High Speed Disperser Working Principle
  • 1. High Speed Rotating Blade or Disc

  • High speed dispersers usually contain a rotating spindle with blades or discs mounted on it. These blades or discs are designed to produce intense shearing forces by rotating at high speeds.

  • 2. Liquid Circulation

  • When high speed disperser is started, the blades or discs begin to rotate at high speed. This causes the liquid tto form a vortex flow in the mixing chamber, causing the material to be continuously sucked in and discharged.

  • 3. Generation of Shear Force

  • High speed movement of the blade or disc causes strong relative movement between materials. The shear force generated by this relative motion breaks down, shears and stirs the materials to achieve dispersion and suspension.

  • 4. Suspension and Homogenization

  • The shearing action of the blade or disc causes the particles, powder or suspended solids in the material to be dispersed and evenly suspended in the liquid. This ensures the uniformity of the entire material system.

  • 5. Adjustable Speed and Processing Parameters

  • High speed disperser usually has an adjustable speed function, and the operator can adjust the rotation speed according to the requirements of the material being processed . Other processing parameters, such as stirring time and temperature, can also be adjusted.

  • 6. Temperature Control

  • In some high speed dispersers, the temperature of the stirring chamber can be controlled by heating or cooling equipment. This is important for applications that handle heat-sensitive materials or require specific temperature conditions.

Causes of Turbulent Flow in High Speed Disperser
  • 1. High Speed Rotation of Blades or Discs
    The blades or discs inside the high speed disperser rotate at high speed, producing strong cutting and stirring effects. This high speed rotation causes the liquid to move and flow rapidly, leading to the formation of turbulence.
  • 2. Strong Shear Force
    The movement of the blade or disc causes the relative movement of the various layers of fluid in the liquid, resulting in strong shear force. This shear force causes irregular movement of the fluid and promotes turbulence.
  • 3. Liquid Instability
    The operation of high speed dispersers can cause liquid instability, especially during the suction and discharge of liquid in the mixing chamber. This instability further promotes turbulence.
  • 4. Vortex Flow Inside the Liquid
    The rotation of the blade or disc creates a vortex flow of the liquid inside. These vortices are constantly forming and changing, creating turbulent structures.
