Amid the shift to green agriculture, organic fertilizer granulators have become essential equipment for converting organic waste such as livestock and poultry manure and straw into high-quality fertilizer. They not only address the inconvenience of transporting and nutrient loss associated with traditional organic fertilizers, but also improve fertilizer application efficiency, contributing to sustainable agricultural development.

Currently, mainstream organic fertilizer granulators include disc, drum, and roller extrusion types. Disc granulators are suitable for small and medium-sized production operations. Using a rotating disc and a spray system, the material is agglomerated into spheres under centrifugal force, resulting in highly rounded granules. Rotary drum granualtor excel at high-capacity continuous production, with a lifting plate inside the drum constantly turning the material, making them suitable for large-scale organic fertilizer plants. Double roller press granualtors eliminate the need for adhesives and directly compress dry powder into granules through roller extrusion, making them particularly suitable for organic raw materials with high fiber content.

Technically, modern organic fertilizer granulators have undergone intelligent upgrades. For example, a variable-speed granulation system developed by an equipment manufacturer automatically adjusts the speed based on the material's moisture content, increasing the pellet formation rate to over 90%. The use of a constant-temperature heating device solves the problem of insufficient viscosity of organic materials in low-temperature environments, ensuring normal winter production in northern China.

With the advancement of the "fertilizer reduction and efficiency improvement" policy, organic fertilizer granulators are becoming a crucial link between agricultural waste resource utilization and green farming, providing solid equipment support for the large-scale development of organic agriculture.
