Discarded lithium batteries contain a large amount of non-renewable heavy metal resources with high economic value. The positive electrode material of lithium batteries is lithium cobalt oxide powder, and the negative electrode material is graphite powder. Both the positive and negative electrodes contain a large amount of metal materials such as cobalt, nickel, manganese, copper, and aluminum. If discarded or unqualified lithium batteries can be effectively recycled and processed, it can not only reduce the pressure of waste batteries on the environment, but also avoid the waste of heavy metal resources such as cobalt, nickel, and manganese. Therefore, due to resource constraints and the need to govern the environment, countries around the world attach great importance to the recycling of waste lithium batteries.
In the process of recycling and treating waste lithium batteries, dry recycling technology and wet recycling technology are mainly used. Among them, the wet recycling technology has a long process route, large investment, and many equipments. It cannot recycle the metal aluminum, and the wet process cannot treat the PVDF in the lithium battery; dry recycling technology is mainly divided into high-temperature (~800℃) dry technology and low-temperature (~400℃) dry technology. The dry recycling technology has a short process route and few equipments. It can effectively treat the PVDF, but it has high energy consumption and consumes a lot of heat. Dry treatment must produce acidic gas HF (or other hydrogen halide gas) and organic cracking waste gas, which need to be treated separately, otherwise it will have a great impact on the environment and require huge investment in environmental protection facilities; lithium battery recycling and processing equipment includes disassembly line (reuse at the ladder) + grinding and crushing air selection line + extraction (re-extraction) production line, among which the grinding and crushing air selection line (i.e. powdering line) is the heavy Among them, the powdering line of waste lithium batteries is the key to the complete set of lithium battery recycling and processing equipment, but many domestic manufacturers still apply the process of a certain place, that is, shredding + secondary crushing, grinding + air separation (external purchase of high and medium temperature furnaces), which does not solve the flammable and explosive problems of charged waste lithium batteries from the source, and the processing cost is close to 3000.00 yuan/ton. We have introduced advanced foreign technology and carried out technological reforms. The feeding part of the self-produced high-temperature pyrolysis furnace is designed with variable frequency speed regulation to form a high-temperature vacuum belt, which fundamentally solves the fire and explosion problems of the shredder, and greatly reduces the equipment and its production and operation costs. This unique process of lithium battery recycling and processing equipment production line does not use nitrogen and other oxygen-isolating gases, thereby greatly reducing the equipment and production and operation costs. Therefore, we solemnly and sincerely launch cooperation forms such as rent-to-buy and OEM contracting. Welcome to inquire!
