Closed-loop Airflow Classifier
Closed-loop Airflow Classifier
【Product Overview】：The closed-loop airflow classifier is a device that uses airflow to finely classify powder materials, with its core feature being the recycling of airflow to improve energy efficiency and classification accuracy.
Product Introduction
Principle Introduction
The closed-loop airflow classifier is a piece of equipment used for fine classification of powder materials through airflow. Its core feature is the recirculation of airflow, which improves both energy efficiency and classification precision.
The working principle of the classifier is that, under the combined effects of centrifugal force and airflow drag within the classifier, materials are separated according to particle size.
Equipment Advantages
- The classifier uses independent horizontal impellers for classification, achieving a narrow particle size distribution.
- It features high capacity, low energy consumption, high classification efficiency, and a rational structure.
- All impeller classifiers at each stage are equipped with electronically controlled variable-frequency stepless speed drives, which enhance the stability of the machine’s overall negative pressure.
