The three-cylinder dryer is a high-efficiency and energy-saving product improved on the basis of the single-cylinder tumble dryer in our factory according to market needs. After the application of many enterprises and many industries, good drying effect has been achieved. The three-cylinder dryer improves the internal structure of the single-cylinder tumble dryer, increases the pre-drying design of the wet material before entering the machine and extends the drying time of the wet material in the machine, and installs sealing, heat preservation and reasonable supporting measures. So compared with the original single-cylinder tumble dryer, the production capacity of the three-cylinder dryer is increased by 50-80%, and the evaporation strength per unit volume can reach 120-180kg/m3, and the standard coal consumption is only 6-8kg/t.

With advanced technology, reasonable operating parameters, simple and feasible operation, it can be used in slag, clay, coal, iron powder, slag powder and other mixed materials, also widely used in dry-mixed mortar, yellow sand, etc. of the construction industry, as well as chemical, casting, etc. industry.

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. With high technical design of self-insulation of the cylinder, the thermal efficiency is as high as 70% (the thermal efficiency of the single-cylinder dryer is only 35%), which saves 68% of coal than the single-cylinder dryer.

2. The length of the three-cylinder dryer is 60% shorter than that of the single-cylinder dryer, reducing the building area of the plant.

3. It adopts heat-resistant abrasion-resistant alloy steel plate, which is 4 times more wear-resistant than ordinary steel plate. Long service life and easy maintenance.

4. High thermal efficiency, the temperature of the outer cylinder is lower than 60℃ (the temperature of the outer cylinder of the single cylinder dryer is as high as 150℃), and the outlet temperature is lower than 60℃.

5. The outlet temperature is low, which is conducive to the long use time of the dust removal equipment. It can be directly matched with the pulse bag filter.

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

7. The fuel can be adapted to coal, oil and gas.

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.

1. Before sales, we sales team will know know the real situaiton from our customers, such as the feeding size, crushing capacity, final sizes and the electricity condition,etc. then our technician team will design proposals according the situations, and we will update the solution according to customer's further requirements.

2. After concluding the contract, our engineer technician will prepare the foundation drawing about the equipemnts. at the same time, our production factory will prepare the equipment timely.

3. After delivery, our installation engineer will be ready to guide the installation and commissioning for the equipment, to make sure that each item going smoothly and meet the customer's requirements.
