Through research and analysis, it is found that although the grinding device has the advantages of being able to adapt to different grinding requirements and accelerating the screening efficiency of materials, it still has the following disadvantages to a certain extent;

Some of the rubber powder ground on the grinding equipment will be retained on the grinding device and cannot be discharged smoothly, which will also interfere with the subsequent grinding effect and is not conducive to the continuation of the grinding work. In order to solve the above technical problems, we have designed a graphene processing grinding equipment that can perform screening simultaneously to solve the above problems. It is necessary.

One end of the air pump 13 is connected to a connecting pipe 14. By setting the connecting pipe 14, the air pump 13 is indirectly connected to the annular pipe 15, which facilitates the smooth transportation of gas. The two ends of the connecting pipe 14 respectively penetrate the inner cavity of the receiving box 4 and are connected to the annular pipe 15. The annular pipe 15 is movably connected to the surface of the grinding disc 7, and the annular pipe 15 is connected to the inner cavity of the grinding disc 7.

[0023] See also Figure 3 A bearing is movably connected between the rotating shaft of the driving motor 5 and the inner wall of the receiving box 4. One side of the bearing is fixedly connected to the inner wall of the receiving box 4. The bearing is movably sleeved on the surface of the rotating shaft of the driving motor 5. By setting the bearing, the rotating shaft of the driving motor 5 and the inner wall of the receiving box 4 can be stably connected, which facilitates the rotation of the rotating shaft of the driving motor 5.

[0024] See also Figure 3 The surfaces of the workbench 2 and the annular tube 15 are provided with matching positioning grooves 16. By setting the positioning grooves 16, the workbench 2 and the grinding disc 7 can maintain relative positions when they are not moved by force, which can improve the stability and accuracy of the guide rod 20. A support plate 17 is welded to the inner wall of the shell 1, and the top of the support plate 17 is in contact with the bottom of the sieve plate 10. By setting the support plate 17, the sieve plate 10 can be laterally supported so that it can be stably placed in the inner cavity of the shell 1.

[0025] See also Figure 5 The adjusting mechanism 8 includes a hydraulic rod 18, which is arranged through the top of the grinding disc 7. The bottom of the hydraulic rod 18 is fixedly connected to a support plate 19.

The friction between the grinding disc 7 and the particles grinds the block-like rubber powder into powder. The air pump 13 is controlled to operate by the external controller to extract the external gas and transport it to the inside of the annular tube 15 through the connecting pipe 14 to the grinding disc 7. The accelerated airflow is filled inside, and the ground powder can be blown away from the through hole 12 to avoid powder accumulation affecting the subsequent grinding effect. According to the law of heat conduction, the contact area with the air can be increased to take away the heat on the surface of the grinding disc 7 to achieve a better cooling effect. The blown-away ground rubber powder is sieved through the sieve holes of the sieve plate 10 and then discharged for refining, and then falls into the collecting box 11 to be collected. The excess air in the workbench 2 can also be discharged from the shell 1 through the sieve holes, while the ground powder is left in the collecting box 11. The hydraulic rod 18 is started by the external controller to extend and retract to drive the support plate 19 and the guide rod 20 to move vertically respectively, and can contact the sieve holes of the sieve plate 10 through the guide rod 20, and exert a load thrust on the remaining particles blocked in the sieve holes, so that the particles are detached for subsequent screening and use, which is more practical.
