Waste lithium battery positive and negative electrode recycling line
Release Time：2022-11-08 Source：Battery Recycling Machine Share：
It is a kind of environmental protection lithium battery positive and negative piece recycling equipment, whose function is to extract and separate the various rare metal materials contained in the scrap lithium battery positive and negative pieces, and the whole set of scrap lithium battery positive and negative piece crushing and sorting production line has a combination of several single machines.
The whole set of waste lithium battery positive and negative electrode crushing and sorting production line has twin shaft shredder, secondary crusher, vibrating feeder, grinding machine, classifier, airflow sorter, pulse dust collector and so on.
After shredding, the shredded materials will be conveyed to the crusher for secondary crushing through the conveyor, and the crushed materials will be conveyed to the grading screen for screening under negative pressure.
Second, the screened material is conveyed to the mill for crushing treatment, and after crushing, it is conveyed to the vibrating screen for secondary screening, and the black powder is screened out.
Third, the fine powder discharge port of the classifier is connected with the air inlet of a cyclone downcomer, and the coarse powder discharge port is the discharge channel of aluminum particles.
Fourth, the dust removal port of the vibrating feeder as well as the second vibrating feeder are connected with the air inlet of the second cyclone downcomer, and the dust discharge port of both the cyclone downcomer and the second cyclone downcomer are the discharge channels of the black powder.
The dust removal port above the single machine is connected to the main pipe of pulse dust collector, and the whole production line is handled in an environmentally friendly physical way.
The crusher is a hammer crusher, and there is a crushing chamber inside the mill, and the inlet and outlet of the mill are connected with the crushing chamber, and there is a screw conveyor inside the inlet of the mill, and there is a fixed knife and a moving knife rotating circumferentially inside the crushing chamber of the mill, and there is a grading impeller rotating circumferentially inside the crushing chamber between the outlet of the mill and the fixed knife and the moving knife.
The black powder is effectively recovered in the whole crushing process of the scrap lithium battery positive and negative electrode crushing and sorting production line, which greatly improves the recovery rate of black powder and reduces the proportion of black powder in the aluminum particles, and with the physical density difference between black powder and aluminum, the black powder separated from the battery electrode scrap is recovered by negative pressure in each step, which has a high sorting effect and can recover the black powder and aluminum particles with high purity. The sorting effect is high, and the black powder and aluminum particles can be recovered with high purity.
