[0002] Magnetic steel generally refers to aluminum-nickel-cobalt alloy. Magnetic steel is composed of several hard and strong metals, such as iron, aluminum, nickel, cobalt, etc., and sometimes copper, niobium, and tantalum. It is used to make super-hard permanent magnetic alloys. The production of magnetic steel mainly involves stamping metal powder into shape and then heating it. In order to ensure the quality of the product, the metal powder needs to be screened before processing to ensure the quality of the metal powder particles.

[0003] The existing metal powder screening is mainly carried out through a rotary vibrating screen. The processing process is that the staff pours the metal powder onto the screen.
