Description

Technical Field

[0001] The utility model relates to the field of lithium battery material processing, in particular to a novel lithium battery material vibrating screen machine. Background Art

[0002] Vibrating screen machine is a main machine for producing battery materials. The parts in contact with battery materials are made of 304 stainless steel. During the vibration screening process of battery materials, metal debris will be produced on the surface of the parts due to wear. The debris will be mixed into the battery material and cause the battery to heat up or short-circuit. Therefore, Teflon coating is usually set on the surface of the parts in contact with the battery material. Although the Teflon coating can separate the battery material from the 304 stainless steel material, the Teflon will also be worn during use to produce abrasive debris. This abrasive debris will reduce the battery capacity, and the existing vibrating screen machine is not convenient for quick disassembly and maintenance of the screen.
