A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The typical aggregate outlet temperature is 150-180°C, as listed in the reference parameters. However, the exact temperature depends on the specific model, aggregate moisture content, and plant requirements. Always verify with the manufacturer.
Common materials include carbon steel (e.g., Q235B per GB/T 700) for the drum shell, heat-resistant steel for high-temperature zones, and refractory lining for insulation. The shell thickness typically ranges from 10-20 mm. Confirm material grades with the supplier.
The drum rotates at 3-8 rpm, and internal flights lift the aggregates, causing them to cascade through the hot gas stream. This ensures uniform exposure to heat and efficient moisture removal. The rotation speed can be adjusted for optimal material flow.
Key parameters include drum diameter (1.5-3.0 m), length (6-12 m), production capacity (80-400 t/h), drive power (15-45 kW), fuel consumption (5-12 kg/t), and weight (15-45 t). These are reference ranges; verify with the manufacturer for your specific application.
