Промышленная цилиндрическая сушилка для летающей золы вращающаяся трехбарабанная

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. 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.

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.
