[0031] By adopting the above technical scheme, the ball mill for polishing powder processing with noise reduction function is provided with a damper 1403 and a movable rod 1406.

[0033] By adopting the above technical scheme, a ball mill for processing polishing powder with a noise reduction function is provided with a first cover plate 1601, a slot 1603, a screw 1607 and a nut 1608. When the feed port 9 is blocked, people rotate the first cover plate 1601 to cover the feed port 9, and at the same time, the first cover plate 1601 drives the block 1602 and the slot 1603 to approach the position of the screw 1607. People rotate the sleeve 1606 to make the screw 1607 enter the slot 1603, and then rotate the nut 1608. With the cooperation of the nut 1608 and the screw 1607, the nut 1608 approaches and presses the block 1602, thereby firmly fixing the first cover plate 1601 to the feed port 9, making it convenient for people to block the feed port 9.

[0034] Specifically, an annular groove 17 is formed on the surface of the cylindrical liner 10 , and a sound insulation sponge 18 is sleeved on the inner wall of the annular groove 17 .

[0035] Specifically, a gap 19 is opened on the surface of the cylinder 5, and a discharge pipe 20 is passed through the gap 19. One end of the discharge pipe 20 is passed through the inner wall of the annular groove 17, and the other end of the discharge pipe 20 is movably connected to the second cover plate 21 through a hinge.

[0036] Specifically, the cylindrical liner 10 is made of metal, and a plurality of long grooves arranged in a ring shape are formed on its inner wall.

[0037] Specifically, the cross-sectional diameters of the first limiting block 1404 and the second limiting block 1407 are both larger than the diameter of the through hole 1405 .

[0038] Specifically, the inner diameter of the nut 1608 is smaller than the width of the slot 1603 , and the outer diameter of the nut 1608 is larger than the width of the slot 1603 .

[0039] The working principle of the utility model is as follows: when in use, people first add an appropriate amount of raw materials to be processed and iron balls into the cylindrical lining 10 of the cylinder 5 through the feed port 9, and then close the feed port 9 to block the feed port 9. When blocking the feed port 9, people rotate the first cover plate 1601 to cover the feed port 9, and at the same time, the first cover plate 1601 drives the block 1602 and the slot 1603 to approach the position of the screw 1607, and people rotate the sleeve 1606 to make the screw 1607 enter the card slot. The first cover plate 1601 is fixed to the feed inlet 9, which is convenient for people to block the feed inlet 9, and then start to process the raw materials. When processing, people first operate the motor 12, and the motor 12 drives the gear 13 to rotate. Under the mutual cooperation of the gear 13 and the gear ring 11, the gear ring 11 drives the gear 13 to rotate. The movable cylinder 5 and the cylindrical liner 10 rotate. Since the inner wall of the cylindrical liner 10 is provided with long grooves, the long grooves will drive the iron balls staying in the corresponding long grooves to rotate and rise a certain distance when following the rotation of the cylindrical liner 10. When the centrifugal force of the iron balls is less than its own gravity, the iron balls fall to hit the raw materials to be processed, and the iron balls will continue to rise and fall, so that the raw materials to be processed are continuously hit and broken until the raw materials to be processed reach the expected effect. In this process, since the iron balls inside the ball mill continue to rise and fall, the cylindrical liner 10 and the cylinder 5 will be continuously impacted to generate a large noise. The impact force is transmitted to the damping 1403 through the buffer plate 1 and the movable rod 1406. The damping 1403 can absorb most of the impact force, thereby reducing the impact force and the noise generated by the impact, which is convenient for people to reduce the noise generated during the production process of the ball mill. In addition, sound insulation cotton 18 is provided in the annular groove 17 of the cylindrical liner 10. The sound insulation cotton 18 can have a certain sound insulation effect and can further reduce the noise generated during the production process.

After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
