Safe material feeding and storage of raw materials play a crucial role in the production of battery materials. Zeppelin Systems offers comprehensive raw material logistics—from sacks, drums, and big bags to full truck unloading—always tailored to the specific, including abrasive, properties of the raw materials.

Our systems are designed in accordance with locally applicable explosion protection regulations. Carefully aligned containment concepts, adapted to prescribed occupational exposure limits, ensure optimal operator safety—even when handling toxic substances.

With our Smart Storage Solution, you're also equipped for Giga Factories. Storage volumes can be easily tailored to your specific needs and scaled up at any time—helping to prevent material shortages caused by disrupted supply chains.

For fast, efficient discharge—without bridging, sticking, or leftover residues—you can rely on our specially developed discharge aids, ensuring smooth and reliable operations.

Whether from sacks, big bags, or octabins—Zeppelin Systems ensures the dust-free feeding of raw materials by relying on our in-house developed dedusting systems or by partnering with renowned filter manufacturers. This allows us to respond precisely to your specific requirements and always select the most suitable solution.

Our jet filters with automatic cleaning, for example, prevent unwanted material loss by returning collected dust directly into the process—eliminating the need for frequent filter changes. This not only reduces maintenance costs but also minimizes product waste.

In addition, our Safe Change concepts ensure that operators are protected from exposure to toxic and respirable substances—guaranteeing safety and compliance at every stage of your process.

Zeppelin Systems mixers have been established in industrial mixing technology for 70 years and are used in various industries for different mixing processes.

The Zeppelin FM intensive mixer is ideal for the high-quality, reproducible, and safe production of battery compounds using dry and semi-dry mixing processes. High speeds, the design of the mixing tool, and the construction of the mixing vessel achieve extremely high shear rates. These enable highly efficient dispersion and homogenization of the raw materials. Different process parameters (e.g., individual shear rates, precisely controllable temperature profiles, etc.) allow nanoparticulate conductive additives to be effectively dispersed and finely distributed, and binding materials to be specifically activated and fibrillated. Depending on the base materials, the bulk density and energy density can also be increased. In addition, the FM intensive mixer from Zeppelin Systems offers individual wear protection, which ensures a long service life even with abrasive raw materials.

For the continuous and consistent feeding of electrode slurry onto the calender rolls, a special dosing unit with a feed chute and continuous level monitoring has been developed. The chute is directly coupled to the calender roll and can move linearly along with it.

By ensuring that material is always available in the chute, the system prevents the calender rolls from running empty. The optimized geometry of the chute effectively prevents bridging, while significantly reducing the line load on the calender rolls—ensuring smooth, uniform coating and improved process reliability.

At our mixing technology test center in Kassel, processes are tested and further developed—from individually configurable laboratory mixers to production-scale systems. For example, we have carried out comprehensive test series for various anode active materials (AAMs) and cathode active materials (CAMs).

These trials included materials such as LFP, NCA, NMC, SiC, SiOx, and a wide range of graphites and binders. The tests were conducted in collaboration with renowned industry customers and leading international research institutions, ensuring application-driven results and high scalability.
