The output end of the servo motor 2 is fixed with a vertical shaft 8 through a coupling, and three groups of grinding disc groups 13 are provided on the outer surface of the vertical shaft 8. The grinding disc groups 13 all include a mother disc 1301 sleeved on the outer surface of the vertical shaft 8, and a number of guide protrusions 1302 are movably connected to the side wall of the mother disc 1301 for grinding. A number of movable grooves 1303 are provided on the side wall of the mother disc 1301 for the guide protrusion 1302 to be engaged, and the internal dimensions of the movable grooves 1303 are adapted to the ends of the guide protrusions 1302, thereby improving the guide protrusions. The stability of the block 1302 movement, the inner wall of the movable groove 1303 is fixed with a contraction spring 1304, the other end of the contraction spring 1304 is fixed to the end of the guide protrusion 1302, which is convenient for the guide protrusion 1302 to reset, and a number of grinding blocks 14 are evenly spaced on the side wall of the grinding machine case 1 just above the isolation plate 11 to increase the friction resistance. The isolation plate 11 is flush with the bottom end of the master disc 1301 to support the master disc 1301. The isolation plate 11 is arranged on the outer surface of the vertical shaft 8 through a mechanical sealing sleeve, and the sleeve 1002 is arranged on the outer surface of the vertical shaft 8 through a mechanical sealing sleeve, which improves the stability of the rotation of the vertical shaft 8. The servo motor 2 is started to drive the vertical shaft 8 to rotate, thereby driving the master disc 1301 and the guide protrusion 1302 to rotate. The kaolin is ground between the grinding block 14, the mother disc 1301 and the guide protrusion 1302. During grinding, the mother disc 1301 rotates to generate centrifugal force to suspend the powder particles, so that they are fully ground. The ground particles fall to the surface of the isolation plate 11 under the action of gravity, and then driven by the mother disc 1301, the particles are preliminarily screened from the screen 2 12 and fall to the surface of the screen 1001.

The surface of the slide plate 9 is parallel to the screen 1001. The surface of the bottom end of the slide plate 9 is parallel to the inner bottom of the discharge port 3, which improves the convenience of powder discharge.

The two ends of the pneumatic conveying pump 5 are connected with the discharge port 2 4 and the feed port 1 6 in turn through pipes. Starting the pneumatic conveying pump 5 can generate wind force to transport the large particles of kaolin inside the discharge port 2 4 to the inside of the feed port 1 6 and then into the interior of the grinding machine box 1, thereby realizing cyclic grinding.

[0025] Working principle: When using this kaolin grinding device, the operator first connects an external power supply, pours the kaolin to be ground from the feed port 2 7 into the interior of the grinding machine box 1, starts the servo motor 2 to drive the vertical shaft 8 to rotate, thereby driving the mother disc 1301 and the guide protrusion 1302 to rotate, so that the kaolin is ground between the grinding block 14 and the mother disc 1301 and the guide protrusion 1302. During grinding, the rotation of the mother disc 1301 generates centrifugal force to suspend the powder particles, thereby fully grinding them. The ground particles fall to the surface of the isolation plate 11 under the action of gravity, and fall to the surface of the screen 1001 after screening from the screen 2 12 under the drive of the mother disc 1301. The vibration motor 1003 is started to drive the screen 1001 to vibrate, so that the ground particles vibrate and slide down on the surface of the screen 1001, thereby realizing screening. The qualified particles fall to the surface of the slide 9 and are discharged from the discharge port 3 to complete collection, and the large particles are discharged through the discharge port 2 4, thereby improving the quality of the kaolin particles discharged from the grinding.

[0026] Secondly, by starting the pneumatic conveying pump 5, wind power can be generated to transport the large particles of kaolin inside the discharge port 2 4 to the inside of the feed port 1 6 and then into the inside of the grinding machine box 1, thereby facilitating the grinding cycle and improving the grinding quality.
