A transmission shaft 9 is rotatably connected between the two symmetrically arranged adjustment blocks 18, and a crushing roller 15 is installed on the transmission shaft 9. On both sides of the inner bottom of the machine shell 1, a return material cavity is formed. A lifting pipe 5 is vertically installed inside the return material cavity, and the upper end of the lifting pipe 5 extends above the machine shell 1. A feed pipe 4 is installed in the middle of the top surface of the machine shell 1. A return material pipe 7 is fixed on the outer wall of the feed pipe 4. The return material pipe 7 is inclined and its end is connected to the lifting pipe 5. The lifting pipe 5 lifts the large-particle material and re-enters it into the machine shell 1 through the return material pipe 7 for the next crushing, which can improve the uniformity of the crushed material.

[0022] Further improved, support frames 13 are respectively installed on both sides of the inner bottom of the machine shell 1. A screening plate 14 is arranged between the support frame 13 and the crushing roller 15. Springs 12 are respectively installed on both sides of the bottom surface of the screening plate 14, and the ends of the springs 12 are connected to the top of the support frame 13. The middle part of the screening plate 14 protrudes upward in an inverted V-shaped structure, and a vibration motor 11 is installed in the middle of the bottom surface of the screening plate 14. The screening plate 14 screens the large-particle material, and the large-particle material is introduced into the return material cavity.

[0023] Further improved, a lifting rod 8 is rotatably connected inside the lifting pipe 5. A spiral blade 10 is welded on the surface of the lifting rod 8. A motor 6 is installed at the upper end of the lifting pipe 5, and the power output end of the motor 6 is connected to the upper end of the lifting rod 8. A return material port is opened at the lower end of the outer wall of the lifting pipe 5. After the motor 6 rotates, it drives the lifting rod 8 and the spiral blade 10. During the rotation of the spiral blade 10, the material at the lower end of the lifting pipe 5 is driven to move upward, and after moving upward, it enters the feed pipe 4 through the return material pipe 7.

[0026] Working principle: The material is put into the machine shell 1 through the feed pipe 4 and crushed by the crushing roller 15. The crushed material falls onto the screening plate 14. The vibrating motor 11 drives the screening plate 14 to vibrate, and the qualified material is discharged downward. The unqualified (larger particles) material is guided to both sides and enters the return material chamber. The material entering the return material chamber is lifted upward through the lifting pipe 5 and returns to the feed pipe 4 through the return pipe 7 after being lifted to a high place, and then is crushed again next time. When it is necessary to adjust the crushing roller 15, rotate the adjusting disc 2 to drive the screw 17 to rotate. After the screw 17 rotates, it drives the adjusting block 18 to move horizontally. The two groups of adjusting blocks 18 move towards the middle or both sides simultaneously, adjusting the distance between the two crushing rollers 15.
