Product Profile
The Multi-Tube Rotary Cooler stands as the premium industrial benchmark for applications demanding supreme thermal transfer rates and structural thermal recovery. Featuring a densely arranged internal multi-tube matrix scheme, it multiplies the operational contact area between hot solids and cooling walls, delivering rapid cooling curves and exceptional continuous mechanical uptime. It is highly optimized for high-temperature slag, granulated activated carbon, pure synthetic/natural graphite, and other crystalline powders requiring high purity and strict temperature thresholds.
Operating Principle
Upon entering the rotating drum, the hot materials are evenly distributed into separate pathways between or inside the densely configured tube bundle matrix. As the transmission subsystem drives the entire drum structure into rotation, internal helical flights propel the material smoothly along the narrow gaps of the high-conductivity tubes. Cooling water runs through the tubes in a strict counter-current direction at high velocity, executing a thorough indirect heat extraction.
Core Technical Advantages
l Extreme Heat Exchange Area (30%+ Efficiency Boost): The unique multi-tube matrix configuration completely shatters the surface area limitations of conventional single or dual-layer drums. This configuration multiplies the contact perimeter, boosting heat exchange efficiency by over 30% and delivering a steep cooling curve for highly conductive graphitic or carbonaceous elements.
l High-Value Counter-Current Heat Recovery: Engineered with an efficient thermodynamic counter-current flowsheet. The cooling water captures the immense sensible heat from the hot material and redirects it into the plant's water utility, converting waste heat into direct system thermal efficiency gains.
l Gentle Monolithic Rotation Protecting Material Integrity: The helical flights, tube bundles, and outer drum shell rotate together as one solid body. Because there is no harsh mechanical shearing or scraping resistance inside, it significantly prevents granular activated carbon or graphite from degradation and secondary powdering during transportation.
l Robust Water Path Engineering: The internal fluid channels are optimized for anti-scaling and velocity thresholds. The system accepts standard industrial circulating loop water or raw water, bypassing any need for complex chemical water-purification infrastructure.
l Digital VFD Linear Tuning: Equipped with a high-reliability industrial variable frequency controller as standard. Operators can execute linear adjustments of the discharge capacity by fine-tuning the drum speed, facilitating seamless integration with continuous production lines.
