Description

Technical Field

[0001] The invention relates to the technical field of soft ferrite crushing and screening, in particular to a soft ferrite crushing and screening device. Background Art

[0002] Soft ferrite is produced by powder metallurgy. It is mainly a "functional ceramic material" made by sintering iron oxide and other metal oxides together. It has good magnetic conductivity. Compared with general metals, it has weaker coercive force and small residual magnetism after the external current is removed. As an important basic functional material, it is widely used in electronic industries such as communications and transformers. Magnetic powder is an important raw material for soft ferrite. In the process of making soft ferrite, the magnetic powder needs to be crushed first, so a crusher is needed to achieve sufficient crushing of the magnetic powder.

[0003] The existing crusher crushes the magnetic powder by squeezing the magnetic powder block with two sets of crushing rollers turning in opposite directions, which is similar to the patent scheme recorded in the application number "CN202223539086.4". The scheme in the text adds a rolling roller to further grind the magnetic powder. Although the qualified rate of the magnetic powder product is improved, unqualified fragments still fall into the filter cartridge, requiring repeated manual operations, which is more troublesome. Another example is the rolling cylinder recorded in the published patent technology scheme with application number CN202410598896.1, which rolls the magnetic blocks and can be screened repeatedly, but this method can only screen out powder with a specific sieve size and cannot be adjusted. It cannot be used when larger particles of powder are required. Summary of the invention
