A cutting blade assembly including a cutting plate, a plurality of cutting slots formed in the cutting plate, and a cutting hub. The cutting plate includes an axial face and a central opening. The plurality of cutting slots are circumferentially spaced about the central opening. Each of the plurality of cutting slots intersects the axial face and defines a respective axial cutting edge at an intersection of each of plurality of cutting slots and the axial face. Each of the plurality of cutting slots defines a base surface that is nonparallel to the axial face. The cutting hub is positioned in the central opening and has a cutting arm adjacent to the axial face.

There is provided a refining device including: a casing; a rotor having a rotation shaft, a first rotor portion positioned on a charging port side, a second rotor portion positioned on a discharge port side, and a partition wall, and disposed on an inside of the casing; and a liner disposed on an inner surface of the casing along an outer periphery of the rotor, in which the first rotor portion has a plurality of first blades radially installed around the rotation shaft through a gap portion which is open on the charging port side and blocked by the partition wall, the second rotor portion has a plurality of second blades radially installed around the rotation shaft, and in a state where the rotor is rotating, the raw material charged from the charging port is refined when sequentially passing between the gap portion and the adjacent first blades and when sequentially passing between the first blade and the liner and between the second blade and the liner, and is discharged from the discharge port.

An apparatus for recycling material which includes: a housing; typically at least two levels of cutters each having at least two roller cutters, which may be configured to slide and create variable gap to accommodate materials of varying sizes. A weight sensor; a fill sensor; and a camera may be provided, wherein various data is transmitted to a central data hub enabling recycle bin pickup synchronization and determining quality of shredded materials. The roller cutters on different levels typically have a plurality of cutting blades, wherein the shape on each of the levels may be different. The first and second level are typically fixed to the housing and material shredded by the first level proceeds to second level which is then shredded by the second level before being discarded into recycle bin. Another level of at least two roller cutters with a different shape may be part of the apparatus.

There is provided a refining device in which a first rotor portion has a plurality of first blades radially installed around a rotation shaft, a second rotor portion has a plurality of second blades radially installed around the rotation shaft, in a state where a rotor is rotating, a raw material charged from a charging port is refined when sequentially passing between a liner and an end portion on an outer peripheral side of the first blade and between the liner and an end portion on an outer peripheral side of the second blade, and is discharged from the discharge port, and D1>D2, where a separation distance between the liner and the end portion on the outer peripheral side of the first blade is D1, and a separation distance between the liner and the end portion on the outer peripheral side of the second blade is D2.
