The performance characteristics of the air classifier:
1. It is suitable for the fine classification of dry micron products. It can classify spherical, flake, and needle-shaped particles, and can also classify particles of different densities.
2. The particle size of the graded products can reach D97: 8～150 microns, the product particle size is steplessly adjustable, and the variety is extremely convenient to change.
3. The classification efficiency (extraction rate) is 60% to 90%, and the classification efficiency of materials with good fluidity is high, otherwise the efficiency is reduced.
4. The vertical grading turbine device is adopted, with low speed, wear resistance, and low system power configuration.
5. Multi-stage classifiers can be used in series to produce products with multiple particle sizes at the same time.
6. It can be used in series with ball mill, vibration mill, Raymond mill and other grinding equipment to form a closed loop.
7. The control system adopts program control, the running status is displayed in real time, and the operation is simple.
8. The system runs under negative pressure, and the dust emission does not exceed 40mg/m³, and the equipment noise is not higher than 75dB(A) through the use of silencer measures.
