In some embodiments, the non-magnetic material in the battery material may include a powdered material or a bulk material. Such as copper, aluminum, lithium-containing powdered materials, are not affected by the magnetic field. The rotary vibrating screen is driven by a rotary vibrating motor 701 and can be used for sorting powdery battery materials and sheet battery materials. After the nonmagnetic battery material falls into the suspension vibration sieve, the powder-shaped positive battery material can pass through the screen mesh and enter the discharging pipe 702 and then enter the corresponding positive material collecting box through the rotary vibration sieve for separation. The structure of the rotary vibrating screen is not limited in the invention, and a person skilled in the art can use the rotary vibrating screen device in the prior art. The gravity separator 703 is used to separate the sheet battery material. After screening by the suspension vibration sieve, flaky copper and aluminum materials enter a gravity separation device 703 and respectively enter corresponding material collection boxes after separation.

Specifically, the double-layer rotary vibration screen comprises a first rotary vibration layer and a second rotary vibration layer. The discharge gate and the positive electrode material collecting box intercommunication of layer are vibrated soon to first, and the discharge gate and the gravity separation device intercommunication of layer are vibrated soon to the second for select separately powdered battery material and slice battery material. The gravity separation device can be respectively communicated with a plurality of corresponding material collecting boxes and is used for further separating the sheet battery materials.
According to the scheme of the invention, through the negative pressure exhaust pipeline at the top of the material collecting box, negative pressure can be formed in the pipeline, so that gas in the device flows in a guiding way, powder and harmful gas generated in the whole recovery device are recovered, the formed negative pressure can also enable the whole device to be arranged in a sealing way, and the harm of gas leakage to staff is reduced. Meanwhile, the formed negative pressure can also promote blanking efficiency in the crushing and sorting processes, and reduce accumulation conditions of battery materials at all parts, so that damage to equipment is reduced.
