For the support leg 27 installed outside the discharge outlet 26, the support leg 27 can support the sand mill main body 1, thereby facilitating the use of the device.

[0030] Working principle: During operation, when installing the filter sieve plate 9, a spring 6 can be installed in the convex groove 5 opened inside the mounting plate 4. The spring 6 can push the push plate 7 and the push block 8 to move inside the convex groove 5. When the push block 8 moves out of the mounting plate 4, the top of the push block 8 can install the filter sieve plate 9; when disassembling the filter sieve plate 9, it is necessary to manually press the push block 8. So that when the push block 8 is pressed, the push plate 7 can squeeze the spring 6, so that the push block 8 can be pressed into the convex groove 5. When the push block 8 is pressed into the convex groove 5, it is convenient to take out the filter sieve plate 9 from the bottom of the mounting plate 4;

[0031] Since the mounting block 2 is welded to the outside of the sand mill body 1, the mounting groove 3 opened on the front of the mounting block 2 can be inserted with the mounting plate 4. So that when the mounting plate 4 is inside the sand mill body 1, the filter sieve plate 9 can screen the material. When it is necessary to quickly screen the material, a first driving motor 11 is installed in the machine groove 10 opened inside the mounting plate 4. The output shaft of the first driving motor 11 can drive the first rotating rod 12 to rotate. The sealing block 13 installed inside the machine groove 10 can seal the machine groove 10, thereby preventing the material from entering the inside of the machine groove 10; the fixing block 14 installed on the mounting plate 4 enables the first rotating rod 12 to be rotatably connected inside the mounting bin 15 welded to the bottom of the fixing block 14. When the first rotating rod 12 rotates, it can drive the second bevel gear 17 meshing with the outer wall of the first bevel gear 16 to rotate. The rotating second bevel gear 17 drives the second rotating rod 18 to rotate inside the mounting bin 15. The brush plate 19 is welded to the outside of the second rotating rod 18. So that when the brush plate 19 rotates, it can quickly screen the material on the top of the filter sieve plate 9; the second driving motor 22 welded to the top of the sand mill body 1 drives the third rotating rod 23 to rotate. The rotating third rotating rod 23 can drive the dispersion shaft 24 to stir the material. At the same time, the feed port 25 opened on the top of the sand mill body 1 is convenient for adding the material. After the material is screened, it is discharged through the discharge port 26. The support legs 27 are installed to enable the support legs 27 to support the sand mill body 1, thereby facilitating the use of the device.
