Rotary kiln drum dryer is a common drying equipment, mainly used for drying powder or granular materials in industries such as building materials, chemicals, metallurgy, food, and pharmaceuticals. Its working principle is mainly to use a rotating drum to diffuse the moisture in the wet material into the hot air through heat exchange, gradually drying the material.

The specific working principle is as follows:

1. Material conveying: The material is fed into the rotary kiln from one end and moves axially inside the kiln.

2. * * Heat exchange * *: Inside the drum, hot air exchanges heat with the material. Hot air is usually heated by a burner, and the temperature and humidity can be adjusted according to the drying requirements of the material.

3. Moisture diffusion: The moisture in the material diffuses with the flow of hot air, and the heat causes the moisture to evaporate. In this way, the material gradually becomes dry.

4. * * Waste gas emissions * *: The waste gas generated during the drying process, along with the evaporated water, is discharged from the other end of the rotary kiln. This part of the exhaust gas can be treated through purification equipment to reduce its impact on the environment.

5. Drying degree control: By adjusting the temperature, humidity, and drum speed of the hot air, the drying degree of the material can be controlled.

6. * * Discharge * *: The dried material is discharged from the other end of the drum for further processing or packaging.

Rotary kiln drum dryer is widely used due to its advantages of good drying effect, high efficiency, and easy operation. At the same time, the device also has strong adaptability and can be adjusted according to different materials and drying requirements.

The rotary kiln drum dryer is mainly used for pre firing hard ferrite powder, and can also be applied in industries such as cement, metallurgy, and chemical engineering. The equipment consists of a main kiln and its supporting transmission device, cooling pipes, fuel system, electrical control, secondary air inlet device, exhaust and dust removal device, and preheating kiln body. It has functions such as over temperature alarm, overload alarm, automatic control of working temperature, and adjustable oxygen in the kiln.

Rotary kiln drum dryer is a widely used drying equipment, with the following main characteristics:

1. Good drying effect: Due to the full contact between the material and hot air inside the drum, the drying effect is good and uniform.

2. Wide applicability: Rotary kiln drum dryer can be used to dry various types of materials, such as powder, particle, fiber, etc.

3. High drying rate: The rotation of the drum increases the contact area between the material and the hot air, thereby improving the drying rate.

4. * * Easy to operate * *: This device has a simple structure, is easy to operate, and is easy to maintain.

5. Energy saving and environmental protection: The rotary kiln drum dryer has relatively high thermal efficiency and low energy consumption. Meanwhile, exhaust gas can be purified to reduce its impact on the environment.

6. High strength and long service life: The equipment is made of high-quality materials, which have high strength and durability, and a long service life.

7. Good safety: The equipment has multiple safety protection measures, such as overload protection, temperature control, etc., to ensure the safety of the production process.

8. * * Continuous operation * *: The rotary kiln drum dryer can achieve continuous operation, improving production efficiency.

9. Flexible adjustment: Drying parameters (such as temperature, humidity, speed, etc.) can be adjusted according to actual needs to meet the drying requirements of different materials.

10. * * Compact structure * *: The device occupies a small space, making it easy to install and transport.

In summary, the rotary kiln drum dryer has the advantages of good drying effect, wide applicability, high drying rate, easy operation, energy saving and environmental protection, high strength, long service life, good safety, continuous operation and flexible adjustment. It is a very practical drying equipment.

1. Drying of the following materials is carried out in industries such as pharmaceuticals, food, and chemicals.

2. Suitable for paste like, paste like, and powdery materials.

3. Thermally sensitive materials that require low-temperature drying.

4. Easy to oxidize and strongly stimulate.

5. Require the recycling of materials containing organic solvents.
