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 three cylinders is designed to be self-insulating, to reduce heat loss;

2. Optimized design of the guide and lifting plate structure to ensure the dispersion of materials;

3. The special thermal design concept eliminates the heat loss of the wind tunnel, and the heat energy utilization rate is significantly improved;

4. Increase the heat exchange area and fully improve the evaporation intensity per unit volume;

5. The thermal efficiency is increased by more than 35%, and energy saving is more than doubled;

6. The equipment area is reduced, and the equipment basic investment is reduced;

7. High efficiency, energy saving, environmental protection, in line with the needs of environmental protection development.

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.

Firstly ------ Your raw material information

I will provide you the most suitable product and proposal according to your raw material information. Such as I need to know your raw material; your production capacity; your final product's requirements.

Secondly ------ Guidance

If customers plan to visit my factory, I will pick customers up at the airport, and then accompany with customers to test shredders in my factory. We can comminucate the most suitable machines' Commercial Invoice in my factory, and do the cooperation.

Thirdly ------ After-sale service 1

My factory will prepare product after receiving the down payment. Normally, after 5-25days preparing time, my factory will finish the machines' preparing, and then test machines for you, and I will send the testing effect to customers. Then after customers are satisfied with the testing effect, then customers will plan to send the down payment to my factory, then we load machines for customers.

Finally ------ After-sale service 2

After customers receiving the machines, my factory will dispatch technicians to install machines for customers, and teach customers how to operate machines.

Gongyi Derui Machinery Co., LTD entered the mechanical industry from the beginning of the 1980’s, earlier than most factories.
