Characteristics:
- Mixer run at high speeds
(3000rpm+)
- Low-medium viscosities
(<100000cP)
- Batch or inline operation
possible
- Delivery pump required for
>30000cP
(for inline applications)
Mixing Principle:
turbulent
hydraulic shear
Used for:
- Rapidly dispersing powder in
liquids
- De-agglomerating solids in
liquids
- Wet milling
- Emulsification
- General high shear mixing duties
Example Applications:
- Dispersing food gums in water
- De-agglomerating solids in
liquids
- Reducing particle size in
bentonite slurry
- Wet milling of paint pigments
- Printer ink presscake dispersions
- Pre-mixing solutions for
IPM
machines

Characteristics:
- Mixer run at low speeds (<500rpm)
- Medium-high viscosities
(>50000cP)
- Inline operation only
- Delivery pump always required
(an extruder can act as the pump)
Mixing Principle:
inter-cavity
transfer
Used for:
- Gentle blending of
shear-sensitive fluids
- Blending of multiple input
streams
- Post-mixing of plastic melts
- Post-extruder conditioning of
rubbers
- Replacing static mixers at high
viscosity
Example Applications:
- Blending colours into cellulose
acetate
- Improving post-extrusion thermal
homogeneity in rubber materials
- Adding colours to plastic
meltstreams
- Blending of dissimilar rubbers
- Blending foaming agents into
rubber
- Eliminating post-extrusion
"nerve"
in rubber materials
