Mixing emulsifiers are classified based on their structure, working principle, and application scenarios. Common types include:
Rotor-Stator Emulsifiers: The most widely used type, consisting of a rotating rotor and a fixed stator with precision slots. They generate high shear force and are suitable for batch or continuous production (e.g., inline rotor-stator emulsifiers for continuous processing).
High-Pressure Homogenizers: Force materials through a narrow gap at extremely high pressure (typically 100–1500 bar), using shear, impact, and cavitation effects to achieve emulsification. Ideal for producing fine emulsions (nanoscale) in industries like pharmaceuticals and food.
Colloid Mills: Utilize a rotating cone or disk and a fixed cone/disk with a small gap. Materials are crushed and sheared as they pass through the gap, suitable for high-viscosity materials (e.g., adhesives, cosmetics).
Ultrasonic Emulsifiers: Use high-frequency ultrasonic waves to create cavitation in liquids, breaking down droplets. Suitable for lab-scale or small-batch production of fine emulsions.
