Intensive Mixer Type RV12

The Eirich Intensive Mixer Type RV12 is a batch-based intensive mixer designed for wet and dry mixing processes in industrial-scale electrode production. It mixes active materials, binders, additives and solvents into a homogeneous electrode slurry, or dry powders into a structured dry electrode mix. Typical production batches range from 400 to 500 L usable capacity, depending on the application.

The RV12 is used in the Battery Cell Manufacturing Process, specifically Electrode Manufacturing: 1.1 Wet Mixing and 1.5 Dry Mixing/Coating.

Core Mixing Technology

The RV12 uses a horizontal, rotating mixing pan with an eccentric high-speed rotor. This separates material transport (pan) from energy input (rotor) and allows precise control of shear energy for carbon coating and binder fibrillation while minimizing unwanted particle degradation.

Replacing planetary mixing lines that run for several hours with compact batch systems reduces building size and energy costs.

Scale-Up & Process Validation

Due to consistent mixing geometry, results from the EL1nano (0.1 L) or Intensive Lab Mixer EL5 (5 L) transfer linearly to production-scale volumes. Customers can perform 500 L trials using the Intensive Mixer RV12 to confirm product quality and cycle times under real-world industrial conditions at Eirich Test Center in Germany or at a dedicated partner like UKBIC.

Reference Cases

• ACC (Automotive Cells Company): Eirich assisted in the smooth ramp-up of their European Gigafactory production.
• UKBIC (UK Battery Industrialisation Centre): Utilization of the RV12 for 1:1 scale pilot productions.

Eirich has partnered with TU Braunschweig (iPAT) and various EU research consortia (e.g., Prozell) for perfecting dry electrode coating and carbon coating. The RV12 is engineered and manufactured in Germany (Hardheim).
