Battery Recycling

Black mass drying is crucial for reducing solvent content, which is essential for efficient black mass processing. This reduction enhances the material’s value, optimizing subsequent recycling and resource recovery.
EKATO SOLIDMIX features:
EKATO builds the systems “technically tight” and thus minimizes the strain on the environment and the operator. The environment is not exposed to the solvents – this simplifies any explosion protection measures.
The HF resistant EKATO Solvent Recovery System (SRS) allows highest recovery rates of the typical electrolytes in the recycling industry – adding to your recovery rate balance. In the EKATO pilot plant, the drying process can be reproduced on a small scale. The focus here is on optimizing the processes.
Solvent residues that cannot be separated (VOC) are processed in a downstream exhaust gas treatment system. The EKATO dryer has a highly efficient solvent recovery system. This means that the downstream exhaust gas treatment system can be very cost-effective.
The EKATO drying process removes the common solvents in black mass (water, EC, EMC, DMC). The drying principle works on purely physical principles (temperature, pressure, time and shear). This means that the EKATO drying system can dry any solvent that follows these basic physical principles. With the EKATO drying system you are flexible and equipped for the future.
Black mass can be dried cost-effectively to a low moisture content. This significantly increases the resale value. The absence of organic solvents in the black mass is essential for further processes in hydrometallurgical processing.

Cathode and anode slurry drying is crucial when mechanical dewatering reaches its limits. Vacuum contact drying is the optimal choice, achieving minimal moisture levels and maximizing yield. Our equipment is designed to minimize product loss, featuring a single-pot design that seamlessly transitions from slurry preparation to vacuum drying, ensuring efficiency and high-quality output in battery recycling processes.
EKATO SOLIDMIX features:
Before thermal drying, the slurry should be pre-dried by means of mechanical dewatering. This is often not possible. The EKATO Vacuum dryer can also be used to pre-evaporate the slurry (Fed Batch Process). The evaporated solids cake is finally dried in the same apparatus in a deep vacuum to the final moisture content.
