The S56II Series Fluidized Bed Cooler is a high-efficiency sand cooling system engineered for foundries to rapidly and uniformly cool hot reclaimed sand—from 150–400°C down to ≤50°C—meeting the stringent temperature requirements of high-pressure molding lines. Based on fluidization heat transfer, it injects ambient air through a perforated plenum plate, causing sand particles to enter a suspended "boiling" state for maximum sand-air contact. This achieves 2–3× higher heat exchange efficiency than conventional vibratory or rotary coolers—making it a critical component in green, smart, closed-loop sand reclamation systems.
Working Principle
Infeed: Hot sand (150–400°C) is evenly fed onto the cooler bed.
Fluidized Cooling: A blower forces air through micro-perforated plates, fluidizing the sand layer—maximizing heat transfer via convection and conduction.
Residence Time Control: Internal overflow weirs or baffles create staged zones, ensuring 3–8 minutes of uniform cooling.
Dust-Laden Air Exhaust: Hot, dusty air exits from the top and passes through cyclone + baghouse—emissions ≤10 mg/m³.
Discharge: Cooled sand (≤50°C) is continuously discharged via bottom rotary valve to muller or reclaimer.
Key Technical Features
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.
