The end of the rotating shaft 4 is connected to the driving motor 6, and the driving motor 6 is installed on the outer side of the bearing seat 5. The bracket 2 is installed on the base 1, and the rotating shaft 4 is driven to rotate by the driving motor 6. The center of the barrel 3 is eccentric to the center of the rotating shaft 4. A rib 33 is axially installed on the inner wall of the barrel 3, and a material port 321 is opened on the middle wall of the barrel 3 and a sealing cover 34 is installed. One side of the sealing cover 34 is hinged to the material port 321 through a pin shaft, and the other side of the sealing cover 34 is locked with the material port 321 through a locking piece. A limiting pin 7 is inserted on the upper part of the bracket 2 to cooperate with the feeding and discharging of the barrel 3. A limit hole 36 should be opened to match the limit pin 7. The barrel 3 includes a symmetrically distributed lower barrel 31 and an upper barrel 32. The ribs 33 are arranged in the lower barrel 31. The ribs 33 are evenly arranged along the circumferential direction of the lower barrel 31. The material port 321 is opened in the middle of the upper barrel 32. The connection between the lower barrel 31 and the upper barrel 32 is fixed by bolts. A flat feeding tray 8 is provided below the barrel 3. A partition 82 is provided in the middle of the flat feeding tray 8. The partition 82 divides the flat feeding tray 8 into a space. The cavity partition forms an upper chamber 81 and a lower chamber 83, and through holes 821 are evenly processed on the partition 82. The inner diameter of the through hole 821 is larger than the outer diameter of the projectile 12 and the workpiece 11 cannot pass through.

Open the cover, and the mixture of workpieces and projectiles falls along the material mouth to the upper chamber of the horizontal feeding plate. The horizontal feeding plate drives the workpieces and projectiles to move to the outlet on the left. At the same time, the projectiles fall from the through holes on the partition to the lower chamber of the horizontal feeding plate and are separated from the workpieces. The workpieces and projectiles slide along the guide plates at the openings of the upper and lower chambers into their respective collecting boxes, thereby completing the material separation and discharging process.
