Lithium Battery Recycling Machine High Temperature Pyrolysis

Products Detail

Lithium battery recycling equipment recovers valuable metals and materials through high temperature cracking and crushing recycling method. It adopts various sorting methods, such as pyrolysis, screening, wind sorting, gravity sorting and so on. Recover out black quality, copper powder, aluminium powder and so on. Improve the recovery rate and purity of black powder. Industrial automation can be realised . High recovery efficiency, high processing capacity, recovery rate can reach more than 98%. Dismantle and separate the batteries, and the battery packs such as electrode actives, collectors and battery shells are pre-treated, pyrolysed, crushed, magnetically selected, flexibly crushed and sorted. Thus obtaining high-value metal materials. Effective separation of waste battery components to achieve the resourceful use of waste lithium batteries.

Working principle: High temperature pyrolysis is a preliminary separation of physical crushing and so on. Then after high-temperature roasting decomposition, the organic binder, electrolyte removal. Carbonised PVDF, thus separating the lithium battery constituent materials. At the same time lithium battery in the metal as well as other compounds oxidation reduction and decomposition. Volatilisation by vapour. Then collected by condensation and other methods. Waste lithium batteries pass through the oxygen-free charged shredder. Pole piece diaphragm, plastic, etc. into the oxygen-free cracking furnace. Cracking furnace system adopts inert gas protection system. Ensure that the furnace body is in an oxygen-free state. Electrolyte is discharged and heated in the furnace body.

Combustible gas and organic waste gas at the back end of the cracking are burned. The furnace is heated so as to achieve comprehensive calorific value reuse of the combustible gas. The positive and negative electrode sheets after cracking enter the de-powdering system. Then it is crushed, pulverised, air-selected, screened and gravity sorted to separate the black matter, iron and copper, aluminium and iron separately. The waste gas generated after cracking. Then through the combustion chamber, cooling tower, dust collector, spray tower, RTO, chimney discharge, etc., the exhaust gas is purified and discharged to meet the standard.  

Raw Materials

Lithium batteries, lithium ternary batteries, lithium cobaltate batteries, lithium iron batteries, mobile phone batteries, car batteries, laptop batteries, etc.

Advantageous

1. The whole set of equipment adopts advanced technology, stable equipment performance and high processing capacity.

2. automated recovery and separation, featuring rapid separation, high recovery efficiency and high degree of automation in resource recovery

3. Thorough pyrolysis, clean and thorough removal of electrolyte and binder. Prevent the pole piece and diaphragm from adhering to black powder.

4. It can realise charged crushing and early recovery of PVDF, and reduce the pressure of waste gas treatment and emission during pyrolysis.

5. Combination of dynamic and static screening is adopted. And improve the recovery quality of black powder, copper, aluminium and other materials.

6. Adopting unique fine crusher and shredder. It can fully strip the black powder on the pole piece, which is more conducive to the sorting of copper foil and aluminium foil.

7. Humanised design, PLC intelligent control system can be adopted, easy to operate and maintain.
