[0031] In the initial state, the cylinder 2 is filled with a proper amount of grinding media; when the quartz sand needs to be ball-milled, firstly, a proper amount of quartz sand needs to be put into the cylinder 2 through the left end of the feed pipe 4, and then the driving motor 11 drives the driving gear 13 to rotate, the driving gear 13 can drive the driven gear ring 14 to rotate, and the driven gear ring 14 can drive the cylinder 2 to rotate clockwise (it should be emphasized that the side plate 3 does not rotate with the cylinder 2), and the cylinder 2 can drive the grinding media and quartz sand therein to rotate clockwise, and the grinding media and quartz sand in the cylinder 2 will rotate clockwise. The quartz sand is crushed and refined by the collision and friction between the two liner plates 5. Since the grinding medium only rotates and freely falls in the front half of the cylinder 2, it will not affect the mounting plate 6 and the components thereon. The quartz sand with a particle size smaller than the gap between the two liner plates 5 will fall into the groove 501 of the liner plate 5. The rotation of the liner plate 5 can drive the quartz sand in the groove 501 to rotate to the inner upper part of the cylinder 2, and the groove 501 on the inner upper part of the cylinder 2 will be in an inclined state, so that the quartz sand in the groove 501 on the inner upper part of the cylinder 2 can be crushed and refined by the collision and friction between the two liner plates 5. The quartz sand that does not meet the screening criteria will slide forward onto the fixed inclined plate 23, and fall down along the fixed inclined plate 23 to the lower side of the cylinder 2 for re-ball milling. The quartz sand that meets the screening criteria will fall down into the upper guide frame 22, and fall down along the inner wall of the upper guide frame 22 to the middle guide frame 22. Secondary screening is performed on the ultrasonic vibrating screen 21, so that the quartz sand can be screened three times by three ultrasonic vibrating screens 21, and the quartz sand after three screenings will enter the three second screw conveyors 26 respectively, and the quartz sand can be transported to the discharge pipe 27 through the second screw conveyor 26, and the discharge pipe 27 can discharge the quartz sand out of the cylinder 2, and be collected manually, so that the ball-milled quartz sand in the cylinder 2 can be discharged and classified in time, thereby preventing the quartz sand from being over-crushed and improving the processing efficiency of the entire ball milling device;When it is necessary to adjust the grinding degree of quartz sand, first, the winch 9 can be controlled to loosen the wire rope on it, so that the rotating inclined plate 7 can rotate forward and open under the action of gravity, and the rotating inclined plate 7 can pull the front end of the connecting cloth 8 to move forward, so that the connecting cloth 8 is unfolded. At this time, the right end of the connecting cloth 8 is located on the left side of the fixed ring 15, and then the lifting baffle 17 is driven to rise by the hydraulic cylinder 19, which can drive the discharge pipe 18 to rise until it is aligned with the fixed ring 15. At this time, the driving motor 11 is controlled to continue to drive the cylinder 2 to rotate, and the cylinder 2 can drive the grinding medium inside it to rotate clockwise. When the grinding medium rotates to the top of the cylinder 2, it will perform free fall and fall onto the connecting cloth 8, and roll to the right along the connecting cloth 8 to pass through the fixed ring 15 and the discharge pipe 18 in turn. Discharged outside the cylinder 2, then other sizes of grinding media can be put into the cylinder 2 through the feed port at the upper end of the feed pipe 4, so that the purpose of adjusting the grinding degree can be achieved by replacing grinding media of different sizes, and the grinding media can be quickly replaced to improve the ball milling efficiency; according to the adjusted grinding degree value, the electric push rod 29 can be controlled to drive the second screen plate 28 to move left and right, so that the sieve holes on the second screen plate 28 can be staggered with the sieve holes on the first screen plate 2101, so that the particle size of each ultrasonic vibration screen 21 can be adjusted to adapt to the adjusted grinding degree value. When the sieve holes on the second screen plate 28 are completely aligned with the sieve holes on the first screen plate 2101, the particle size screened by the ultrasonic vibration screen 21 is the largest. ;

[0032] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
