1. High sieving accuracy: Using air flow as the driving force, it can fully disperse the materials on the sieve surface, avoiding agglomeration and blockage. It can precisely separate particles of different sizes, with a sieving accuracy up to 500 mesh or even higher, and has a remarkable sieving effect on fine materials.
2. High efficiency: The rapid flow of air can drive a large amount of materials to pass through the sieve mesh quickly, with strong processing capacity.
3. Minimal material damage:Air classification is a relatively gentle method. Compared with mechanical sieving, the impact force and friction force of air flow on materials are small, which can reduce material breakage and wear. It is suitable for brittle materials that are prone to breakage and wear or materials with high requirements for particle integrity.
4. Clean and environmentally friendly: The fully enclosed structure design effectively prevents material dust from flying, reduces dust pollution, improves the working environment, and meets environmental protection requirements. The air flow circulation system can filter and purify the air flow, making the discharged gas meet environmental protection standards. At the same time, it can recover the material particles in the air flow, reducing material waste.

Precautions:
1. Equipment Cleaning: Clean the test sieves, sieve trays, and collection bottles promptly.
2. Inspection of Key Components: Regularly inspect the air nozzles and pneumatic components, and replace damaged parts promptly.
3. Storage Conditions: Store in a dry and clean environment.
4. Selection of Appropriate Test Sieves: Choose test sieves based on the particle size of the sample.
5. Timely Cleaning of Samples: Avoid sample accumulation to prevent impacts on pressure.
6. Data Management: Record the sieving results and back up the data regularly.
