Description

Technical Field

[0001] The utility model relates to the technical field of metal processing equipment, and particularly relates to a screening device for magnesium metal processing. Background Art

[0002] The processing and screening of magnesium metal usually involve several steps to ensure that the purity, shape, and quality of the material meet the requirements, including a powder screening process, which is mainly for particle size classification. A vibrating screen or an air classifier is used to classify magnesium powder according to particle size to meet the requirements of different applications.

[0003] The existing screening devices for magnesium metal processing still have the following problems when in use: The screening main body is a vibrating screen or an air classifier. When the vibrating screen is screening magnesium metal powder, the screening efficiency of the vibrating screen may be affected by factors such as the screen aperture, vibration frequency, and material characteristics. Especially when dealing with fine-grained materials, the effect may not be good, while the initial investment and maintenance costs of the air classifier are relatively high, especially for high-precision classification requirements.
