With the rapid development of electronic technology, the recycling of lithium batteries has become more and more important, the waste lithium batteries in our daily life will cause great pollution to the environment if not handled properly, the waste lithium batteries contain a lot of metal materials, and this is a very marketable material, but it is necessary to go through professional lithium battery recycling treatment before it can be disassembled and separated and recycled. Waste lithium batteries will contain cobalt, lithium, nickel, copper, aluminum and iron and other gold elements, of which the mass fraction of cobalt ions can be as high as about 15%, which is 850 times the content of associated cobalt ore, far beyond the output of China's cobalt mines.
Xingmao Machinery's waste lithium battery recovery and recycling equipment is a popular environment-friendly equipment. The positive electrode material, negative electrode material, diaphragm and electrolyte of used lithium battery, the positive electrode material accounts for 40% of the whole lithium battery production cost, and the characteristics of the positive electrode material have a great impact on the performance of lithium battery, the lithium positive electrode material is the core of the whole lithium battery. The developed waste lithium battery recycling and disposal device is a process of dry treatment using physical method. Resources are extracted from the waste lithium batteries and reused in the market cycle. The whole process of waste battery treatment crushing and recycling process has a high recovery rate and is a high net production and processing equipment line.
Waste battery treatment crushing recycling process is divided into waste lithium battery feeding, oxygen-poor crushing, oxygen-free cracking, sorting, friction de-powdering sieve, comprehensive utilization of exhaust gas, exhaust gas treatment and purification, etc. The exhaust gas treatment is processed by high-temperature combustion, which meets the requirements of environmental protection emission, and the heat after the combustion of exhaust gas is used for secondary use. The equipment is flat and movable, no foundation is needed. The resource utilization rate of gas is high. Equipment with double nitrogen insulation measures and explosion-proof system to prevent the occurrence of explosive deflagration. Lithium battery recycling equipment can process about 1.3-1.6 tons of charged lithium batteries per hour.
After the waste battery treatment crushing recycling process to recover the waste lithium battery, you can sort out copper and aluminum, positive and negative electrode powder, diaphragm and other recyclable recycling materials. It is of great social and economic significance to invest in complete sets of waste lithium battery recycling and treatment equipment to recover valuable metals from lithium-ion batteries, reduce pollution caused to the environment and alleviate the scarcity of resources.
