Various machines and system concepts for battery recycling

Efficient battery recycling at the highest level

With the rapid development of lithium-ion batteries, the demand for rare metals such as cobalt, manganese, nickel and lithium is also increasing enormously. As these resources are limited, recycling from returned batteries is becoming increasingly important.

Thanks to our extensive range of machines, which includes various shredding technologies such as single and twin-shaft machines, hammer mills and special solutions, we offer tailor- made system concepts for different requirements. From simple solutions in dry or wet processes for battery processing to large- scale complete systems for complete material separation, we supply the right technology.

Our machines and systems are designed for throughput rates of 50 kg to 5 tons per hour and enable efficient and sustainable recovery of valuable raw materials.

 

Technical features of ERDWICH lithium-ion battery shredders:

  • Delivery & unloading
    Modules and complete packs are delivered on conveyor lines without prior disassembly. A specialist checks the residual voltage and, if necessary, discharges them to 0volts for maxi- mum fire safety.
  • Pre-shredding & separation 
    ​​​​​​​
    In a nitrogen-inert environment, the battery packs are first shredded to 50 x 100-150 mm using a twin-shaft shredder and then further processed to a definable piece size.
  • Drying & sifting
    An air classifier separates light and heavy materials. Magnetic and eddy current separators separate ferrous and non-ferrous metals, while aluminum and copper foils with black mass adhesion as well as foil material are prepared for further processing.

  • Final separation & processing
    Multi-stage sifting separates black mass, metals and plastics with maximum purity for recycling.  

Safety & sustainability

High-performance filter systems ensure dust-tight processing and avoid health risks for workers.

To avoid the risk of fires and explosions, the system works with controlled nitrogen inertization. ERDWICH was able to draw on its many years of experience in e-waste and hazardous waste recycling. By precisely controlling the nitrogen supply, the oxygen content is kept constantly below 3% to prevent thermal runaway (exothermic reactions).

However, ERDWICH also offers wet processing systems in which the material is bound in a liquid, usually water, during the shredding process. This prevents the risk of fire and explosion and minimizes the release of dust. The optimum processing technology is always selected on a project-specific and applica- tion-oriented basis in order to achieve the best results for the respective recycling process.

Unique selling points & future prospects

The high process reliability and efficiency of the system are particularly appreciated. With this solution, ERDWICH is setting new standards in the industry and positioning itself as a techno- logy leader in the field of safe and sustainable battery recycling. The increasing demand for recycling solutions for lithium-ion batteries shows: This is a market with enormous future potential – and ERDWICH is ideally prepared for it.

Systems for batteries

Technologically leading solutions for shredding and processing batteries.

Shredding of small lithium-ion batteries

Laboratory crushing of small lithium-ion batteries from laptops incl. plastic and aluminium housings.

The material is fed, in smaller quantities by hand, directly into the hopper above the cutting unit. The hopper is equipped with a pneumatic press-in device that feeds parts that are difficult to grasp into the cutting process. The material is shredded between the stator and rotor knives. It falls down into a box provided by the customer.

Intended purpose

Shredding of small lithium-ion batteries from laptops incl. plastic and aluminium casings.

Final grain size <= 20 mm
