The vibrating screen not only has a screening function, but also has the function of magnetically removing iron-containing particles, which effectively reduces the footprint of the equipment.

[0022] The vibration frame 100 in this embodiment is used to connect the first vibration screen 200 and the second vibration screen 400 to provide support for the vibration of the first vibration screen 200 and the second vibration screen 400.

A second discharge end 430 is formed at the bottom of the second screen frame 410 for collecting and discharging non-magnetic granular materials. A third discharge end 440 is provided at the bottom of the second screen 420 for collecting and discharging powder materials. A third discharge end 440 is provided at the top of the second screen frame 410 for receiving the magnetic material released by the electromagnet 320 above it.

[0028] The magnetic separation assembly 300 in this embodiment is used to separate magnetic plastic particles from non-magnetic plastic particles. The magnetic separation assembly 300 includes a conveyor belt 310 and a plurality of electromagnets 320. The conveyor belt 310 is disposed below the first vibrating screen 200 and spaced apart from the vibrating frame 100 to receive the undersize material from the first vibrating screen 200. The plurality of electromagnets 320 are sequentially arranged along the circumference of the conveyor belt 310. The electromagnets 320 can be moved above the conveyor belt 310 and energized to absorb magnetic material.

[0036] Compared with the prior art: the material is introduced into the top of the first vibrating screen 200. As the first vibrating screen 200 vibrates, the material that meets the specifications can be screened out, and the special-shaped material is intercepted on the first vibrating screen 200.
