How does a large wheel compost turner adapt to large-scale organic fertilizer production lines?

fertilizer granulator Oct 18, 2025

With the large-scale development of the organic fertilizer industry, production lines are placing increasingly stringent demands on equipment adaptability. With its exceptional integration capabilities, large wheel compost turners have become core equipment for large-scale organic fertilizer production lines.

Within the production line process, they seamlessly connect pre-treatment and processing. During pre-treatment, raw materials such as livestock and poultry manure processed by a solid-liquid separator and pulverized straw from a pulverizer are piled into windrows 5-8 meters wide and 1.5-2 meters high. The large wheel compost turner slowly moves along the windrows, turning and fermenting the material. The fermented material is then conveyed by conveyor to equipment such as granulators, screens, and dryers, forming a complete production chain from pre-treatment to fermentation, enabling continuous production.

For large-scale production lines with an annual output of over 100,000 tons, the equipment rotates through multiple windrows: one receiving fresh raw material, one performing high-temperature fermentation, and one completing cool-down composting. This fixed cycle allows for a daily processing capacity of 800-1,500 tons, meeting the needs of large-scale production.

In addition, its electronic control system flexibly adjusts the turning and travel speeds, adjusting the fermentation progress based on the raw material supply and pelletizing capacity, ensuring a stable production line. Furthermore, compared to tank fermentation, it improves site utilization by over 30%, saving valuable land resources for large-scale production lines.

Drum fertilizer dryers: Why can they adapt to the different drying requirements of organic and compound fertilizers?

fertilizer granulator Oct 17, 2025

In the fertilizer industry, the drying requirements of organic and compound fertilizers differ significantly. Organic fertilizers require rapid dehydration and fiber clumping prevention, while compound fertilizers require gentle drying to prevent particle breakage.

For drying organic fertilizers, drum fertilizer dryers offer two key design advantages: First, they utilize a “high-speed + multiple lifter” combination. High speed combined with dense lifters effectively lifts fibrous materials, preventing entanglement and clumping. Hot air also directly penetrates the material layer, quickly removing moisture. Second, an anti-stick coating on the inner wall of the drum reduces wet organic fertilizer from sticking to the wall, reducing cleaning frequency and ensuring continuous production.

For drying compound fertilizers, the drum fertilizer dryer emphasizes “gentle temperature control + low speed”: steam heating is used, keeping the temperature between 120-150°C to avoid direct contact with high temperatures that could cause cracking on the particle surface. Furthermore, a reduced drum speed reduces particle friction within the drum, keeping the particle breakage rate below 3%.

Even when processing temperature-sensitive biofertilizers, the drum fertilizer dryer can adapt to these needs through a “low-temperature hot air modification.” This reduces the hot air temperature to 60-80°C, prolonging the material’s residence time. This allows for slow dehydration while maintaining a microbial survival rate above 85%, truly achieving “one device, multiple fertilizers.”

Rotary drum granulator selection guide: Focus on core structure and match production line requirements

fertilizer granulator Oct 17, 2025

When selecting a rotary drum granulator, companies should pay close attention to its core structure to ensure it precisely matches their production line requirements. A rotary drum granulator primarily consists of a rotating drum, transmission, support system, and spray system. The performance of each component directly impacts the overall performance of the equipment.

The rotating drum, as the core working component, is constructed from rolled steel plate. Lifting plates or spiral blades on the inner wall enhance the tumbling and collision effect of the material. When selecting a granulator, consider whether the steel plate thickness and blade design are compatible with the characteristics of the production material. The transmission provides power, and the power and quality of the motor and reducer affect the equipment’s operational stability and should be selected based on production capacity.

The support system bears the weight and rotation of the drum. The selection of rolling or sliding bearings should be considered based on the equipment load and operating environment. Furthermore, the atomization effect of the spray system determines the accuracy of humidity control, ensuring uniform spraying of water or adhesive. Only by comprehensively considering these structural details can you select a rotary drum granulator that is compatible with your production line and operates efficiently.
