Triple Drum Dryer
Tongding’s triple cylinder rotary dryer is a core product integrating multiple invention patents. The three‑stage design ensures maximum heat exchange: the multi‑fold lifting plates inside the inner cylinder create a dense sand curtain for first‑stage drying; the serrated plates in the middle cylinder re‑scatter the material for second‑stage drying; the outer cylinder conveys and finishes the drying process.
Features:
- Capacity: 3-120 T/H (Customizable)
- Moisture Reduction: 25% → 3%
- Heat Source: Coal / Gas / Biomass
- Powdery materials: (1)Construction sands: river sand, sea sand, yellow sand, quartz sand, foundry sandplate sand, steel sand, fracturing sand; (2)Mineral & mining materials: tailings sand, copper ore sand, iron ore sand, coloredsand, fluorite powder, potash feldspar powder, sodium feldspar powder. (3)And other building materials sands and industrial bulk materials. Process: Drying → Dust Collection → Screening.

- Moisture Reduction: From ≤4% to below 0.5%
- High Inlet Temp: 700–750°C for efficient drying
- Low Power Consumption: Motor power ranges from 7.5 kW to 75 kW depending on model
Working Principle
Silica sand is fed into a rotary drum dryer via conveying equipment, where it is dried by high-temperature hot air generated from a heat source. In this process, air is filtered and dispersed, ensuring full heat exchange and rapid moisture evaporation.
Dust-laden exhaust gas is treated by a cyclone separator and dust collection system for emission compliance and dust recovery. The material moved is discharged with stable moisture content.
The dried sand is then conveyed to screening or storage systems, ensuring stable and efficient operation.
