The MD coal mill dynamic air classifier is a high-performance air classifier integrating coarse powder separation and horizontal vortex air classification. It is mainly used in air-swept coal mill systems and can also be used for the classification of materials such as fly ash. Its classification principle utilizes vertical guide vanes and a straight-cage rotor, representing the most advanced classification structure available today, achieving a classification efficiency of over 90%. An internal vortex rectifier ensures that the airflow within the rotor alternates between rising and rotating motions, significantly reducing airflow resistance within the air classifier, saving drive power, and reducing wear.

Performance Features:

1. Classification principle: Utilizing vertical guide vanes and a straight-cage rotor, representing the most advanced classification structure available today, achieving a classification efficiency of over 90%.

2. Internal vortex rectifier: The airflow within the rotor alternates between rising and rotating motions, significantly reducing airflow resistance within the air classifier, saving drive power, and reducing wear.

3. The air classifier's main shaft uses stepless frequency conversion speed regulation, allowing for convenient fineness adjustment. It is sensitive and reliable, with a wide adjustment range of 15-80µm.

4. The easily worn parts of the air classifier, such as the feeding disc, cyclone separator, guide vanes, and rotor grading blades, are all made of wear-resistant materials or treated with anti-wear processes, resulting in extremely low wear rates and effectively extending their service life.

5. The entire machine operates under positive pressure with internal airflow circulation. It is equipped with mechanical lifting and distribution equipment, resulting in a simple system structure and stable and reliable operation.
