The three-cylinder dryer is composed of three concentric but different diameter cylinders nested together, and they are interlocking. This special structure determines its capacity, so it is also called a three-pass dryer. The three-cylinder dryer can be optimally configured according to the size of the site, and use coal, oil, gas, biomass fuel and other energy forms to dry materials as needed. The three-cylinder dryer has a compact structure and a small area requirement, about one-half of the area occupied by a single cylinder with the same capacity. It has stable work, low energy consumption, high thermal efficiency, good material drying effect, and easy automation control and fewer operators.

This equipment is used to dry raw materials such as yellow sand, river sand, quartz sand, slag, clay, etc., and is widely used in building materials, chemical, casting and other industries.

In addition, fuel burners, combustion chambers or supporting elevators, belt conveyors, metering feeders, cyclones, pulse dust collectors and spray towers can be designed according to user needs.

1. The cylinder is designed to be self-insulating, so that the thermal efficiency can reach over 70%.

2. The product structure is exquisite and the operation is stable.

3. The drying effect is good, and the coal consumption per ton of dry material is less than 8KG.

4. The fuel can be coal, oil and gas.

5. Compared with the single-cylinder dryer, it occupies about 50% less land, and the power consumption is reduced by 60%.

6. The required final moisture index can be easily adjusted according to user requirements.

7. The air outlet temperature is low, and the dust removal equipment can be used for a long time.

8. Supporting wheels are used for rotation to replace the large and small gears. Stable operation.

9. The discharge temperature is lower than 60 degrees.

The material enters the inner cylinder from the feeding device to achieve downstream drying. The material is continuously picked up and scattered under the lifting plate of the inner cylinder to achieve heat exchange in a spiral manner, and the material moves to the other end of the inner cylinder and drops the middle cylinder for counter-current drying. The material is continuously raised in the middle cylinder, showing a two-step forward and one-step backward moving mode. The material in the middle cylinder not only fully absorbs the heat emitted by the inner tube body, but also absorbs the middle cylinder. It also prolongs the drying time, and the material reaches a dry state here. The material travels to the other end of the middle cylinder and falls into the outer cylinder. The material travels in the outer tube in a rectangular multi-loop manner to achieve the drying effect and quickly discharges out of the dryer under the action of hot airflow. The wet material that does not achieve the drying effect cannot be fast due to its own weight. As it progresses, the materials are fully dried in the rectangular lifting plate, thereby achieving the drying effect and completing the drying process.
