§ Hardheim, Germany
§ 01 Material preparation / seven decades deep

One mixing principle. From a tenth of a liter to twelve thousand.

Eirich builds intensive mixers on a single patented principle: a rotating pan and an eccentrically mounted tool, each driven independently. The result is laboratory process fidelity at gigafactory scale, across fifteen heavy industries.

§ 04 Where it runs

Fifteen industries. One mixing principle at the heart of each one.

From lithium cathode slurries to molten aluminium anode paste, the same patented pan-and-tool principle delivers repeatable, measurable process control.

§ 05 The principle / explained

Two axes. Two speeds. Total process control.

A pan rotates about its own vertical axis. A mixing tool, positioned eccentrically and driven on its own shaft, turns against the flow. The independent drives let a process engineer adjust energy input and shear without changing the geometry of the vessel.

That single idea scales. A 0.1 liter laboratory unit and a 12,000 liter production machine share the same operating principle, so a recipe validated on the bench translates cleanly to the plant. Process fidelity is not inherited from a formula sheet. It is engineered into the mechanics.

A / Pan axis
Rotation. Material transport.
B / Tool axis
Eccentric. Shear and energy input.
