Description

Technical Field

[0001] The present disclosure relates to the technical field of battery powder production, and in particular to a powder screen vibration device. Background Art

[0002] In the battery recycling process, the ternary positive electrode material needs to be recycled and processed. The processed ternary positive electrode material can be reused in the production of ternary positive electrode materials. When processing the ternary positive electrode material, the positive electrode material needs to be sintered, and then the powder of the positive electrode material needs to be sieved after sintering. Only the powder of the positive electrode material that meets the certain particle size requirements after sieving can be used in the production of ternary positive electrode materials.

[0003] During the screening process, a sieve with a mesh size between 300 and 500 is required to screen the particle size of the positive electrode material powder.

Since each layer of the sieve of the battery powder screening equipment is connected by a clamp type, each layer of the sieve needs to be disassembled during the cleaning process, which requires a lot of time and labor, affecting the efficiency of the battery powder screening equipment in screening powder.
