Air-Cooled Water-Cooled Drum Cooler Machine

Air-Cooled Water-Cooled Drum Cooler Machine
The Foundry Sand Drum Cooler by Guoning is a high-performance cooling
solution designed for sand treatment in lost foam casting and other foundry
processes. This equipment rapidly cools hot recycled sand to a controlled
temperature, ensuring consistent sand quality for reuse. With a combination
of water cooling and air cooling, and automatic sand flow and temperature
regulation via PLC, it delivers stable performance while minimizing manual
operation.
This drum cooler is ideal for foundries seeking to enhance production
efficiency, reduce energy consumption, and maintain the quality of recycled
sand throughout the casting process.

Working Principle
Hot recycled sand enters the drum from the feeding hopper. As the drum rotates,
the spiral lines lift and transport the sand, allowing air and water to
efficiently absorb heat. An axial flow fan directs airflow from the sand outlet
into the drum, guiding heat and dust toward the exhaust. The hot air passes
through a cyclone dust collector, which removes dust before clean air is
discharged. Water pipes spray both the inside and outside of the drum,
providing rapid cooling and ensuring sand reaches the desired temperature
efficiently. A blocking wheel system prevents excessive axial force, ensuring
safe and stable operation.
