Process flow of equipment for crushing and sorting waste lithium-ion battery cell units

The process flow of equipment for crushing and sorting waste lithium-ion battery cell units generally includes the following steps:

Crushing: The waste lithium-ion battery cell units are sent into a crusher and mechanically crushed into small particles.

Separation: The crushed waste lithium-ion battery cell fragments are sent into equipment such as a vibrating screen or an air separator, in order to separate particles of different sizes and densities by screening or physical principles such as gravity or wind.

Magnetic separation: The particles screened and separated are then sent into a magnetic separator, where the adsorption effect of magnetic materials on heavy metals such as iron, cobalt, and nickel is used to achieve the separation and recovery of these elements.

Froth flotation: Particles that have not been separated by magnetic separation are sent into a froth flotation machine, where chemical reagents are added under specific conditions according to the mineral surface's hydrophilicity and hydrophobicity to realize the separation and extraction of valuable elements again.

Electrochemical recovery: Through the overall reaction formula of electrolysis, beneficial elements such as lithium, cobalt, nickel, and manganese are recovered, and the waste liquid is further treated. Meanwhile, other residual valuable elements are also recovered, achieving maximum resource utilization.

The entire process needs to be strictly controlled and monitored to ensure effective recycling of waste lithium-ion battery cell units and environmentally friendly disposal.
