The asphalt plant dryer drum is a device for drying and heating cold and wet aggregates. The function of asphalt plant dryer drum varies with different types of asphalt plants. For the asphalt drum plant, the function of the asphalt plant dryer drum is to dry and heat the cold aggregate and mix the mixture; For the asphalt batch plant, the asphalt plant dryer drum is only a place for drying and heating the cold aggregate, and does not have the function of mixing the mixture. Generally speaking, the role of asphalt plant dryer drum is to preheat the cold aggregate, dehydrate and dry it, and heat it up to ensure that the discharge temperature meets the specified requirements.
Luton asphalt plant dryer drum is featured by high efficient, low consumption and less pollution, and it also performs well in RAP mixing plant. It’s worth buying. This post takes the asphalt plant dryer drum of the continuous asphalt plant as an example for relevant explanation.
Specification of Asphalt Dryer Drum
Why Choose LUTON Asphalt Plant Dryer Drum
When the dryer drum rotates clockwise, the aggregate in the drum is heated and dried; When the drum rotates counterclockwise, the hot asphalt mixture in the drum is discharged. In addition, the drum, drum shaft and drum body are made of durable and wear-resistant stainless steel to ensure effective and stable heating.
The asphalt dryer drum can be installed on the mobile frame to facilitate the transportation, and it can be installed at any time when it is ready for use.
The asphalt dryer drum is an independent unit, which makes the installation and disassembly very easy. Besides, it’s convenient to clean and maintain.
The type of burners can be selected by the customer. There are three types of burners: coal, oil and gas. The prices of the three combustion types are different, and they are selected according to the convenience of local fuel procurement. Customers can customize specific types according to the actual situation.
Great Insulation Effect
Our drum is coated with 50mm thermal insulation layer. On the one hand, this layer helps to maintain heat, on the other hand, it helps to shorten the cooling time of the drum after production.
The inner drum is designed with numerous geometric blades gotten in touch with bolts, utilized for lifting aggregates throughout drum turning.
Furthermore, our burner, from time-honored Italian brand name that is specialist in making high efficiency combustor, possesses high ignition success rate and automated temperature level regulating system.
Hence, virtually 0 heat loss and 30% greater functioning efficiency can be ensured, compared to} the typical layout.
The drum is driven by 4 friction wheels, and freely link, ensuring smooth, stable and even work.
The drying system is equipped with the intelligent temperature control system of Honeywell, a famous American temperature sensor expert in industry.
How to Choose the Suitable Asphalt Dryer Drum
Take a look at the Thermal Performance
Decreasing the dampness content of cold aggregates is the most efficient means to increase thermal performance and also lower energy consumption.
Nevertheless, there is no way to control the moisture content of the virgin material before drum drying to a huge extent.To much better remove moisture in the cold aggregates, you should pay much interest to the drum framework.
Firstly, there need to be a thermal insulation layer covered on the drum body. After that, the stainless-steel made framework executes well in insulating heat.
Consider the Structure
The practical structure below describes angled drum, forms of blades and also the drive wheels.
The drum installed aslant is more convenient to release the dried out material.
You must also look at the material blade inside of the drum. In current market, the blades are made with L form, T shape, Z shape, geometric shape and more.
To better raise the aggregates inside the rotary drum, undoubtedly, geometric-shaped blade does the best.
Regarding to the drive ring, for security, the drive wheels and also roller shafts made from stainless-steel or steel alloy are the best choice. Then, the support roller driven by the rubbing of the polymer (from the motor and gear assembly) does well for high stability and low noise.
Look at the Combustion Engine
Combustion engine is the critical core of the burning system. A good burner could save you much cost on fuel consumption.
To ensure low exhaust emission, an engine from world famous brand never disappoint you.
Usually, Italian oil burner is a positive choice.
Look st the Sealing System
Ensure the dryer drum you buy has a good sealing. A professional seal can largely reduce the heat loss, ensuring a more stable nature of the aggregates.
