Automatic Fluidized Bed Cooler for Foundry Sand Lines

Ultra-Efficient Cooling – Outlet Sand ≤50°C
Capacity: 30–150 t/h; outlet temperature stably controlled at 40–50°C, eliminating moisture loss, mold strength drop, and metal penetration defects caused by hot sand.

Low Energy Consumption – Cost Efficient
Uses only ambient air—no chillers or chilled water required. Specific energy consumption ≤0.8 kWh/t·°C, saving >30% vs. rotary coolers.

Minimal Maintenance – No Moving Parts in Bed
No rotating, vibrating, or agitating mechanisms inside the bed—only blower and discharge valve require service. Downtime reduced by 50%.

Modular & Scalable
Standard modules (1000–2500 mm wide) can be paralleled for capacities up to 300 t/h. Integrates seamlessly with reclaimers and mullers.

Eco-Compliant & Smart-Controlled
Fully enclosed with dust extraction ports (DN300–DN500). PLC manages airflow, level, and discharge—interlocked with central sand system control.

Automotive Engine Lines: Green sand cooled to ≤45°C for stable high-pressure molding
Ductile Iron Pipe Plants: Furan sand cooling prevents premature resin cure
Steel Foundries: Sodium silicate sand temperature control improves shakeout & reclamation
Smart Foundry Pilots: Core unit in "constant-temperature sand" closed-loop systems
