Formally known as the Three-cylinder Rotary Dryer, this machine is an optimized and upgraded alternative to traditional single-cylinder dryers. Its core positioning targets medium-to-large-scale drying production lines for bulk granular and powdery materials. Its objective is to efficiently reduce material moisture to the required level while lowering unit energy consumption and enhancing operational stability.Simply put, it currently stands as the primary workhorse for drying high-moisture materials such as slag, coal, and clay.
• Equipment Type: Continuous rotary drying equipment (positioned between single-cylinder dryers and multi-stage combined drying systems).
• Final Moisture: 3–15% adjustable, suitable for materials with initial moisture content up to 25%.
• Core Value: While ensuring high throughput, the machine significantly reduces heat loss and energy consumption through its three-stage cascading structure.
• Applicable Materials: Slag, coal, clay, river sand, iron ore, limestone powder, fly ash, etc.
• Industry Applications: Building materials industry slag drying, mining ore processing, chemical raw material drying, power plant coal preparation, and construction sand production lines.
Patented technology, with an Inner automatic thin-oil lubricating system, and a long oil change cycle.
Employs a three-stage cascading lifting plate design that eliminates traditional blind zones. It ensures full material-air contact, maximizes heat transfer efficiency, and significantly shortens the overall drying cycle.
Features multi-channel labyrinth sealing at both cylinder ends, effectively reducing hot air leakage. Combined with optimized airflow layout, it cuts energy use by about 20-25% vs. conventional single-cylinder dryers.
Built with thickened wear-resistant steel plates and a reinforced riding wheel system. This robust structure minimizes vibration under high loads, extends component life, and lowers long-term maintenance costs.
• Machine Positioning: Classified as a continuous rotary drying equipment, it sits between single-cylinder dryers and multi-stage combined drying systems. Primarily used for drying materials with moisture content below 25% and temperature resistance above 100℃, it handles materials such as coal, slag, clay, and mineral powders. It serves as a core, widely-applied equipment in industries including mining, building materials, and chemical processing.
• Working Principle: Wet material is fed into the inclined rotating cylinder, where it is lifted and scattered by internal lifting plates as the cylinder rotates. Hot airflow flows through the cylinder in co-current or counter-current directions, transferring heat to the material to evaporate moisture. As the material moves through the three cascading stages of the cylinder, moisture is continuously reduced, and the dried product is discharged at the outlet.
