Looking for reliable China suppliers? Our factory provides the high precision Double Disc Cooler, a high efficiency sand conditioning system that ensures optimal temperature and moisture for superior molding sand quality with low energy consumption.
The Double Disc Cooler is a high-precision sand conditioning system specifically engineered for the demanding requirements of ferrous metal casting. By integrating advanced temperature and humidity sensors with a dynamic agitation system, this equipment ensures that reclaimed sand reaches the optimal thermal and moisture state before returning to the production line, significantly enhancing mold stability and casting quality.
Utilizing a sophisticated feedback loop, the system automatically adjusts water spray volumes and sand door openings based on real-time data. This precise control prevents overheating and moisture fluctuations, while the integrated dust removal system ensures a clean working environment. The result is a highly efficient, automated process that guarantees consistent sand properties regardless of seasonal ambient temperature changes.

| Metric | Manual Cooling | Double Disc Automated |
|---|---|---|
| Temp Stability | High Variance | Precise (±10°C of Amb) |
| Moisture Error | ±1.0% to 2.0% | ±0.3% Precision |
| Labor Cost | High (Manual Adjust) | Low (Fully Automated) |
| Sand Waste | Moderate (Over-wetting) | Minimal (Optimized Spray) |
| Casting Yield | Standard | Increased (Better Consistency) |
The system uses a dynamic formula (Ambient Temperature + 10°C) and automatic water spray adjustments to ensure sand remains below the critical threshold even in hot climates.
Horizontal and vertical agitation prevents "dead zones" in the cooler, ensuring every sand grain is exposed to cooling air and water for perfectly uniform properties.
Integrated moisture sensors provide real-time feedback to the water adding system, which adjusts the spray volume to keep moisture strictly between 1.7% and 2.3%.
Yes, the pre-mixing function is designed to ensure that bentonite is well expanded, which is critical for achieving the required bonding strength in the molding process.
The system continuously monitors the working current of the mixing motor. If the load increases, it automatically adjusts the sand door opening to stabilize the sand volume.
Hot vapor generated during the evaporative cooling process is quickly pumped out and routed into a specialized dust removal system to maintain air quality.
