Abstract:
1. A rotor configured to treat waste or recycled material, comprising; a rotor housing having a center axis and configured to receive a material; an inner deflector wall within the rotor housing configured to rotate about the center axis, wherein rotation of the deflector wall decomposes the materials into components, the rotation of the deflector wall causes the material to move in a substantially helical transport path in a first direction; an outer deflector wall concentric with the inner deflector wall and separated by a gap in which the material moves between the inner and outer deflector walls, the inner and outer deflector walls each including at least one protrusion extending therefrom toward the gap and offset from one another, wherein the material decomposes upon striking the protrusions; and a port configured to inject process air into the rotor housing, wherein the air moves in a substantially helical airflow path in a second direction opposite to the first direction.
