[0026] Specific implementation principle: When using the utility model, first pour the powder coating into the left side of the feed hopper 1, part of the powder coating can pass through the preliminary filter 102 to reach the second grinding layer 4, and the powder coating that does not pass through the right side falls into the first grinding layer 3, and the powder coating that falls into the middle is rotated and initially ground by the first main grinding rod 301 and the second main grinding rod 307 controlled by the first motor component 302, and the powder coating that falls on both sides is rotated and ground by the first main grinding rod 301 and the first auxiliary grinding rod 306 or the second main grinding rod 307 and the second auxiliary grinding rod 305 controlled by the first motor component 302, and the ground powder coating enters the second grinding layer 4 , the second grinding rod 402 inside the second grinding layer 4 is controlled by the second driving structure 405 controlled by the second motor 401 to roll back and forth and grind until the size of the powder coating can pass through the second filter layer 403, and the powder coating enters the third grinding layer 5, and the third grinding rod 505 driven by the third driving structure 506 controlled by the third motor 504 rolls left and right and grinds. The weight of the third grinding rod 505 is greater than the weight of the second grinding rod 402. Because the volume of the powder coating entering the third grinding layer 5 is smaller, it may have the effect of dusting. Too small dust is sucked away by the dust collecting box 7 of the fan 701 through the dust filter 501 to prevent the dust from being exposed to the air. The ground powder coating passes through the third filter layer 502 and reaches the receiving box 6. After using for a period of time, if the grinding speed is found to be slow, the first filter layer handle 304, the second filter layer handle 404 and the third filter layer handle 503 can be pulled to replace or clean the filter.
