Shear Dispersion Mixer

The shear dispersion mixer is primarily used to uniformly disperse solid particles or powders into a liquid medium, resulting in a homogeneous mixture. Based on the existing high-shear technology, a stirring device is added, typically in the form of a dual-shaft mixer or dual-shaft mixing kettle, to achieve improved shear dispersion. By utilizing rotating stirrers, dispersion discs, or cutting blades, the mixer generates intense shear and centrifugal forces, effectively cutting, breaking, and evenly dispersing particles within the liquid. This allows for efficient stirring, dispersion, homogenization, emulsification, and solid-liquid mixing, meeting various process requirements. Common application fields include pigments, dyes, coatings, inks, cosmetics, and fine chemicals.

 

The high-shear dispersion emulsifier utilizes mechanical forces to reduce the particle size of liquid-liquid and solid-liquid materials, ensuring one phase is uniformly distributed within another or multiple phases. This results in refined homogenization and effective emulsification, forming a stable emulsion. The emulsifier operates in a batch mode, featuring a novel bidirectional suction structure in its working head. It can be installed in three configurations: top-mounted, side-mounted, and bottom-mounted, allowing for combinations with various stirring devices for multifunctional use. The equipment is suitable for a wide range of viscosities and temperatures and is designed to meet the requirements for vacuum (100 mbar), explosion-proof (ATEX), and pressure (up to 10 bar) operating conditions.

Applicable Materials  Can be used for the mixing of solids and liquids, as well as liquid-liquid combinations to form solutions, colloids, suspensions, or emulsions. This includes a wide range of materials such as juices, soups, dairy products, tissue homogenates, cosmetics, surfactants, asphalt, emulsifiers, and oilfield chemicals, among others.

Working Principle

The main working components consist of a stator and rotor. Under the influence of the centrifugal and hydraulic forces generated by the rapid rotation of the rotor, the stator performs a series of actions including strong shear, centrifugal extrusion, impact rupture, liquid layer friction, and turbulence. This comprehensive effect allows various immiscible phases—solid, liquid, and gas—to be uniformly and finely dispersed and emulsified in an instant. Through a reciprocating cycle, the original product is transformed into a stable, high-quality end product.

Product Advantages

  • High Dispersion Efficiency and Quality
    The equipment can achieve a maximum rotational speed of 2930 rpm (with a high-power version at 1450 rpm) and a linear velocity exceeding 30 m/s, enabling rapid and uniform dispersion of powder materials into liquid media. The materials experience extremely high shear forces, resulting in uniform dispersion and excellent suspension effects. Different dispersion discs can be swapped out based on process requirements to achieve optimal dispersion results.
  • Strong Customization Capabilities
    Various non-standard products can be customized, including explosion-proof, closed, kettle-type, and lift-type models. Materials can also be tailored to specifications, including SS304, SS321, SS316L stainless steel, or titanium alloys.
  • High Processing Precision and Long Lifespan
    The rotor and stator are made from forged materials and processed using CNC machining centers, resulting in minimal gaps between the rotor and stator. This ensures excellent shear limits and high emulsification and dispersion efficiency. Additionally, nano-coatings can be applied to enhance the product's lifespan.
