Problems solved by technology

The technical solution disclosed in the present invention cannot completely exclude some of the larger magnetic powder particles from being discharged from the winnowing mechanism. At the same time, only through the impact of the crushing hammer on the flywheel and the magnetic powder particles, the impact between the mechanical magnetic powder particles can achieve crushing, and the crushing efficiency is relatively high. Low

Description

technical field [0001] The invention relates to the field of preparation of magnetic powder particles, in particular to a preparation device for magnetic powder particles with high crushing efficiency and uniform particle size of the prepared magnetic powder. Background technique [0002] Uniform particle size of magnetic powder is a prerequisite for obtaining good magnetic powder materials, but the actual situation is that the obtained particles are normally distributed, that is, D90, D50, and D10, which conform to the normal distribution curve. The powder in the ideal state is all D50 and uniform in size, but this is difficult to achieve. The powder prepared in the prior art has poor uniformity, resulting in uneven magnetic properties. [0003] CN102110507A discloses a superfine NdFeB magnetic powder, which is composed of an automatic feeder, a grinding chamber, a cyclone separator, a filter, a nitrogen compressor, and a cold dryer. The coarse magnetic powder material en...
