Scrap lithium battery recycling equipment can sort out copper and aluminum, positive and negative electrode powder and other valuable metals, which can give some reprieve to the few raw materials. Usually a complete waste lithium battery recycling mainly has four parts: receiving loading crushing system, (drying) pyrolysis system, sorting system and tail gas treatment system.
Waste lithium battery feeding crushing system includes closed insulation climbing conveyor, closed air preservation shredder, closed air lifting feeder, closed metering bin four groups of equipment composition. Due to the lithium battery in the crushing process is prone to instability, in the feeding and crushing process using a closed space and add protective gas under the way of crushing, shredding.
Crusher closed to the lithium battery positive ji material in the inert gas protection under the particle size crushing to about 25MM. Materials are transported to the shredding system through closed metering, the shredding equipment is closed to prevent dust leakage in the shredding process; the equipment is also equipped with automatic replenishment of inert gas to reduce the oxygen content in the crushing system, the oxygen content can be reduced to a reliable value of 5% or less, inert gas can prevent the oxidation reaction combustion detonation and reduce the temperature of the material (conventional nitrogen and carbon dioxide) to prevent sparks from exploding during the crushing process
