Mixing System No. 1

The
intensive
mixer.

The original Eirich machine. A rotating pan, an eccentric tool, two independent drives, an optional vacuum hood. Every recipe Eirich runs, from a 0.1 litre laboratory trial to a 12,000 litre production batch, sits inside this geometry.

The principle

The principle
in four
movements.

The intensive mixer is not a stirrer with extra features. It is a closed system of four motions, each independently adjustable, each tuned per recipe.

01

The rotating pan

An inclined pan carries the entire batch in one direction at a tunable 5 to 50 rpm. The whole charge passes the tool on every revolution.

02

The eccentric tool

A mixing tool sits off centre and rotates against the pan. Tip speeds reach 40 metres per second, but only where the geometry asks for it.

03

Independent drives

Pan and tool run on separate motors. Energy input is decoupled from throughput, so a recipe is tuned in joules, not in guesswork.

04

Vacuum and temperature

An optional sealed pan reaches 10 mbar and accepts heating or cooling. Drying, degassing and reactive mixing run inside the same machine.

Specification

Numbers
carefully set.

Pan, tool, drive and cycle scaled across four size classes. Final figures depend on the recipe and the chosen variant. The Hardheim Technikum confirms them on your real material.

Variants

Five
geometries.

  1. 01

    Standard

    Fixed pan, top loaded, bottom discharge gate. The reference geometry behind every other variant.

  2. 02

    Hinged

    The mixing head pivots clear of the pan for fast cleaning, recipe changes and visual inspection.

  3. 03

    Tilting

    The pan tilts to discharge by gravity. Right for sticky pastes, friction linings, carbon and refractory bodies.

  4. 04

    MixSolver

    Dissolving and dispersing variant. High shear tool geometry for slurries, paints and battery slips.

  5. 05

    Evactherm

    Vacuum and temperature controlled pan. Drying, degassing and reactive mixing in one closed cycle.

Capability

Eight processes,
one machine.

A single intensive mixer covers the work that elsewhere takes a line of separate units. Recipe choices, not new equipment.

Mixing

From gentle folding to severe shear, tuned per recipe.

Granulating

Build pellets and granules in a single pass.

Kneading

Pastes, doughs, friction compounds, brake linings.

Dispersing

Break agglomerates into primary particles.

Coating

Apply binders and fines onto carrier particles.

Drying

Evaporate moisture under vacuum, in cycle.

Vacuum mixing

Down to 10 mbar, degassing while mixing.

Reactive mixing

Combine heat, vacuum and shear in one pan.
