High Speed Disperser Working Principle | JCT Machinery

high speed disperser disc
The main working part of high speed disperser is the impeller. The most commonly used one is the sawtooth disc impeller. The impeller is driven by a high-speed rotating dispersion shaft, and the rotation direction is clockwise.
high speed disperser principle
The high-speed rotation of the impeller causes the continuous phase in the mixing tank to present a rolling circulation and generate a large vortex, which is located in a turbulent area of the continuous phase. In this area, the dispersed phase particles are subjected to strong shear and impact, so that they are quickly dispersed into the continuous phase. Outside this area, two upper and lower streams are formed, so that the continuous phase is fully circulated and turned. If the impeller is in a lamminar state, the interaction between the liquid layers of different speeds is called the effect of viscosity shear force, which can achieve a good dispersion effect.
high speed disperser
High speed disperser has both mixing and dispersing effects. In the initial stage of the operation of high speed disperser, the dispersed phase is still piled on the continuous phase. At this time, low-speed mixing is used to prevent dust, and then the speed is increased to increase the dispersion capacity. The circumferential speed of the impeller should not be too high, otherwise liquid splashing will occur, exposing the disc impeller too much and causing air mixing. It may destroy the laminar flow state formed under the impeller, reduce the dispersion efficiency and increase power consumption unnecessarily. The maximum circumferential speed is generally about 25-30m/s.


Principles For Selecting High Speed Disperser

  • 1

  • It is necessary to clearly understand the effects and purposes of using the high speed disperser.

  • 2

  • It is necessary to have a detailed understanding of the properties of the materials.

  • 3

  • Select the agitator of the high speed disperser based on the materials.

  • 4

  • It is necessary to determine the operating parameters and structural design of the disperser.

  • 5

  • Consider the installation cost while considering the equipment cost of high speed disperser.
