The three-cylinder dryer is an improved energy-saving product based on the single-cylinder rotary dryer. It has been recognized by many industries and has achieved good results. This equipment increases the pre-drying design of the wet material before entering the machine and prolongs the drying time of the wet material in the machine, and installs sealing, heat preservation and reasonable supporting measure. So the efficiency of the dryer's production capacity is greatly improved. The advanced technology, reasonable operating parameters and easy operation, make it widely used in the drying process of sand, slag and other mixed materials from various industries. The material exchanges heat between the inner cylinder and the hot air flow in the form of radiation, convection, and conduction, and the heat exchange in the outer cylinder is combined with conduction and convection. Therefore, the thermal efficiency is high and the energy saving effect is significant. Moreover, the importance is the outlet temperature of this dryer is low, which helps to extend the service life of the tail dust removal system.

Scope of application: iron powder, mineral powder and other mixed materials, dry-mixed mortar, yellow sand in the construction industry, and raw materials in the chemical, foundry 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.

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.

Gongyi Derui Machinery Co., LTD entered the mechanical industry from the beginning of the 1980’s, earlier than most factories. With the company philosophy these years, our products are sold to many customers from home and abroad, popular in India, Russia, Kazakhstan, Africa, South America, Mid-East, Southeast Asia, and almost 30 countries and areas. And it is our honor to make a contribution of to the development of these countries.
