Variable Frequency Motor Drive Air Classifier Sorting Machine for Construction Waste Line

1. Fully Closed System, Negative Pressure Dust Control Circulating duct air volume exceeds intake, keeping the chamber under slight negative pressure so dust cannot escape.

2. Aerodynamic Light/Heavy Separation Controlled airflow carries paper, plastic film and bags horizontally into the settling chamber, while heavy components fall away by gravity.

3. Independent VFD Control of Air and Belt Speed Fan and conveyor are driven by separate variable frequency motors, so air volume and belt speed can be tuned independently to suit different material

4. Compact Footprint The horizontal layout keeps the unit low and compact, fitting into existing lines and saving floor space

5. High Capacity with Modest Power FKW1000 handles 15-25 m3/h at 37.5 kW, FKW1600 handles 50-80 m3/h at 88.2 kW

6. Reliable Tier-1 Components All motors, reducers and bearings are sourced from tier-1 brands, so the machine runs continuously in dusty,

7. Low Maintenance Demand No consumable filters or water treatment. Routine inspection every 3-6 months plus annual belt and fan checks is enough to keep the unit in service.

8. Ready to Integrate into Complete Lines Designed to sit alongside crushers, screens, eddy current separators and magnetic separators, forming a full C&D waste or material recovery line from a single
