Product Uses

1.  Mineral Industry

Air flow classifiers are widely used in mineral powder processing, offering precise and adjustable particle-size separation for gold, copper, iron, chrome, calcium carbonate, talc, kaolin, quartz, bentonite, clay, and mica.  By utilizing high-speed airflow and centrifugal force, the classifier can efficiently separate fine and ultrafine mineral powders, improve product purity, and enhance downstream grinding efficiency.  It is also ideal for sand sorting and complete mineral processing lines requiring stable, high-throughput classification.

2.  Chemical Industry

In the chemical sector, air flow classifiers provide accurate separation for pigments, dyes, coating materials, flame retardants, catalysts, polymer powders, and various additives.  The system prevents contamination, avoids overheating, and maintains particle uniformity—crucial for high-performance chemicals.  It also supports plastic–metal separation and battery-material classification such as lithium manganate and other cathode powders, ensuring consistent quality required for modern chemical and energy-storage applications.

3.  Pharmaceutical Industry

For pharmaceutical production, air flow classifiers enable gentle, precision classification of APIs, heat-sensitive powders, and herbal granules.  The low-temperature airflow process prevents degradation of active ingredients while achieving narrow particle-size distribution.  This ensures improved bioavailability, better tablet pressing performance, and compliance with strict pharmaceutical standards.  The system is suitable for clean-room environments and supports continuous production with stable, contamination-free operation.

4.  Food & Spice Industry

Air flow classifiers are ideal for processing food powders such as chili powder, pepper powder, tea leaf powder, sugar, and food additives.  The non-contact airflow separation maintains flavor, aroma, and color while achieving consistent fine powder quality.  It is particularly useful for high-value spices and heat-sensitive food ingredients, ensuring uniform particle sizes for instant beverages, seasonings, bakery mixes, and powdered extracts.  The design supports hygienic production and easy cleaning.

5.  New Energy & High-Tech Materials

In the new-energy and electronic-material sectors, air flow classifiers are used for lithium battery materials, electronic ceramics, nano powders, and micron-scale functional materials.  The system provides ultra-precise separation required for battery cathode/anode performance, dielectric stability, and electronic component reliability.  With a controllable cut size and low contamination rate, it ensures high purity and consistency—critical for advanced materials manufacturing and high-tech applications.

6.  Recycling & Environmental Industry

Air flow classifiers play an important role in modern recycling systems, enabling efficient separation of plastic–metal mixtures, municipal solid waste (MSW) fractions, and regenerated powders.  By using aerodynamic principles, the classifier can sort lightweight and heavy particles accurately without water or chemicals.  This improves recycling efficiency, reduces processing costs, and supports eco-friendly waste management.  It is also suitable for closed-loop powder recycling in industrial production lines.

Product Operate Guide

To operate the Air Flow Classifier, first ensure all pipes, valves, and the dust-collection system are properly connected and sealed. Start the main fan and classifier rotor to let the airflow stabilize. Feed dry and pre-processed material evenly into the inlet to achieve accurate classification. Adjust rotor speed and airflow to control particle size. Monitor pressure and discharge ports to ensure smooth operation. After finishing, stop feeding, let the system run empty for a few seconds, then power off and clean all components for the next batch.
