Product Description
Product Overview
The TONGZHENG Single-Drum Dryer is a rotary drying machine widely used for removing moisture from granular and powdery bulk materials in mining, building-material, chemical and other industries. The optimized drum structure and hot-air circulation provide effective moisture removal and improved drying efficiency. Inside the rotating drum, continuous lifting and tumbling of the material promote thorough contact with the hot air, helping achieve consistent final moisture content. Efficient heat transfer and optimized airflow help reduce heat loss and fuel consumption during continuous operation. The robust construction is designed for long-term industrial operation, with convenient access for inspection and maintenance, making it a reliable and durable solution for high-capacity drying processes.

What Is a Single-Drum Dryer?
A single-drum dryer is a rotary drying machine consisting of a large inclined rotating cylinder, a heating unit and a feeding and discharging system. Wet material is fed into the upper end of the rotating drum and is continuously lifted and tumbled by internal flights, exposing it to the hot air stream so that moisture is evaporated and carried away with the exhaust gas. In parallel-flow operation, the material moves in the same direction as the hot air, allowing gentle and efficient drying of heat-sensitive materials. The dried material is discharged from the lower end of the drum, and the final moisture content can be controlled by adjusting the drum speed, feed rate and inlet air temperature, making the single-drum dryer a reliable and economical solution for large-scale drying of granular bulk materials.
Applications
- Drying of sand, slag, coal, clay and other granular bulk materials in building-material plants
- Moisture removal for mineral powders and ores in mining and beneficiation processes
- Drying of fertilizers, chemicals and other granular products in chemical and fertilizer industries
- Pre-drying and moisture control in cement, gypsum and industrial solid-waste processing lines
