Disc granulators are classic wet granulation equipment in the fertilizer industry. They rely on the rotation of the disc to roll the material into spheres, producing round, dense granules with high nutrient uniformity. Suitable for compound fertilizer production with strict requirements on finished product appearance, especially for large-scale production in medium to large-sized fertilizer plants.

Core compatibility: High-concentration NPK ternary compound fertilizers can be processed, including general-purpose balanced, high-nitrogen growth-promoting, and high-potassium fruit-enlarging types. By controlling the rotation speed and moisture content, nitrogen, phosphorus, and potassium raw materials and auxiliary materials can be fully integrated, producing 2-4mm regular granules that are not easily broken and have balanced nutrients, meeting the fertilizer needs of large-scale field crops such as wheat, rice, and corn.

Secondly, disc granulators are suitable for functional compound fertilizers, including those containing active ingredients such as humic acid, amino acids, and seaweed extract. The wet process is gentle and without high pressure, preserving the active substances and locking in fertilizer efficacy. Suitable for granulating special fertilizers for improving the quality of fruits, vegetables, and cash crops.

It is also an ideal base equipment for slow-release/coated compound fertilizers, producing smooth, moderately hard, and fine powder without sharp edges, allowing the coating agent to adhere evenly and significantly improving the coating quality of sulfur-coated and resin-coated slow-release fertilizers. It is a core pre-processing equipment for slow-release fertilizer production.

In addition, the disc granulator can also process low-concentration compound fertilizers and micronutrient compound fertilizers, with high pelleting rate, easily adjustable parameters, and strong stability, making it a cost-effective and preferred equipment for large-scale compound fertilizer production.
