Introduction to Dry Recycling and Treatment Methods for Waste Lithium Battery Recycling and Treatment Equipment

Scrap lithium batteries refer to batteries that have been used and discarded. Scrap lithium batteries pose serious environmental hazards and should be centrally recycled. Scrap battery recycling refers to the reuse of used batteries through recycling. Lithium ion batteries are usually composed of battery covers, battery shells, positive electrodes, negative electrodes, electrolytes, separators, and other components. The recycling and utilization of waste lithium batteries can effectively avoid environmental pollution.

The lithium battery recycling and processing equipment crushing system and its process implementation effectively recover copper foil and aluminum foil from waste lithium battery crushing materials. The entire process is very meticulous. Firstly, the waste lithium batteries are transported to the battery crusher through a conveying mechanism, and then rough crushing is carried out. During the rough breaking process, inert gas is introduced to suppress the ignition. Afterwards, the crusher will discharge the electrolyte mixed in the roughly broken material into the condensation recovery system for condensation recovery. Next, the material is transported in a fully enclosed manner to a low-temperature baking furnace for drying and evaporating the electrolyte. After a first stage hammer grinding and a second stage grinding, the copper aluminum foil is kneaded into spherical particles. In addition, synchronous magnetic separation is also carried out during the lower stage of transportation to separate the steel shell; The materials after air separation enter the drum screen for sorting, and the powder mixed with positive and negative electrodes is output. The powder is collected by ton bags. The exhaust gas is discharged into the exhaust gas treatment system, and after cooling, washing, UV photodegradation, and activated carbon treatment, it meets the emission standards and is discharged into the atmosphere. This set of waste lithium battery recycling and treatment equipment and its process are both environmentally friendly and efficient.
At present, the main dry recycling method for power lithium batteries is the mechanical crushing and sorting method, which involves physically and mechanically disassembling waste lithium batteries and separating them to obtain valuable materials such as copper foil, aluminum foil, and electrode powder.
