[0038] Working principle: Before using a powder pulverizing device that can avoid dust generation, it is necessary to first check the overall condition of the device to ensure that it can operate normally. According to Figure 1 - Figure 5 As shown, first pour the powder into the feeding hopper 103, start the first driving motor 104 to drive the feeding paddle 105 to rotate. By using the cooperation between the feeding paddle 105 and the feeding auger 102, the powder can be slowly transported to the grinding disc 108. Start the second driving motor 107 to drive the grinding disc 109 to rotate. By using the cooperation between the grinding disc 108 and the grinding wheel 111, the powder can be ground. At the same time, start the blower 117, which can not only dry the powder, but also transport the powder at the bottom of the pulverizing chamber 101 to the vicinity of the separator 113. The powder is screened by the separator 113, and the qualified powder falls into the collection box 116 through the collection pipe 114 for collection;

[0039] Secondly, start the exhaust fan 207 to suck the dust near the dust suction hood 203 into the dust removal box 201. By using the filtering function of the filter cartridge 204, the dust in the air can be excluded, and the dust falls into the storage box 206, thereby collecting the dust. When it is necessary to clean the filter cartridge 204, start the second pulse air pump 205, and the pulse formed by compressing air can clean the filter cartridge 204 to avoid blockage of the filter cartridge 204.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
