[0026] In the specific implementation process, it is worth pointing out that the staff can open the cover 7, and then discharge the screened materials from the inside of the box 1. When the cover 7 is opened, the first spring 6 is compressed. At this time, the cover 7 can be pushed back to its original position by the elastic force of the first spring 6, so that the box 1 can be opened;

[0027] Specifically, when using the pre-magnetic separation device of the crusher, the staff first pours the material into the interior of the box 1, and then turns on the external power supply of the screening device 2.
