MAIN ASSEMBLY / SHEET 03
The intensive
mixer.
The patented counter-rotation principle, sheet by sheet. An inclined pan turns one way. An eccentric tool turns the other. Two independent drives. One machine that scales linearly from a 0.1 litre laboratory unit to a 12,000 litre production cell.
PAN DIA.
0.35 to 4.0 m
TOOL SPEED
up to 40 m/s
VACUUM
down to 10 mbar
TILT ANGLE
30° standard
CYCLE
2 to 12 min
MAX BATCH
12,000 L
P / PRINCIPLE
Two motions.
One mixing event.
Patented in 1903 by Gustav Eirich. Drawn the same way ever since. Four operating notes describe the entire principle.
01
Pan rotates one way
An inclined cylindrical pan, bottom and walls rotating as one body, carries the entire charge into the tool.
02
Tool rotates the other
An eccentrically mounted mixing tool spins independently, against the pan motion, at speeds up to 40 m/s.
03
Independent drives
Pan speed and tool speed are decoupled. Energy input becomes a parameter, not a consequence of throughput.
04
Variable energy
Gentle blending and high-shear dispersion happen on the same machine. The recipe sets the regime.
S / SIZE TABLE
From 0.1 litre
to 12,000 litre.
The same drawing, scaled. Three classes cover the full range from a benchtop laboratory cabinet to a production cell.

Large scale
V / VARIANTS
Five housings.
One geometry.
The pan, tool and drive geometry stays constant across the five variants. The housing changes for the process at hand.
V01
Standard
Fixed pan, top access, the reference geometry for most processes.
V02
Hinged
Hinged cover for fast cleaning between recipes and visual inspection.
V03
Tilting
Pan tilts 30° to discharge by gravity. No scraper, no residue.
V04
MixSolver
High shear dissolving variant for liquid binders, slurries and pastes.
V05
Evactherm
Sealed vacuum housing for evacuation, evaporative cooling and inert atmosphere processing.
PR / PROCESSES
Seven processes.
One machine.
Mixing, granulating, kneading, dispersing, coating, drying and vacuum operation are all carried out on the same intensive mixer. Only the recipe changes.
MIXING
Homogenisation across density and particle size
GRANULATING
Wet and dry granule build up to controlled size
KNEADING
Plastic and viscous masses, controlled torque
DISPERSING
High shear breakup of agglomerates
COATING
Surface treatment and binder distribution
DRYING
Combined mixing and drying under vacuum
VACUUM
Down to 10 mbar, inert or reactive atmospheres
A / APPLICATIONS
Fifteen industries.
One mixer drawing.
The intensive mixer is at work across the full Eirich industry list. Every application has been measured at Hardheim before it shipped.
