What is the rotary dryer machine ?
This is a large-scale industrial machine featuring powerful drying capabilities and energy-saving performance. It can meet a variety of drying standards. The video below showcases the machine’s unique design and production features.
Efficient Pelletizing Capability
The machine employs a dual-layer drum design, using drum rotation and hot air circulation to dry the material. As a large-scale industrial machine, it occupies a significant amount of floor space and is ideal for large-scale drying operations. For applications with limited space, we have also designed a three-layer drum dryer.
For ease of adjustment of the drying level, there is a variable frequency drive and a thermometer on the equipment. Due to the high-temperature drying environment inside, a spark detection and fire suppression system has been specifically installed. This helps prevent fires and ensures production safety.
The rotary drum dryer is ideal for drying fibrous, lumpy and agglomerated powdered biomass materials. It is fitted with lifting plates inside to effectively lift the material and enhance the drying effect. For materials requiring pelletization, it can easily reduce their moisture content to the ideal range of 15–18%.
Suitable Materials
This rotary dryer machine offers high operational efficiency. It can dry a wide variety of materials, including wood chips, sawdust, grass meal, and rice husks. A single unit can be used for multiple production scenarios. Furthermore, processing materials through this machine can significantly enhance pelletizing results. It addresses the issue of soft, collapsed pellet structure and improves the forming rate.

Innovative Structural Design
Our rotary dryer machine features a scientifically designed structure and is constructed from high-strength materials. Therefore, its service life is significantly extended. Through innovative drying methods, it achieves high efficiency and energy savings.
Support Roller
The device serves to secure and support the drum. Both the roller rings and guide wheels are made of cast steel, offering high hardness and wear resistance to provide excellent support.
Drum
Typically, the drum features a double-layer design. To save space and improve drying efficiency, we have also designed a triple-layer drum. The thickness of a single layer is 15 mm.
Material-Lifting Blades
These blades, 6 mm thick, are arranged in a spiral pattern along the inner and outer walls of the drum. As the drum rotates, they continuously lift the material to achieve better drying.
Fan
This unit is installed at the rear of the drum dryer machine to provide airflow and extract the dried material. This method facilitates material discharge. The fan in a three-drum dryer is larger.

What types of raw materials can a rotary dryer machine dry?
This dryer is a large-scale industrial machine suitable for drying raw materials used in industrial production. Examples include various lumpy, powdery, or clumpy materials. The most common applications involve biomass raw materials used for pelletizing, such as ground wood chips, straw powder, grass powder, and rice husks.
Additionally, its highly efficient drying performance makes it suitable for drying river sand, mineral sand, and organic fertilizer. Since moisture content and drying standards vary by material, drying times must be adjusted accordingly. Our dryer is capable of accommodating these variations, ensuring consistent production performance.
–
What moisture content can a rotary dryer achieve?
This primarily depends on the production objective. For raw materials intended for pelletization, the ideal moisture content is 15–18%. Our dryers can handle materials with a wide range of moisture levels and dry them to the ideal moisture content for pelletization. Additionally, the equipment is equipped with a variable frequency drive, allowing for adjustment of drying times to accommodate various drying requirements.
–
Does our rotary dryer machine consume a lot of energy during production?
This equipment achieves drying through an external supply of hot air and its own rotation. Furthermore, its multi-layer drum design provides excellent heat retention, thereby making better use of the heat source. As a result, this dryer can reduce production energy consumption by more than 20%.
Production energy consumption also depends on the choice of hot air furnace and burner. We offer hot air furnaces and biomass burners. These units use biomass feedstock as fuel, significantly reducing production energy consumption. Additionally, you can choose to build your own hot air furnace, which will also deliver excellent production results.
–
Is this rotary dryer equipped with an automated control system?
Our rotary dryers are equipped with a PLC control system, enabling highly automated production. This system allows you to adjust drying temperature and duration, control feed rate, monitor for abnormalities, and automatically extinguish fires. As a result, it not only ensures efficient production but also reduces labor costs and guarantees production safety.
