We have developed a helix dryer specifically designed for lithium-ion battery recycling. The system efficiently removes low- and high-boiling solvents from heterogeneous shredded materials, enabling high black mass purity and safe, stable operation.

Based on proven contact dryer technology, the solution uses indirect heating under vacuum in an inert, closed-loop environment to ensure reliable processing of variable feed materials. Optimized heat transfer, uniform mixing, and integrated filtration deliver high evaporation efficiency, minimal product loss, and flexible batch operation across different battery chemistries.
