Fluid Division Mixing (FDM)
TECHNOLOGY - High Shear


FDM is a rotor-stator mixing technology that can be used in two distinct modes to achieve different mixing effects, depending on the type of material being mixed and the speed of the mixer.
High Shear Mode Low Shear Mode




Custom-designed for each application

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
