In order to obtain nanometer material, it is usually necessary to finely process raw materials by mechanical, chemical or physical methods. Among them, mechanical ball milling is a commonly used technology for preparing nanometer material. Through ball milling, raw materials can be broken, refined, mixed and reacted under the action of mechanical force, so as to obtain nanometer powder or crystal grain.

[0003] According to the search, the patent number CN220328851U is a kind of nanometer material raw material ball mill device, including base, the base upper surface is fixedly installed with a plurality of support rollers, the support roller between activity is equipped with roller, the roller one end is equipped with feeding assembly, the feeding assembly one side is fixedly connected with dust removal assembly, the dust removal assembly includes annular pipe, dust removal frame, tee bend, fan and air inlet pipe, the roller other end is equipped with collection assembly, the collection assembly includes cover body, filter screen, second sealing element, screw ring, bolt and discharge pipe. In the utility model, the dust removal device can be driven by independent motor to remove dust, so as to prevent dust leakage caused by low suction force at the feeding port. At the same time, it is convenient to directly discharge the powder floating outward into the roller, replacing manual cleaning of powder. Moreover, it is convenient to screen out the nanometer material that has been ground when the roller rotates, improving the grinding efficiency.

[0004] Based on the above patent, by pouring nanometer raw materials into the feeding bin, along the inclined plate into the roller interior, the first sealing element seals between the roller and the feeding bin, and the roller can rotate freely. The fan operates to generate suction at the dust removal frame, and the floating dust is collected into the annular pipe. Then, through the tee bend, the air is gathered and discharged into the roller through the air inlet pipe. At the same time, the air pumped by the air inlet pipe blows the nanometer raw materials to the surface of the filter screen. The air passes through the filter screen and the collection box, and finally is discharged from the air-permeable filter plate. Thus, the dust removal device can be driven by independent motor to remove dust, so as to prevent dust leakage caused by low suction force at the feeding port. At the same time, it is convenient to directly discharge the powder floating outward into the roller, replacing manual cleaning of powder. However, in the process of making the ball mill and nanometer raw materials break, refine, mix and react under the action of mechanical force, the low speed generated during the use of the device leads to low grinding efficiency, and high speed causes centrifugal effect, making the grinding balls adhere to the tank wall, reducing the collision effect, and making it inconvenient to fully mix the ball mill and raw materials, thereby affecting the grinding efficiency of the device on the raw materials.
