The Solidmix technology (photo) is suitable for the pre-drying of shredded battery scrap and has been optimized for the separation of the solvents contained in the batteries. By means of vacuum drying, the solvents can be quickly and reliably separated from the battery scrap. Continuous mixing of the material to be dried ensures optimal heat transfer and distribution in the equipment, which further increases the efficiency of the drying process. Due to the modular design of the dryers, it is possible to easily scale up to larger drying capacities. Usual capacities are in the range of 0.5–4 ton/h. The separation of the electrolytes facilitates the downstream hydrometallurgical treatment of the so-called black mass, which contains the valuable cathode and anode materials. — Ekato Systems GmbH, Schopfheim, Germany
