The classifying wheel in air classifier mill (ACM) plays a crucial role in grinding process. The main function of classifying wheel in air classifier mill is to classify powder particles by fineness.
Specifically, the roles of classifying wheel in air classifier mill are mainly include the following aspects:
1. Preliminary grinding of material
When the material enters grinding chamber, classifying wheel begins to work. Through high-speed rotation, classifying wheel can generate strong centrifugal force, so that the material can achieve classification with centrifugal force. By adjusting the speed of classifying wheel and the size of classification aperture, the material can be classified into different grades to meet different needs in different application.
2. Airflow induction
Classifying wheel can adjust velocity and direction of airflow. Based on the structure and rotation, classifying wheel can adjust velocity and direction of airflow. When material passes through classifier impeller, the high-speed rotation of wheel disc would separate the powder and leave coarse particles on wheel disc for re-grinding.
3. Treatment of particles
As the particles rise to classifying wheel, they encounter two opposing forces: centrifugal force from classifying wheel and air resistance from airflow. The finer particles are less affected by centrifugal force and leave the mill with airflow, while the coarser particles are thrown back into the grinding chamber for further grinding.
4. Parameters adjusting
By adjusting speed of classifying wheel during operation can control particle size. Higher speed can increase centrifugal force and filter larger particles more effectively, while lower speed allow more fine particles to pass through. The structure of the wheel, including the height and number of impeller, can also affect airflow velocity and classification efficiency.

5. Continuous operation
The whole system operates in closed-loop state where coarse particles continue to recirculate until they reach desired fineness. Compared to system that requires separate classification step, the integration of grinding and classification within a single unit can enhance work efficiency and reduce operational costs.
Resumo
The classifying wheel in air classifier mill is vital to achieve precise particle size distribution, because it can balance centrifugal force and air resistance within dynamic airflow environment. This design has advantages of being able to handle materials efficiently and maintaining operational flexibility.
