The fertilizer granules produced by a disc granualtor exhibit stable overall quality, with outstanding appearance and uniformity; consequently, the machine is a commonly used granulation device in the production of organic and compound fertilizers. The finished granules are round, plump, and highly spherical, featuring smooth surfaces free of sharp edges. This results in an excellent commercial appearance—visually appealing during packaging and application—and ensures high market acceptance. The granule diameter can be flexibly adjusted within a range of 2 to 10 mm; the finished product features uniform particle size with minimal size deviation. After screening, the yield of finished product is high, the volume of returned material is low, and production efficiency remains stable.
The finished granules possess excellent flowability and are resistant to sticking or caking, facilitating easy storage, transportation, and mechanized application. When applied, they scatter evenly, thereby effectively enhancing fertilization results. The granules possess moderate strength; they resist breakage during routine handling and loading/unloading operations, thereby adequately meeting the requirements for storage and transport. Provided that raw material fineness, moisture content, and binder dosage are reasonably controlled, the granulation rate can exceed 90%, and the granules achieve good compactness, making them resistant to crumbling.
However, since disc granulation is a wet granulation process, the moisture content of the finished product tends to be relatively high. Consequently, the process requires the integration of drying equipment; otherwise, the granules are prone to absorbing moisture and becoming soft. Compared to roller extrusion granulation, the hardness of the granules produced by a disc granulator is slightly lower; thus, prolonged exposure to heavy pressure or severe vibration may result in minor fragmentation. Furthermore, the quality of the finished product is significantly influenced by the raw material formulation; insufficient viscosity or uneven fineness in the raw materials can easily lead to issues such as unstable granulation and inconsistent particle sizing.
Overall, the finished products from a disc granulator demonstrate a balanced quality profile, with distinct advantages in terms of appearance and uniformity. This makes the machine well-suited for disc granualtor production produciton lines that demand high aesthetic standards for granules and operate at moderate production capacities. Provided that drying and process controls are properly implemented, the system can consistently produce high-quality finished products.
