Description

TECHNICAL FIELD

[0002] In the prior art, there are some significant limitations in the screening device of atomized metal powder. First, these devices can only perform single-layer screening, which cannot achieve multi-layer screening, limiting the screening efficiency and accuracy. Since different particle sizes of powder cannot be screened layer by layer, fine particles and coarse particles are mixed together, affecting the quality and uniformity of the final product. This limitation of single-layer screening not only reduces the screening efficiency, but also increases the waste of powder, which is not conducive to cost control and environmental protection.
