Classification Equipment
Airflow Classifier
The airflow classifier sorts dry particles by size using aerodynamic principles. Feed enters the machine, and internal forces separate fine product from coarse rejects. This dry process is well suited to minerals that are moisture-sensitive or need additive-free separation.
Technical parameters
Placed downstream of a mill, the classifier operates in closed circuit. Coarse particles return to regrind, while fines go to downstream processing. This layout stabilises mill loading and narrows the product particle size distribution.
The eight models cover a range of production capacities and product finenesses. As model size increases, installed power and throughput capability rise. Classification efficiency varies by model and application, so the table helps engineers match a unit to their required cut size and throughput target.
| Model | Production Capacity (t/h) | Product Fineness (μm) | Classification Efficiency (%) | Main Machine Efficiency (kW) | Installed Power (kW) |
|---|---|---|---|---|---|
| AF050 | 0.1-0.5 | 2-100 | 70-85 | 5.5 | 30 |
| AF100 | 0.5-1.0 | 2-100 | 70-85 | 11 | 45 |
| AF200 | 1.0-3.0 | 2-100 | 70-85 | 22 | 70 |
| AF400 | 2.0-8.0 | 2-100 | 70-85 | 37 | 95 |
| AF600 | 5.0-15 | 2-100 | 70-85 | 45 | 120 |
| AF800 | 10-25 | 2-100 | 70-85 | 55 | 200 |
| AF1000 | 20-50 | 2-100 | 70-85 | 75 | 250 |
| AF1200 | 50-100 | 2-100 | 70-85 | 110 | 360 |
Standard-model catalogue figures. Actual capacity, power draw and wear life shift with ore properties, feed gradation and circuit conditions. Use them to shortlist, then confirm the duty by testwork, flowsheet calculation and a written confirmation from the manufacturer.
What decides the selection
Before selecting an airflow classifier model, the project team should define the ore type, target product fineness, and required throughput. Moisture sensitivity and the acceptable range of cut sizes also influence the choice. Working with the supplier to match these process requirements to the model range ensures the classifier meets circuit performance goals.
