[0033] In summary, if Figure 1-Figure 8As shown, the pulverized coal mill for processing ceramic tiles with high uniformity, when in use, can drive the driving gear 803 to rotate through the design of the motor 801 and the connecting shaft 802, and the driving gear 803 is meshed with the auxiliary gear 804, and the two ends of the grinding mill 1 are respectively connected to the feed port 2 and the transfer feed frame 3 through the design of bearings, so that the driving gear 803 and the grinding mill 1 connected to the driving gear 803 can rotate synchronously, and then the ceramic tile raw materials fed into the grinding mill 1 through the feed port 2 can be ground by the rotation of the grinding balls, and then the ceramic tile raw materials after the preliminary grinding are passed through the grinding mill 1 The unloading area on one side enters the transfer feeding frame 3 (the working principle and unloading of the pulverizer are the existing technology. The crushed coal blocks are input into the cylinder from the feeding mechanism (that is, the coal blocks are input into the pulverizer 1 from the feeding port 2 in this article). When the cylinder rotates, the steel balls, i.e. the grinding bodies, are attached to the lining plate in the cylinder due to the inertia and centrifugal force and the friction force, so that the steel balls can be carried away by the cylinder by the cylinder. When they are brought to a certain height, they are thrown down due to their own gravity. The falling grinding bodies crush the coal blocks in the cylinder. Now, improvements and innovations are made on this basis, and the reference application number is CN202321869727.4. The grinding mill 1 can unload materials by itself after the centrifugal grinding with grinding balls is completed). The filter screen 25 arranged inside the transfer feeding frame 3 can be used to screen the tile raw materials after the preliminary grinding is completed, so as to ensure that the grinding mill grinds the tile raw materials evenly. When the grinding mill 1 rotates, the first connecting column 10, the second connecting column 11 and the ball seat 12 connected thereto will rotate along with it. When the first connecting column 10, the second connecting column 11 and the ball seat 12 rotate, they will fit on the outer surface of the roller 23 and rotate. The diameter of the first connecting column 10 and the diameter of the combination of the second connecting column 11 and the ball seat 12 are different, so that the transfer feeding frame 3 connected to the roller 23 can be continuously rotated when the grinding mill 1 rotates. The column 22 and the adjustment component 19 move up and down in the built-in groove 24 inside the transfer feeding frame 3, so as to drive the filter screen 25 connected to the connecting block 1901 to vibrate up and down in the transfer feeding frame 3, which is beneficial to the screening of the tile raw materials after the initial grinding on the outer surface of the filter screen 25. The powder particles with uniformity will be transferred to the grinder 24 through the filter screen 25, which is beneficial to use the grinder 24 to grind the tile raw materials again, and further improve the uniformity between the grinding materials of the tile raw materials. In addition, the grinder 24 can be rotated by the driving component 8, and when the grinder 24 rotates, the side plate 1501 and the teeth 1502 can rotate synchronously. The design of the number and position distribution of the teeth 1502 with respect to the side disc 1501 enables the side disc 1501 to intermittently mesh with the transverse gear 1504 on the outer surface of the cross column 1503 through the teeth 1502, so that the transverse gear 1504, the cross column 1503, the built-in plate 27 and the scraper 18 will rotate in the upper area inside the transfer feed frame 3, and the tile powder that cannot be sieved can be intermittently pushed to the side baffle plate 26 area, and the side baffle plate 26 is engaged with the transfer feed frame 3, so that the raw materials that cannot be sieved can be taken out and re-grinded by the grinder 1. Secondly, the design of the motor 801 and the connecting shaft 802 can drive the active gear 803 to rotate, and the active gear 803 meshes with the auxiliary gear 804, so that the driving gear 803 and the grinding mill 1 connected to the driving gear 803 will rotate synchronously, and then the external gear 9 in the middle of the outer surface of the grinding mill 1 will follow the movement. The rotation of the external gear 9 can drive the transmission gear 1703 meshed with it to rotate around the extension shaft 1702, and the auxiliary shaft 1704 and the fan blade 1705 connected to the transmission gear 1703 will rotate with the rotation of the transmission gear 1703. Through the above operation, the air flow rate around the motor 801 can be increased to assist the heat dissipation of the motor 801. In addition, the heat dissipation of the motor 801 is started with the operation of the motor 801, which has a following effect. .
