What Is The Working Principle Of Air Classifier?
Under the action of the fan, the material moves to the classification area at a high speed from the lower inlet of the classifier with the updraft. Under the action of the strong centrifugal force generated by the high-speed rotating classification turbine, the material is separated, and the fine particles meeting the particle size requirements enter the cyclone separator or dust collector through the blade gap of the classification wheel for collection. The velocity of some fine particles entrained by coarse particles disappears after hitting the wall, and then decreases to the secondary air outlet along the wall of the cylinder. Through the strong washing effect of the secondary air, the coarse and fine particles are separated, the fine particles rise to the secondary classification in the classification area, and the coarse particles drop to the discharge port for discharge.
Horizontal Air Classifier(Single Classifying Wheel)
- A horizontal mounted staged rotor, linear speed can reach 100m/s;
- The rotor speed can be adjusted by frequency conversion, and the force distribution can be adjusted flexibly;
- Suitable for precise classifying of dry micron material;
- Available D50:1.5-25μm.
Horizontal Air Classifier(Multiple Classifying Wheel)
- The rotor diameter is 315mm-630mm, and 2-6 rotors, which is used for ultra-fine powder classification;
- The classifying wheel increases the classifying space on the top of silo;
- Inverter control, adjustable speed;
- Higher output than single rotor.
