Crushing soft magnetic alloy powders is crucial. Mechanical crushing, ball milling, air flow crushing and other methods can be used. Each has its own characteristics and scope of application. The crushing process needs to consider factors such as efficiency, quality and cost, while preventing oxidation, contamination and agglomeration.

[0003] The patent application with application number CN202022014130.4 discloses a crushing device for soft magnetic alloy powder, including: a hopper, a vibrating feeder fixedly arranged at the bottom of the hopper, a positive spiral feeding device fixedly installed at the discharge end of the vibrating feeder, a grinder fixedly installed at the other end of the positive spiral feeding device, a reverse spiral discharging device fixedly installed at the other end of the grinder, a multi-stage dust collector connected to the other end of the discharging device, and a nitrogen drainage pipe arranged at the feed port of the grinder, the other end of the reverse spiral discharging device is connected to the first exhaust fan, and the air outlet end of the multi-stage dust collector is connected to the nitrogen circulation pipeline through a dust filtering device.
