Problems solved by technology

[0002] In the process of decomposing and producing carbonyls such as nickel carbonyl and iron carbonyl, metal powder products with low bulk ratio are prone to blockage between the intermediate bin and the material bin, and it is necessary to repeatedly knock the bin body and use the material bin to inflate and pressurize the powder. Blowing or increasing the feeding screw to rotate the feeding, etc., but these methods will inevitably have certain safety hazards or have a greater impact on the stable production of the system and the stability of product quality.
At the same time, due to the large difference in the performance of the fine particles collected by the dust collector and the production powder, the stability of the product quality of the production powder will be affected when the same material bin is used for receiving and processing
