Lithium Battery Recycling Crushing and Carbonization Equipment

<sup>Introduction to lithium battery recycling pyrolysis furnace
Jiutian Machinery's lithium battery continuous pyrolysis carbonization furnace can continuously feed and discharge materials without flue gas pollution. Together with other crushing and sorting equipment, the copper and aluminum metals in waste lithium batteries can be sorted to obtain copper. Powder, aluminum powder and black powder can obtain higher value.

Lithium batteries include columnar, soft-packed, framed, etc. According to their uses, they include mobile phone lithium batteries, computer lithium batteries, car lithium batteries, energy storage lithium batteries, etc. If you want to recycle scrapped lithium batteries, you need to clean the positive and negative electrodes. Materials are sorted.
The main components of used lithium-ion batteries include: positive and negative electrode powder, steel shell, copper and aluminum, electrolyte, binder and separator plastic. After the waste lithium battery is broken, the separator, copper foil negative plate, aluminum foil positive plate, casing, electrolyte, etc. can be separated. After the battery is broken, a lot of black powder will fall out. Because there is adhesive on the copper foil and aluminum foil, part of the black powder will stick to the copper foil and aluminum foil, making it difficult to recycle. The separator material will not disappear, and the electrolyte will evaporate after the battery is broken. Drop part of it.
The lithium battery continuous carbonization furnace can also pyrolyze the adhesive on the separator and the positive and negative plates, and vaporize the electrolyte, thereby increasing the recycling rate of waste lithium batteries. At present, waste lithium batteries are processed, recycled and sorted using the carbonization process to process positive and negative mixed lithium batteries.</sup>

Lithium battery recycling pyrolysis process

<sup>Lithium batteries need to be discharged. After discharge, the waste lithium batteries are crushed to about 10cm and then enter the carbonization furnace through a conveyor. During the carbonization process, the separator is directly carbonized, the electrolyte is pyrolyzed and gasified, and the adhesive is gasified. Because the furnace is almost a closed space, it meets anaerobic conditions, so that the diaphragm, adhesive, and electrolyte are heated up inside the carbonization furnace for pyrolysis and gasification. The generated flue gas passes through the recovery pipe and flue gas purification system to achieve reciprocation. Effect of cyclic thermal decomposition. During the initial carbonization preheating, the plastic diaphragm begins to carbonize and pyrolyze, the electrolyte reaches gasification, and finally pure copper, aluminum and black powder are obtained, and then the aluminum and copper powder are separated through the screener, crusher, and sorter. Use the magnetic separator to separate the iron shells.

Jiutian mechanical pyrolysis machine is suitable for tires, electronic waste, oil wires, enameled wires, capacitors, circuit boards, aluminum-plastic panels, metal zippers, lithium batteries, aluminum cans, plastics, etc.</sup>
