Short Description
The GHD-LIB 4000 is a helix dryer designed for lithium-ion battery materials. It operates under low-pressure, elevated-temperature conditions to gently remove electrolyte. The rotating helix screw ensures continuous material movement for uniform drying, while the vertical design supports compact integration in recycling systems. The process minimizes HF formation and supports safe, efficient thermal treatment prior to downstream processing.
Technical Parameters
Product Information in Detail
- The GHD-LIB 4000 is a vertical, deep vacuum batch dryer designed specifically for lithium-ion battery recycling.
- With a product chamber volume of ~5 m³ and a filling capacity of up to 4,000 liters per batch, it plays a key role in the Material Separation stage by extracting solvents and moisture from shredded battery material with high precision and safety.
- This dryer can operate under deep vacuum conditions which significantly lowers the boiling point of the solvents present in battery materials. The result is efficient drying at low temperatures (below 80 °C), reducing thermal stress on the material. The process is designed to effectively minimize HF (hydrogen fluoride) formation, improving process safety and environmental compatibility.
- The agitation system is specially engineered for shredded lithium-ion batteries. Its unique, low-speed agitator ensures uniform product movement and efficient solvent removal without damaging the sensitive materials. The agitator rotates clockwise only, as reverse motion could compromise seal integrity.
- The unit is purged with nitrogen before each cycle to maintain an inert atmosphere, ensuring safe startup and operation. The drying process occurs under vacuum, and nitrogen remains present at all times for added safety. ATEX-rated sensors are included where required.
- The drying process itself can be adapted to suit different battery chemistries and operating conditions. While the current setup is optimized for low-temperature drying under vacuum, the system design allows for modification depending on process requirements.
