By optimizing the process system parameters and selecting reasonable operating parameters, the single-drum dryer has greatly improved thermal efficiency and reduced energy consumption. Its coal consumption and electricity consumption are 30-70% lower than those of general dryers, and the hourly output is increased by 50-85%.
Single-drum dryer, also known as rotary drum dryer and single-drum horizontal dryer, is an efficient and widely used drying equipment.
Single-drum dryer has a long strip drying drum, with a rotating shaft and gear system inside, and a heater and cooling device outside. This structure allows the material to be evenly heated in the drum, thereby achieving an efficient drying effect.

The single-drum dryer is widely used in food, chemical, pharmaceutical, agriculture, building materials, metallurgy, mineral processing, and other fields.
The drying drum of the single-drum dryer has a large diameter, which can accommodate more materials, and the drying requirements of different materials can be met by adjusting the length of the drying drum. It adopts a fully automatic control system, which is simple and convenient to operate. The structure is simple and easy to clean and maintain.
The movement of the material is due to the combined effect of inclination of the shell to the horizontal and the internal tumbling action or mechanical turn over thus the name tumbling dryer.
The cylinder body of the dryer is made of steel material, which has the characteristics of high hardness and high toughness; and compared with other materials, its wear resistance is higher.
Due to the high air velocity, the material is well dispersed in the gas phase, and the entire surface of the material can be used as the effective drying area, so the limited drying area is greatly increased.
The dryer system has good sealing performance and is equipped with a complete dust removal device so that the dust is small and the operating environment is good.
The new internal structure strengthens the cleaning and heat conduction of the dispersed materials.
1. Heat conduction: The single-drum dryer is usually equipped with a heat source system, such as a hot air furnace or a burner, to generate high-temperature hot air flow. The hot air flow enters the drum through the hot air duct of the dryer and comes into direct contact with the wet material. The moisture in the wet material evaporates rapidly at high temperature and is carried away by the hot air flow, thereby achieving the drying of the material.
2. Material tumbling: The drum of the single-drum dryer rotates under the drive of the motor. There is a lifting plate or other stirring device inside the drum. When the drum rotates, these devices will continuously turn up and scatter the material, so that the material is continuously tumbled and mixed in the drum. This tumbling and mixing helps the material to fully contact with the hot air flow and improve the drying efficiency. At the same time, tumbling can also prevent the material from forming accumulation and agglomeration in the drum, ensuring that the material is evenly heated.
3. Material conveying: During the rotation of the drum, the material will be affected by a certain gravity and the inclination angle of the drum, and thus move along the drum to the discharge end. This continuous material conveying process ensures the residence time of the material in the drum, so that the material is fully dried.
