The VRS
Rotor Stator Mixer

The Variable-Speed Rotor Stator is designed for high-speed dispersing, mixing, size reduction and deagglomerating at significant process savings. It creates mechanical shear by continuously drawing product components into the rotor and expelling them radially through the precision milled openings in the stator. Alternative options include the VHS High-Speed Disperser and ILD Inline Disperser.

  • Disperse, emulsify, homogenize, dissolve, mill, mix and blend
  • Improves high-speed dispersion of paints, resins, inks, coatings, adhesives and more
  • Ultra-shear design achieves dispersion at a much faster rate than a standard high-shear blade
  • Eliminates additional processes such as grinding, milling or additional mixing
  • Reduces the toughest agglomerates in size, blends them with liquid additives, and wets them out to create a consistent dispersion

Description

How Does a Rotor Stator Work?

A rotor stator is a highly efficient device used for high-speed dispersing, mixing, size reduction, and deagglomerating. It works by utilizing a rotor that spins within a stationary slotted stator at very high speeds. This setup acts like a centrifugal pump, drawing the product into the rotor and then expelling it against the slots in the stator. The high radial velocity and impact force generated cause the particles to break down as they hit the slots and surfaces of the stator. This repeated shearing process ensures maximum dispersion as the product continuously cycles back into the rotor.

The ultra-shear design of the rotor stator achieves dispersion at a much faster rate compared to standard high-shear blades, reducing the need for additional processes like grinding or milling and saving up to 90% of production time.
