Three-Layer Rotary Drum Dryer_Drying Equipment_Products

TONY Three-Layer Rotary Drum Dryer is on the basis of a single cylinder dryer, the three different diameter of the drum assembly together, generally adopt tug drive, driven by 2-4 motors, by a frequency converter to control synchronization. The horizontal installation of the cylinder has no inclination, the installation is relatively simple, and the floor area is small. Because the middle cylinder and outer cylinder of the three-cylinder dryer are completely sealed, while greatly improving the thermal efficiency, it also causes maintenance difficulties; In the design and production, we should fully consider the material of the equipment, the robustness of the lifting board and other factors, and design a reasonable and fine three-cylinder dryer to greatly improve the life.

TONY Three-Layer Rotary Drum Dryer is suitable for granular materials, but it is not suitable for viscous materials, slender materials, and large materials.Raw materials need a certain percentage of moisture to be made into high-quality pellets. The drum dryer can help you dry the moisture content of the raw materials from 60% to about 10%.

In the drying operation of wood chips, the whole drying process is the full heat of the material and high temperature air flow. The design concept of the three-cylinder dryer is: the initial heating of the inner cylinder, that is, the preheating stage, high temperature drying; In the middle cylinder is the constant temperature heat exchange process; The outside is low temperature.

TONY Three-Layer Rotary Drum Dryer An improved energy-saving product based on the single cylinder rotary drum dryer. Improve the internal structure of the original single Drum Dryer, increase the pre-drying of wet materials before the machine and extend the drying time of wet materials in the machine, coupled with sealing, heat preservation and reasonable supporting measures, so that the production capacity of the dryer is increased by 50-80% compared with the original single drum dryer. The unit volume evaporation intensity can reach 120-180kg/m3, and the standard coal consumption is only 6-8kg/t. Its advanced technology, reasonable operating parameters, simple and feasible operation, widely used in various industries of slag, clay, coal

TONY Three-Layer Rotary Drum Dryer is to change the single cylinder body of the single cylinder dryer into three cylinders stacked together to shorten the outline size of the drying body. When the machine is working, the material and hot gas flow into the inner to outer cylinder in turn, after the Z-shaped reciprocating flow of the body, the heat energy is fully used to dry the material before unloading.

The cylinder part of TONY Three-Layer Rotary Drum Dryer is composed of three inner, middle and outer cylinders placed horizontally, which makes the cross section of the cylinder be fully utilized.

1.Feeding System

It is used to bring the material with relatively high humidity into the dryer for drying. Feeding system mainly includes hopper, conveyor and so on.

2.Three Cylinders

The three-cylinder dryer is mainly composed of three rotating cylinders installed in parallel, and there are loose holes on the wall of the cylinder for air discharge and air intake. The three cylinders are independent of each other, and each completes the drying work, and the hot air passes through it for heat transfer. The method of "common heat, common smoke, common gas, and single force" is adopted between the three cylinders to make the drying operation more scientific and reasonable.

3.Hot Air System

It is a key component of the three-cylinder dryer, which is responsible for transporting hot air to the rotating cylinder for drying. The hot air system consists of blast fan, hot air boiler, hot air pipeline, etc.

4.Discharge System.

The material enters the inner Layer of the rotary drum by the feeding device to realize the downstream dry supply under the sheet plate of the upper inner layer, and the scattered product realizes heat exchange by spiraling. The material moves to the inner product and slides into the middle layer for countercurrent dry supply. The material is repeatedly lifted into the middle layer in a two-step way. The material in the middle layer not only fully absorbs the heat emitted by the inner cylinder, but also absorbs the heat before the middle layer is rolled, and at the same time extends the drying time, the material reaches the most dry state here. Material line to middle layer another. The end falls into the outer layer, and the material travels in a rectangular multi-loop mode in the outer roller, and the material that achieves the drying effect travels rapidly under the action of hot air and is discharged from the roller, while the wet material that does not achieve the drying effect cannot travel rapidly due to its own weight, and the material is fully dried in the rectangular sheet to complete the drying purpose.

The Temperature Of The Combustion Furnace:

The temperature is too high will shorten the service life of the inner cylinder of the dryer (the oxidation and deformation of the steel plate in the inner cylinder of the dryer, long-term dry burning will lead to the scrapping of the dryer), too low will make the water content of the dry material rise, the product grade is reduced, and even unqualified. Therefore, the combustion chamber temperature is generally held at 750-850 ° C.

Additionally,the temperature bump of the combustion chamber can be adjusted by increasing or decreasing the fuel and air volume. If the combustion chamber temperature is too high, the fuel or air volume should be reduced. On the contrary, the amount of coal intake and air blast will be increased.

Please contact TONY for detailed information.

Smoke Exhaust Temperature:

Smoke exhaust temperature refers to the flue gas temperature leaving the dryer, the temperature is too high will increase energy consumption, the cost rises, the dust collector bag burnt; If it is too low, the water content of the material will rise, and the condensation will be formed simply, which is not conducive to the operation of the subsequent dust collector, so the exhaust gas temperature is generally held at about 90 ° C.

The bump of the flue gas temperature can be adjusted by increasing or decreasing the amount of wet material entering the dryer. If the flue gas temperature is high, the amount of wet material entering the dryer can be increased. On the contrary, the amount of wet material entering the dryer should be reduced
