The EIRICH mixer with its unique working principle offers fantastic possibilities along the entire process chain, from the production of raw materials and the preparation of system mixes to particle design for many different electrical energy storage systems. Often it is possible to integrate complicated and expensive process chains consisting of several preparation machines into a single processing unit. One outstanding characteristic of the special EIRICH mixing principle is the flexibly adjustable energy input. This enables the mixer to be used for the dispersion of raw materials. In the...

EIRICH offers innovative, efficient preparation processes for the production of not only raw materials but also cathodes, anodes and separation layers. Depending on the particular case, the mixes are further processed by pressing/ compacting, extrusion or coating. The basic materials for the further processing are either homogeneous bulk powders, granules, plastic extrusion mixes or suspensions/slurries. Particularly where plastic bodies and suspensions are concerned, there are advantages in using the EVACMIX® process. Preparation with absolutely no bubbles is possible. Intelligent use of...

The advantages of the unique EIRICH mixing system 1 Stationary, vacuum-tight casing 2 Rotating mixing pan 3 Processing chamber 5 Wall-bottom scraper 6 Discharge opening *Geometry and configuration depending on the application

The special characteristics of the EIRICH intensive mixers are ■ the rotating mixing pan ■ the stationary wall-bottom scraper ■ the high-speed mixing tool in eccentric position to the mixing pan center The unique working principle of the EIRICH intensive mixer The EIRICH mixer differs from other mixing systems available on the market by its rotating mixing pan with built-in eccentric mixing tool. Material is transported through the rotating mixing pan to the mixing tool and is not trapped in any dead spaces. A stationary wall-bottom scraper directs material accumulations on the pan...

Process control and instrumentation technology EIRICH develops and manufactures its own machine and process control solutions for preparation systems. This offering includes both new installations and the modernization or expansion of existing machines and lines. All components are configured for the user's requirements. The results are tailored solutions which extend from the simple machine controller to batch controllers with formula management. Special software packages round off the control hardware. They include e.g. online documentation with proactive planning of maintenance measures,...

The right mixer for all performance classes The EIRICH range of mixers includes sizes from 1 to 12,000 liters, which meet user-specific requirements with great efficiency. Thanks to the high efficiency and filling variability, relatively small mixer volumes are sufficient for even the high production outputs in the battery industry. Depending on the solvents or solid materials used, the mixers are available in an explosion-protected version with optional nitrogen inertization. *EVACMIX® vacuum technology cannot be retrofitted! **in 3-shift operation with 4 batches/h
