[0023] The outer wall fixed sleeve of the discharge pipe 3 is provided with a circular screen 4, and the outer wall of the circular screen 4 is evenly provided with multiple fine screen holes 6 and coarse screen holes 5. The circular screen 4 is divided into left and right parts, the right side is multiple fine screen holes 6, and the left side is coarse screen holes 5. The outer wall sliding sleeve of the discharge pipe 3 is provided with a circular cover 7, and the bottom of the circular cover 7 is fixedly connected to four tripods 8.

[0024] Four guide plates 9 are fixedly connected to the inside of the circular cover 7. The four guide plates 9 are located on the top of two discharge pipes 11 in groups of two, and play the role of guiding materials. An arc plate 10 is fixedly connected to the inside of the circular cover 7. The top of the arc plate 10 is slidingly connected to the outer wall of the circular screen 4. Two discharge pipes 11 are fixedly connected to the bottom of the circular cover 7. The two discharge pipes 11 discharge different screened materials, and the existing belt conveyor is used for discharge.

[0025] A cleaning mechanism is provided inside the circular cover 7, which includes an assembly plate 14. The top of the circular cover 7 is fixedly connected to two fixed blocks 12. The outer walls of the two fixed blocks 12 are provided with sliding holes. The inner walls of the two sliding holes are slidably connected with the same threaded rod 13. The outer wall thread sleeve of the threaded rod 13 is provided with a nut, which is squeezed between the nut and one of the fixed blocks 12. The nut fixes the threaded rod 13 on the fixed block 12.

[0026] Working principle: When in use, the ball mill body 1 rotates and grinds the powder material with the grinding medium inside. The discharge pipe 3 rotates along with the rotation of the ball mill body 1. The rotation of the discharge pipe 3 drives the multiple spiral conveying blades 17 to rotate, and the material in the ball mill body 1 is spirally conveyed out. The spacing between the spiral conveying blades 17 is smaller than the grinding medium, which blocks it and prevents it from being discharged with the material. The material in the discharge pipe 3 is slowly discharged into the circular screen 4. The material first passes through multiple fine sieve holes 6 for initial screening, and the finer material is removed. The material is discharged from the discharge pipe 11 on the right side of the circular screen 4, and the material continues to enter the circular screen 4 and is squeezed and pushed outward. The material is then screened by multiple coarse screen holes 5. The screened material is discharged from the discharge pipe 11 on the left side of the circular screen 4, and the largest particle material is directly discharged through the left opening of the circular screen 4, forming a multi-stage screening. At the same time, as the circular screen 4 rotates, two wire brushes 16 clean its inner and outer surfaces, and brush out the material in the coarse screen holes 5 and the fine screen holes 6 to avoid blockage.
