VMS - Vertical MaxShear Rotor/Stator Mixer

Shorter mixing cycles, more uniform blending


Featuring a precision high-speed rotor, which creates a vigorous pumping action as it draws liquid into the stator inlet. Liquid is discharged at high velocity through machined slots in the stator. This results in a powerful combination of mechanical and hydraulic shear. Certain processes such as emulsification or dispersing pigments and other solid particulate into a liquid medium requiring high shearing action.

  • Shorter mixing cycles
  • More uniform
  • Faster wetting and dissolving of hard to wet powders
  • Finer particle size of suspended solids
  • Smaller emulsion droplet size
  • Improved premixes to increase efficiency of downstream grinding devices (such as media mills)


  • Close tolerance rotor/stator mechanism provides an effective combination of both "high flow" and "high shear".
  • Large rotor blade surface area and shearing edge for high pumping action and intensive mechanical shearing at the rotor/stator interface.
  • Large internal stator shearing surface area with fine slot opening for efficient homogenizing, emulsification, "grinding" and particle size reduction capacity.
  • All 316 stainless steel wetted components with Bronze shaft bearing as standards.
Vertical Max-Shear Disperser/Emulsifier





The Vertical Max Shear Rotor/Stator Mixer - for emulsifying or dispersing pigments and other solid particles in a liquid medium, which require a high shearing action.


NETZSCH-Feinmahltechnik GmbH offers mixing, kneading and dispersing machines for low- to high-viscosity products as well as a variety of wet-grinding units for reduction into the nanometer range, tailor-made for each application. When it comes to the processing of dry products by cutting, fine grinding or fine classification, you will find a wealth of experience and an equally varied program of fine-impact mills, classifier and jet mills as well as fine-cutting mills and high-performance fine classifiers.
