New Two-in-One Organic Fertilizer Granulator: An Integrated Solution for Granulation and Mixing

The equipment's key breakthrough lies in overcoming the functional limitations of traditional granulators; through structural optimization and process integration, it combines critical steps—such as pre-mixing, granulation, initial screening, and the crushing of returned material—into one system. Traditional processes require separate operation of crushers and granulators, while the new two-in-one organic fertilizer granulator condenses both processes into a single machine. Through the synergistic cooperation of the two core processes, continuous and automated production from raw materials to finished granules is achieved. The system comprises an integrated main unit, a feeding system, an extrusion-granulation assembly, an internal screening and crushing device, and an intelligent control system. It employs "extrusion plus granulation" dual-forming technology, making it suitable for granulating a wide range of organic raw materials.

The working principle of the new two-in-one organic fertilizer granulator is simple and efficient: after the pre-treated organic raw materials are fed into the main unit through the feeding system, the built-in double spiral stirring component first completes the uniform mixing of raw materials and auxiliary materials, and the mixing uniformity can reach more than 95%. Without the need for material transfer, the mixture undergoes high-pressure forming directly via the extrusion-granulation assembly. The formed granules enter the internal screening device; qualified granules are discharged immediately, while unqualified ones are routed back to the granulation zone via an internal return channel for re-granulation. This results in a stable granulation rate exceeding 95% with zero material waste. Material enters through an inlet at one end of the machine, is continuously propelled by the granulation rotor while interacting mechanically with the casing, and is finally discharged as finished granules from the opposite end.

The core advantages of the new two-in-one organic fertilizer granulator are reflected in multiple aspects. First, the machine is versatile and highly adaptable, capable of flexibly processing a wide range of organic raw materials such as livestock and poultry manure, crop straw, spent mushroom substrate, and medicinal herb residues. Second, its integrated design significantly cuts costs and boosts efficiency; it eliminates the need for coordinating multiple pieces of equipment and handling material transfers, reduces energy consumption by 20% to 30% compared to traditional granulation systems, and keeps material loss below 3%. It occupies only one-third to one-half the footprint of conventional granulation lines, while direct equipment procurement costs are reduced by 30% to 50%. Third, it ensures controllable quality and high added value; the built-in precision granulation mold allows for flexible adjustment of particle sizes between 2 and 8 millimeters, enabling the production of either smooth, spherical granules or high-strength cylindrical ones. The process requires minimal binder additives, thereby maximizing the retention of organic matter and active microorganisms in the raw materials and enhancing the quality and added value of the organic fertilizer.

Embodying the design philosophy of "all-in-one integration and multi-material adaptability," this new two-in-one organic fertilizer granulator precisely meets the urgent need for cost reduction and efficiency improvement among small- and medium-scale producers. It is rapidly becoming the core granulation equipment for organic fertilizer plants, agricultural supply workshops, and large-scale livestock farms.
