With the rapid development of ecological agriculture, organic fertilizer production equipment is upgrading towards multi-functionality, high efficiency, and high adaptability. The ring die granulator, with its outstanding advantages of high-density columnar pellet formation and dual use as feed and organic fertilizer, breaks through industry application limitations and has become a popular choice for integrated crop-livestock farms and compound fertilizer production enterprises.
The ring die granulator adopts a vertical ring die extrusion structure. The core component, the ring die, uses an alloy carburizing process, resulting in high wear resistance and compressive strength. Combined with an eccentric conical pressure roller, it can automatically adjust the extrusion pressure to ensure uniform material formation. During operation, the material is extruded from the die holes under strong pressure, forming solid columnar pellets. These pellets are then precisely cut by a cutter, resulting in uniform pellet specifications and a neat appearance, meeting the production standards of high-end fertilizers and horticultural manures.
Compared to traditional granulation equipment, ring die granulators offer wider applicability and greater stability. They can produce high-organic-content organic fertilizers, process organic-inorganic compound fertilizers, and are also compatible with feed pellet production, achieving multi-purpose functionality and effectively improving equipment utilization. The equipment requires materials with a moisture content controlled between 20% and 35%, resulting in granules that are less prone to breakage, have a long shelf life, and are suitable for e-commerce sales and long-distance transportation.
Industry experts indicate that the widespread adoption of ring die granulators not only enriches the forms of organic fertilizer products but also reduces equipment investment for farmers and livestock breeders, providing practical equipment support for the circular development of agriculture.
