• a vertically provided separation bin, a CRS guide device, and a CRS distribution plate, wherein the CRS guide device and the CRS distribution plate are arranged in the vertically provided separation bin;
• the CRS guide device comprises a guide plate and a throwing roller;
• the guide plate of the CRS guide device is in the shape of a triangular prism, the triangular prism having a first rectangular surface provided with an inwardly concave arc surface which receives an arcuate surface of the throwing roller provided on an upper portion of said throwing roller and a second rectangular surface provided adjacent said inwardly concave arc surface and formed as a guide surface;
• said guide surface being adjustable at an angle relative to a horizontal plane and the CRS distribution plate is arc-shaped and evenly provided with multiple air vents;
• and
• a CRS feed port is provided above the CRS guide device;
• the guide plate of the CRS guide device is provided on an upper portion of a side of the throwing roller, such that the guide surface guides CRSs fed through the CRS feed port to the arcuate surface of the throwing roller;
• a suction port is provided above the CRS distribution plate and is connected to an external suction fan;
• and the CRS distribution plate is provided under a side of the CRS guide device with a concave arc surface facing and positioned across from the CRS guide device and the throwing roller on an opposing wall of said vertically provided separation bin.
