Prior information notice without call for competition: Miscellaneous special-purpose machinery Description of the procurement: As part of the FFB, a mixing line with a corresponding dosing system is required for the sample line . The mixer is said to be operated in a batch process and to be able to produce both anode and cathode materials. A batch mixer with a material throughput of approx. 3 to 40 l / h is required for the production of the electrode materials. Dosing system: The delivery of solid active materials for the cathode (NCA, NMC111, NMC622, NMC811, NMC9XX, LNMO, LCO or LFP) and anode (graphite, silicon) should take the form of bags or big bags. Using suitable devices / systems, the raw materials should be fed into intermediate containers or directly into the dosing system, taking into account the necessary safety and protective measures. Solvents such as NMP (N-methyl-2-pyrrolidone) or distilled water should be made available in tanks and fed to the system via pipes. Gravimetric dosing is planned for the solids, while liquids are to be added to the mixer at a constant time using pumps and flowmeters (e.g. volumetric dosing). The control of the dosing devices should be digital (IT interfaces) and linked to the mixing process. Mixer: The cathode materials should always be processed using organic solvent NMP (N-methyl-2-pyrrolidone), while the anode materials should be processed with distilled water. The mixer should process both anode material (e.g. graphite, silicon) and cathode material (e.g. NCA, NMC111, NMC622, NMC811, NMC9XX, LNMO, LCO or LFP) and must be designed accordingly for aqueous and solvent-based dispersions, as well can be quickly converted. All in all, the mixing processes should be easily scalable and also be able to work under partial load (20 to 30% of the maximum nominal throughput) without having any influence on the quality of the suspension. The process times for a finished batch should be in the range of a few hours. The material should be added to the mixing container from above and the finished suspension should be able to be conveyed to the coating system in a simple manner using the transport pipes / containers, with the aim of simple and efficient cleaning of the mixing system. The characterization of the electrode pastes during the mixing process should be carried out using an in-line rheometer. In addition to a fully automated cleaning system, the system should also have appropriate IT interfaces (OPC UA) to digitally analyze the process data. Typical set-up times should be less than an hour and independent of up-scaling.
