In the production of organic fertilizers, compound fertilizers, and other granules, disc granulation technology, with its unique technical characteristics, has become the preferred solution for small and medium-sized production enterprises. Compared with traditional granulation processes, it exhibits significant advantages in pelleting efficiency, pellet quality, and operation and maintenance, helping enterprises reduce costs, increase efficiency, and enhance product competitiveness.
The core advantages of disc granulation technology lie in its high pelleting rate and high raw material utilization rate. Its inclined disc structure, combined with centrifugal force and friction, allows the raw material to fully tumble and adhere layer by layer within the disc, resulting in a stable pelleting rate of over 90%, with high-quality processes reaching over 96%, far exceeding the lower than 70% level of traditional granulation equipment. Simultaneously, a dedicated scraping device can clean the raw material adhering to the inner wall of the disc in real time, preventing material accumulation and clumping. Combined with a seamless arc design, this further improves pellet uniformity, reduces waste of unformed powder, and achieves a raw material utilization rate of over 98%, significantly reducing production costs.
Excellent pellet quality and strong stability are another major highlight. By flexibly adjusting the disc tilt angle, rotation speed, and water spray volume, the compaction and moisture content of the granules can be precisely controlled, resulting in smooth, round, and densely structured finished granules with a compressive strength of 15-30N, making them less prone to breakage and clumping during handling and storage. The particle size can be flexibly adjusted between 2-10mm to adapt to different market demands, and the low-temperature granulation feature maximizes the retention of effective components in the raw materials, making it particularly suitable for preserving nutrients in organic fertilizer production.
This process also boasts wide adaptability and ease of operation. It can process various raw materials such as livestock and poultry manure, straw, and urea, covering over 80% of granular fertilizer raw material types, enabling multi-variety production without equipment changes. The equipment has a simple structure and is equipped with a PLC intelligent control system. One-button parameter setting enables automated operation, requiring no professional technicians; even beginners can quickly learn to operate it. Furthermore, the low cost of replacing vulnerable parts and convenient maintenance further reduce operating costs.
In addition, the disc granulation process is energy-saving, consumption-reducing, and environmentally friendly. Relying on the material’s own adhesion and centrifugal force for granulation, energy consumption is reduced by 20%-30% compared to traditional processes. Furthermore, it eliminates the need for large amounts of binders, requiring only a small amount of water spray for efficient granulation. The enclosed design also minimizes dust leakage, aligning with the trend towards green production.
In summary, the disc granulation process, with its comprehensive advantages of high pelletizing rate, superior quality, wide applicability, ease of operation, and low energy consumption, precisely addresses the pain points of traditional granulation methods. It has become an ideal granulation solution that balances practicality and economy, providing an efficient and feasible technical path for various pellet production enterprises.
