Working Principle and Equipment type features
The classifier and cyclone separator, dust collector and induced draft fan form a classifying system. Under the action of fan suction, the material is moved from the lower inlet of the classifier to the classifying zone with the ascending airflow. Under the strong centrifugal force generated by the high-speed rotating turbine, the materials are separated and the fine particles which meet size requirements through the classifier impeller gap into the cyclone separator or the dust collector, the coarse particles entrained part of the fine particles collided with the wall and the velocity disappeared, descending along the cylinder wall to the secondary air outlet, and the coarse and fine particles were separated by the strong washing action of the secondary air. The fine particles rise to the classification zone for secondary classifying, and the coarse particles are lowered to the discharge port for discharging.
Single Classifying Wheel Working Principle
- 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.
