Waste lithium battery recycling equipment: solving recycling problems and activating new value of resource recycling
The equipment adopts an advanced preprocessing system, which first safely discharges the battery to avoid the risk of short circuit, and then separates the outer shell from the battery cell through a shell stripping machine.
Low temperature drying removes organic solvents from the electrolyte, reducing the risk of subsequent processing.
The crushing and sorting process is even more crucial.
The charged crusher can directly crush charged batteries under nitrogen protection or anaerobic environment, which not only avoids the traditional dismantling danger, but also increases the recovery rate to 98%.
Subsequently, the multi-stage sorting device demonstrated its capabilities by utilizing technologies such as magnetic separation, airflow separation, and eddy current separation to accurately separate components such as copper and aluminum current collectors, black powder, and separators.
The pyrolysis and material separation systems are equally excellent.
The high-temperature pyrolysis furnace decomposes organic matter in an oxygen free environment at 400-750 ℃, causing metal and non-metal dissociation, with a black powder recovery rate of ≥ 99%.
Chemical leaching equipment can perform acid or alkali leaching on black powder, and the recovery rate of metals such as lithium, cobalt, and nickel can reach over 95%.
Subsequent metal refining aims to achieve a purity of over 98% for copper and aluminum.
At the same time, a comprehensive exhaust gas purification system adopts technologies such as spray towers and activated carbon adsorption to ensure emissions meet standards.
By using our equipment, a large amount of metals such as cobalt, nickel, and lithium can be extracted from every 10000 tons of waste lithium batteries, with a market value of tens of millions of yuan. This truly achieves a win-win situation between resource recycling and economic benefits, and helps the environmental protection industry reach new heights.
