Roller Belt: This is fixed to both sides of the dryer body, supporting the entire dryer and ensuring stable drum rotation.
Application Areas
1. Livestock and Poultry Manure Treatment: Livestock and poultry manure, such as chicken, cattle, and pig manure, with a moisture content of approximately 80%, can be dried to below 30%, achieving harmless treatment and resource utilization, producing organic fertilizer.
2. Sludge Composting: This is used to reduce the moisture content of sewage treatment plant sludge, facilitating subsequent fermentation and land utilization, and reducing sludge pollution.
Working principle of Rotary Drum Drying Machine:
First, a heat source such as natural gas, biomass combustion, or a steam heat exchanger heats the air, generating high-temperature hot air, typically between 150-300°C. Wet material enters the rotating drum through the feed port. Inside the drum, a lifting plate or material-lifting device continuously lifts and drops the material as the drum rotates, evenly dispersing it within the dryer. The hot air contacts the material in either co-current or counter-current flow, transferring heat to the material. The moisture in the material is vaporized and discharged with the hot air. The exhaust gas is then treated with dust removal and discharged through the discharge port. The dried material is discharged with a moisture content as low as 10%-15%.
Advantages of Rotary Drum Drying Machine:
1. High Production Capacity:
Highly mechanized and capable of continuous operation, it meets the needs of large-scale production.
2. Stable Operation:
Excellent structure ensures low resistance to material passing through the drum, resulting in smooth operation, easy operation, minimal troubleshooting, and low maintenance costs.
3. Excellent Drying Performance:
Various lifting plate designs ensure more efficient exchange between the material and the hot flue gas, resulting in high thermal energy utilization and uniform drying. The dried material has a low and uniform moisture content.
4. Environmental Protection and Energy Saving:
Some equipment is equipped with an exhaust gas treatment system to reduce dust and exhaust emissions. At the same time, through rational structural design and thermal energy utilization, energy consumption is reduced.
5. Long Service Life:
The drum and internal components are made of high-quality wear-resistant and corrosion-resistant materials. Combined with a rational structural design, the equipment has a long service life.

What types of organic fertilizer raw materials are suitable for a rotary dryer?
Rotary dryers for organic fertilizer have a wide range of applications, including livestock and poultry manure (chicken, cow, and sheep manure), composted straw, biogas residue, fermented food waste, and organic fertilizer derived from traditional Chinese medicine residues. Their core advantage is their ability to process paste, granular, or lumpy organic fertilizer materials with a moisture content of 25%-60%. By adjusting the drum speed and hot air temperature, they can tailor the physical properties of different raw materials (such as viscosity and density) to avoid clumping or wall sticking during the drying process.
What is the controlled moisture content of the dried organic fertilizer? Does it meet national standards?
The equipment can stably control the moisture content of organic fertilizer to 8%-15% based on user needs, and can further adapt to subsequent granulation, packaging, or long-term storage requirements. For high-purity organic fertilizer, the moisture content can be reduced to 8% by adjusting the hot air system parameters. The following improves product shelf life and market competitiveness.
"Does the drying process generate odor or dust? How is it handled?
The equipment is equipped with an exhaust gas purification system and dust collection device to effectively control odor and dust pollution: ① The hot air furnace uses high-temperature combustion technology to reduce volatile organic compounds (VOCs) in organic exhaust gas; ② The exhaust gas is treated in a spray tower (with deodorant) and an activated carbon adsorption tower, achieving an odor removal rate of over 90%; ③ The drum inlet and outlet are equipped with sealing devices and pulse bag dust collectors, with dust emissions ≤30mg/m³, avoiding raw material waste and air pollution.
"Do the voltage and frequency vary in different regions? Is the equipment compatible?
It supports multiple voltage and frequency adaptation to meet different user needs: 220V/60Hz (for North America), 380V/60Hz (for Southeast Asia), or 120V/60Hz (for Southeast Asia) can be customized. The 415V/50Hz electrical system (applicable to some European countries) is equipped with corresponding standard plugs and cables, eliminating the need for user modification. The manufacturer can also provide local certification (such as CE and UL) to ensure that the equipment complies with the electrical safety standards of the importing country.
