Product Description

Product Description of Water-Cooled Drum Cooler

The water-cooled drum cooler is a highly efficient and stable continuous indirect cooling device designed for high-temperature granular materials such as reclaimed sand, spent foundry sand, sinter, coke, and ceramsite. It is widely used in furan resin sand reclamation systems, resin sand production lines, foundries, metallurgical plants, and building material factories.
The equipment achieves uniform and rapid cooling of materials up to 800°C through heat exchange between internal circulating cooling water and material flowing inside the rotating drum. The discharge temperature is stably controlled at ≤60°C, meeting requirements for downstream conveying, storage, or sand mixing processes.
Equipped with fully enclosed structure, frequency control, and intelligent temperature regulation, the water-cooled drum offers high cooling efficiency, stable operation, easy maintenance, and energy savings—making it the ideal choice for high-temperature material cooling.

Working Principle

Hot material enters from the feed end of the drum. As the drum rotates slowly (1–5 rpm), the material moves forward along the inner wall in a spiral path. The drum has a double-shell structure with circulating cooling water flowing in the annular space. Heat is transferred indirectly through the drum wall. The heated water exits via the outlet, while the cooled material discharges at the end at the target temperature.

Key Features

High Cooling Efficiency & Precise Temperature Control
Optimized drum structure and water flow design ensure large heat transfer area and high efficiency. Discharge temperature is precisely controlled by adjusting water flow and drum speed.

Stable Operation & Long Service Life
Drum made of high-quality carbon or stainless steel, with optional wear-resistant liners. Support rollers and trunnions made of alloy steel for high load capacity, smooth operation, and durability.

Energy-Saving & Eco-Friendly, Low Operating Cost
Cooling water is recirculated with temperature monitoring and automatic makeup. Fully sealed design prevents dust emission—meets environmental standards.

High Automation Level
Equipped with frequency-controlled motor for stepless speed adjustment. Compatible with PLC for integrated control, fault alarms, and data logging.

Easy Maintenance & Access
Inspection doors, viewing windows, and cleaning ports allow easy access. Rational water circuit design resists scaling and clogging.

Modular Design, Flexible Configuration
Customizable drum length, diameter, and heat exchange area based on capacity (1–30 t/h), inlet temperature, and cooling requirements.
