What is a disperser?

The disperser is one kind of mixer in a broad sense. The linear velocity, produced by dispersing disc’s high-speed rotation, generates the strong hydraulic shear, centrifugal extrusion, high-speed cutting and collision between the material and dispersing disc to realize the material’s complete dispersing, emulsifying, homogenizing, smashing, suspending and mixing.So this kind of mixer is also called disperser.
Disperser can be divided into lift-type disperser and kettle-type disperser. Lift-type disperser can be divided into hydraulic lifting disperser, air-operated lifting disperser, manual lifting disperser, etc.
Performance feature:
1 The strong centrifugal force throws the material from radial direction to the narrow and precise gap between the stator and rotor. Then the material is dispersed preliminary by the total effect force of centrifugal extrusion, liquid layer friction, hydraulic strike and so on.
2 The high-speed rotating rotor generates the linear velocity of at least 15m/s. The material is dispersed and crushed by the effect of hydraulic shear, liquid layer friction, tear and collision, etc. And then the material is ejected with high speed through stator slot.
3 Material is shoot out from radial direction at a high speed continually, then change the direction under the resistance caused by material itself and tank wall and form two strong stirring turbulent flow (upper and lower) at the same time under the Upper and lower axial suction force generated in the rotor. After several times of circulation, the material is dispersed completely at last.

Model selection remarks:
1. Firstly get clear purposes of using the equipment.
2. Secondly know in detail the material’s characteristics.
3. The agitator’s selection depends on the material’s characteristics.
4. Confirm the operating parameters and structural design of the disperser.
5. Think about the installation cost while considering the disperser’s price.
