In the world of particle processing, achieving consistent particle size is key to product performance, efficiency, and customer satisfaction. Air classification offers a precise, energy-efficient way to separate materials into fine and coarse fractions—without the need for mechanical sieving or screens. At AVEKA, our air classification systems allow us to deliver the exact particle size distribution our customers need for applications across industries like food, chemical, and specialty materials.
What Is Air Classification?
Air classification is a dry separation process that uses air flow and centrifugal forces to sort particles based on mass. As material enters the classifier, an air stream carries the particles into a rotating wheel. Fine particles (lower mass) are drawn through the classifier and collected, while coarse particles (higher mass) are rejected and discharged for further processing or recycling.
This method offers a clean, precise, and scalable solution for achieving narrow particle size distributions—especially for materials that are sensitive to heat or moisture.
Advantages of Air Classification
- High Precision:
Air classifiers can separate materials with extremely tight particle size tolerances, often down to a few microns. - Gentle Processing:
Because it’s a dry, minimal-contact method, air classification minimizes wear contamination for abrasives and degradation of fragile or heat-sensitive materials. - Cost-Effective:
The process can be more efficient than other separation techniques, reducing waste and energy use. - Customizable for Your Material:
Air classification can be tailored to different materials—ranging from minerals to food powders—to achieve the desired product consistency.
Applications at AVEKA
At AVEKA, we use air classification for a wide range of materials, including:
- Industrial minerals and ceramics that require precise control for performance and finish
- Polymers and specialty chemicals where particle size influences additive manufacturing properties, reaction rates, or dispersion
Our engineers work closely with customers to optimize parameters like air flow, rotor speed, and feed rate, ensuring consistent and reproducible results.
Integrated Processing Solutions
Air classification is often one part of a broader particle processing solution. At AVEKA, we combine air classification with milling, blending, and drying to deliver turnkey manufacturing support—from R&D-scale trials to full production. This integrated approach helps customers streamline their supply chain and improve product performance.
