1、 Working principle

The rotary kiln drum dryer is mainly composed of a drum, a combustion chamber, a feeding device, a discharging device, and a transmission device. Its working principle is to directly heat the materials inside the drum through the high-temperature flue gas generated by the combustion chamber, causing the moisture in the materials to evaporate, thereby achieving the purpose of drying. The drum rotates slowly under the drive of the transmission device, which evenly heats the material inside the drum and improves the drying efficiency.

2、 Structural characteristics

Drum structure: The drum is usually made of high-quality steel plate, with a lifting plate on the inner wall, which can effectively improve the flipping and dispersion of materials, increase the contact area between materials and hot air, and improve heat transfer efficiency.

Combustion chamber: The combustion chamber is an important component of the rotary kiln drum dryer, usually using fuels such as natural gas, coal powder, or heavy oil. The high-temperature flue gas generated by the combustion chamber directly heats the material through the inside of the drum.

Feeding device and discharging device: The feeding device and discharging device are located at both ends of the drum, which can achieve continuous feeding and discharging of materials, ensuring the continuity and stability of the drying process.

Transmission device: The transmission device usually uses an electric motor and a reducer to drive the drum to slowly rotate through gears or chains. The design of the transmission device should ensure the smooth operation of the drum, reduce vibration and noise.

Sealing device: The inlet and outlet are equipped with sealing devices, which can effectively prevent the leakage of hot air and dust, ensuring the normal operation of the equipment and the cleanliness of the operating environment.

3、 Application Fields

Rotary kiln drum dryer is widely used in industries such as chemical, petrochemical, dye, food, pharmaceutical, metallurgy, etc. Specific applications include:

Sludge Drying: Suitable for sludge drying in sewage treatment plants, it can efficiently remove water from sludge, reduce sludge volume, and facilitate subsequent treatment and resource utilization.
