What is a Rotary Drum Dryer?
FANQUN rotary drum dryer is an industrial drying equipment.
Wet materials enter from the high end and are repeatedly lifted and scattered as the drum rotates. Meanwhile, hot air passes through the drum, conducting thorough heat exchange with your materials, causing the moisture to evaporate rapidly. During this process, the material moves towards the lower end under the action of gravity and completes the drying process, and is finally discharged from the discharge end.
It is widely used in various industrial drying processes due to its large processing capacity, stable operation and wide adaptability.
The Working Principle of the Rotary Drum Dryer
- Step 1: Wet materials are continuously fed into the high end of the drum through the feeding device. As the drum rotates slowly, the materials at the bottom will be lifted and carried to a certain height.
- Step 2: Under the effect of its own gravity, the material is thrown off, forming a dispersed and uniform material curtain across the entire cross-section of the drum, which greatly increases the surface area of the material.
- Step 3: The hot air driven by the fan passes through the drum and thoroughly mixes and comes into contact with the falling material curtain. Heat is rapidly transferred from the hot air to the wet material, causing the surface moisture to evaporate and vaporize quickly.
- Step 4: The exhaust gas, which has completed heat exchange and carries a large amount of water vapor, is discharged from the drum exhaust system and then enters the subsequent dust removal system. After the fine dust carried is recovered, the clean gas is discharged into the atmosphere.
- Step 5: The dried material will be discharged from the bottom of the rotating drum desiccant, and you can then proceed to the next processing step.
The Features and Advantages of Rotary Drum Dryers
Cylinder Structure
The FANQUN rotary drum dryer is equipped with a long cylindrical drum. This structure ensures that the heat of your materials is evenly distributed during the drying process. In addition, our rotary drum dryers are available in both single-drum and double-drum configurations. You can choose the appropriate configuration according to your application and the scale of the material.
Continuous Feeding and Discharging
Our equipment adopts a mechanical feeding device to continuously feed wet materials from the high end, while the dried products are continuously and automatically discharged from the low end. It can efficiently handle your large quantities of materials and is perfectly adapted to industrial large-scale continuous production processes.
Sturdy Structure
The rotary drum dryer adopts high-strength materials and a reinforced drum structure. This solid mechanical construction endows the equipment with outstanding load-bearing capacity and fatigue resistance, enabling it to withstand heavy loads and achieve continuous and stable operation without interruption.
High-Efficiency Heat Transfer
The materials inside the drum are repeatedly lifted and scattered, causing a sharp increase in the surface area of the materials. This enables the high-temperature gas flow to have full and direct contact with the surface of the materials, which accelerates the efficiency of heat transfer and water vapor evaporation.
High-Efficiency Dust Removal
The exhaust gas produced after drying will enter the matching high-efficiency dust removal system, which can capture and separate the vast majority of dust carried in the exhaust gas, ensuring that the final emission meets environmental protection requirements and effectively recovering valuable products.
Operational Stability
Due to its robust mechanical structure and continuous working principle, the FANQUN rotary drum dryer can operate stably for a long time and handle a large amount of materials, making it particularly suitable for industrial scenarios that require large-scale drying.
Strong Adaptability
By adjusting parameters such as the drum speed, inclination, and hot air temperature, our rotary drum dryer can handle various materials, including granules, blocks, and filter cakes, with a large operational flexibility and a wide range of applications.
Uniformity of Drying
The materials are constantly scattered and mixed inside the cylinder, avoiding local overheating or uneven drying, thus ensuring that your final product has a good and consistent drying effect.

Sure. The rotational speed can be steplessly adjusted by the frequency converter. During installation, the inclination can be adjusted within a certain range through the gasket to control the residence time of the material in the cylinder and precisely control the drying degree of the material.
Our core load-bearing components are made of high-strength materials and undergo special heat treatment processes, featuring extremely high hardness and wear resistance on the surface. Meanwhile, we offer replaceable wear-resistant liners, which greatly extend the service life of the main body of the equipment.
By optimizing the insulation of the cylinder and adopting a waste heat recovery system for exhaust gas, we can effectively reduce the flue gas temperature, enhance the thermal efficiency of the system, which significantly lower your operating costs.
