What is Air Classifier Mill

By: Powder Mill 2025-09-01

Air classifier mill (ACM) is a versatile industrial machine used for size reduction (grinding) and air classification of a wide range of materials. The air classifier mill feature is that it combines a mechanical impact mill with an integrated dynamic air classifier, all in a single unit. High-speed, precision grinder that can also sort the particles it produces, ensuring a consistently fine and controlled product size.

Air Classifier Mill

Working Principle of Air Classifier Mill :

1. Feeding and Grinding: Material is fed into the grinding chamber, where a high-speed rotor equipped with hammers or blades pulverizes the particles through repeated impacts and collisions. A constant airflow is drawn into the mill, which helps to convey the material and cool the grinding process, making it suitable for heat-sensitive materials.

2. Classification: The ground particles are carried by the airflow into the classification zone, where a rotating classifier wheel separates them. The classifier wheel creates a centrifugal force that acts against the air drag force.

3. Recirculation: This continuous cycle of grinding and classifying ensures that only particles that meet the desired size specifications are discharged. The speed of the classifier wheel can be adjusted to precisely control the final particle size and distribution.

Advantages of Air Classifier Mill:

1. Precise Particle Size Control: The independent variable speed of the classifier wheel allows for extremely tight control over the final product’s top particle size .

2. Narrow Particle Size Distribution: Produces a very uniform product with minimal fines or coarse tails, which is critical in many industries.

3. Cool Operation: The large volume of air moving through the mill acts as a coolant, making it ideal for heat-sensitive materials.

4. Dust-Free Operation: The entire process is enclosed, making it a clean system with minimal dust generation.

5. High Efficiency: The closed-loop system of re-grinding coarse particles leads to high energy efficiency and high output.

6. Versatility: Can handle a wide range of materials, from soft and fibrous to medium-hard.

Application Industry:

1. Chemicals: Pigments, dyes, resins, pesticides, fertilizers.

2. Pharmaceuticals: Active Pharmaceutical Ingredients (APIs), excipients.

3. Food: Spices, sugars, starches, gums, flour, colorants.

4. Minerals: Talc, gypsum, calcium carbonate, graphite.

5. Cosmetics: Mica, titanium dioxide, powders.
