The ultrafine aluminum powder production system comprises an aluminum-water cyclone atomizing cooling device, and the aluminum-water cyclone atomizing cooling device comprises an aluminum-water atomizing device, a cyclone generator and a cooling tank which is connected to the bottom of the cyclone generator and used for cooling the aluminum mist to aluminum powder; the ultrafine aluminum powder production system also comprises a plurality of levels of aluminum powder grading devices, wherein a powder outlet of a previous level of aluminum powder grading device is connected with a powder inlet of the following level of aluminum powder grading device; the powder inlet of a first level of aluminum powder grading device is connected with a powder outlet of the cooling tank; the power outlet of a last level of aluminum powder grading device is connected with an air inlet of a cyclone dust collector, and the cyclone dust collector is suitable for filtering residual aluminum powder from nitrogen; each aluminum powder grading device is identical in structure and comprises a centrifugal grader, a buffer tank which is suitable for collecting the coarse powder separated from the previous level of the aluminum powder grading device and a transmitting tank which suitable for conveying the coarse powder in the buffer tank to an aluminum powder packaging unit.

Description

Technical field [0001] The invention relates to a production method of aluminum powder. Background technique [0002] In the prior art, the production process of aluminum powder is inseparable from a grading system. The grading system classifies aluminum powder of different diameters according to production needs. The traditional classifier has less strict control of aluminum powder grading particles and is easy When the ultrafine aluminum powder is mixed with aluminum powder of different diameters, the grading effect is often not enough to meet the production needs. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a production method of aluminum powder, which solves the technical problem of wide particle size distribution in the classification of aluminum powder. [0004] In order to solve the above technical problems, the present invention provides a production method of aluminum powder, including: an ultra-fine aluminum ...
