Three-drum dryers have been widely used in many industries due to their advantages of high efficiency, energy saving, environmental protection, and easy operation. With the continuous development and innovation of technology, it is believed that three-drum dryers will play a more important role in the future.
The three-drum dryer is an efficient and energy-saving industrial drying equipment, which is improved and innovated on the basis of the single-drum rotary dryer.
The three-drum dryer is a large-scale industrial equipment that completes the material drying process through hot air or gas heating. Its structural feature is that it consists of three rotating cylinders stacked together, each cylinder has an independent drive device and hot air or gas heating equipment.
The three-drum dryer adopts advanced drying technology, which can greatly improve drying efficiency and reduce energy consumption. Compared with traditional drying equipment, its energy-saving effect can reach more than 30%.
The three-drum dryer is suitable for drying various materials, such as slag, clay, coal, iron powder, etc. At the same time, it can also be adjusted and optimized according to the characteristics and drying requirements of the materials to meet the needs of different industries.
The three-drum dryer adopts an advanced control system, which can realize automatic operation.
The waste gas generated by the three-drum dryer during the drying process can be discharged after treatment, which meets the national environmental protection requirements.
The working principle of the three-drum dryer is mainly based on the two drying methods of co-current and counter-current, and the material is fully dried through the heat exchange of multiple drums. The specific process is as follows:
| Model | Diameter of outer cylinder(m) | Length of outer cylinder (m) | Drum volume(m³) | Rotation speed(r/min) | Max. air flow temperature(℃) | Production capacity(t/h) | Power(kw) |
| Ф2.0*4m | 2 | 4 | 12.56 | 4-10 | 700-750 | 8-15 | 5.5x2 |
| Ф2.2*5m | 2.2 | 5 | 18.99 | 4-10 | 700-750 | 12-20 | 5.5x2 |

| Ф3.0*7m | 3 | 7 | 49.45 | 4-10 | 700-750 | 30-45 | 7.5x4 |
| Ф3.2*7m | 3.2 | 7 | 56.27 | 4-10 | 700-750 | 35-55 | 11x4 |
| Ф3.6*8m | 3.6 | 8 | 81.39 | 4-10 | 700-750 | 55-75 | 18.5x4 |
| Ф4.0*10m | 4 | 10 | 125.60 | 4-10 | 700-750 | 70-100 | 22x4 |
