engagement thumb nails are preferably arranged in a plurality of rows. A side wall of the plurality of media engagement thumb nails are preferably angularly offset from a lengthwise axis of the drive plate. The drive disc is attached to the drive wheel in substantially a middle of a with thereof. The plurality of reinforcement rings are attached to an inner perimeter of the drive wheel. The plurality of reinforcement plates are attached to an inside perimeter of the drive wheel between the drive disc and one end of the drive wheel.
