What is a high-speed shear dispersion emulsifier, and how does it work?

What is a high-speed shear dispersion emulsifier, and how does it work?

 
A high-speed shear dispersion emulsifier is a mechanical device that integrates dispersion, emulsification, and homogenization functions, primarily used to process multi-phase materials (solid-liquid, liquid-liquid). Its core component is a shear head (rotor-stator assembly), which operates at high rotational speeds (typically 3,000-15,000 rpm) to create intense shear, cavitation, and turbulent forces.
 
The working principle involves three key stages:
 
  • Shearing: The rotor rotates at high speed, drawing materials into the gap between the rotor and stator (usually 0.1-0.5 mm). The velocity difference between the rotating rotor and fixed stator generates strong shear forces that break down large particles and oil droplets into smaller sizes.
  • Cavitation: The rapid pressure changes caused by high-speed rotation form micro-bubbles in the material. These bubbles implode instantly, releasing enormous energy to further disrupt particle aggregates and promote phase fusion.
  • Dispersion: Turbulent flow generated by the shear head circulates materials continuously, ensuring uniform distribution of dispersed phases throughout the system, avoiding re-agglomeration of particles, and achieving stable emulsification or dispersion effects.
 
Unlike conventional mixers, high-speed shear emulsifiers rely on mechanical shear rather than simple stirring, enabling finer particle size control and more stable phase integration.
