[0002] A Chinese patent with announcement number CN210753125U discloses a crushing device for recycling rare earth waste, including a crusher, one end of the crusher is embedded with an inlet, the inner side of the inlet is installed with a crushing frame, both sides of the crusher are movably connected with extrusion plates, one side of the extrusion plate is installed with an extrusion block, a small motor rotates on one side of the extrusion plate, the outer side of the small motor rotates with a limiting cylinder, an extrusion bearing rotates under the extrusion plate, a filter screen is installed on one side of the crusher, a collection box is penetrated on one side of the filter screen, a stepping motor rotates on one end of the filter screen, a rotating plate rotates on one side of the stepping motor, a screening screen is penetrated inside the rotating plate, a motor is installed on one side of the screening screen, and a motor is installed on one side of the crusher.

[0003] The above-mentioned device is provided with a rotating plate, so that when the extrusion bearing crushes the rare earth waste, the waste enters the interior of the rotating plate, and can drive the screening net through the motor to filter the crushed rare earth waste. The rotating plate is driven to rotate by the stepper motor, and the incompletely filtered rare earth waste can be passed through the filter net into the interior of the collection box for collection by the rotating plate, so that the crushing device can filter the rare earth and collect the incompletely crushed rare earth waste.
