The Annular cooler is a core piece of cooling equipment used in iron and steel sintering plants to reduce the temperature of hot material discharged from the sintering machine, typically from 700–1000°C to below 150°C, prior to downstream conveying, screening, and blast furnace charging.

ec@shyychina.comBased on a continuous annular traveling grate and optimized forced-air cooling, the annular cooler delivers uniform temperature reduction, stable material quality, and reliable operation under demanding process conditions.
This latest-generation Annular Cooler is specifically designed to minimize air leakage, improving thermal efficiency, supporting waste heat recovery, and reducing overall energy consumption.
Designed for reliability, efficiency, and low maintenance
Air leakage is one of the main limitations of conventional annular coolers, often caused by rapid degradation of rubber or asbestos seals under high-temperature and abrasive conditions.
This Annular Cooler replaces traditional sealing materials with flexible magnetic metallic sealing elements, supported by steel brush dynamic seals.
The sealing system automatically compensates for trolley deviation, structural deformation, and thermal expansion, maintaining stable sealing performance throughout operation.
Key advantages of this sealing concept include:
Significantly reduced air leakage
Elimination of seal burning and aging
Improved cooling and waste heat recovery efficiency
Reduced maintenance and longer service life
Customization Options
Configured to match your process
The Annular Cooler can be customized based on site conditions and process requirements, including:
