In the core stage of the bio-organic fertilizer production line, chain crushers and ring die pelleting machines, as key bio-organic fertilizer equipment, have a highly efficient connection that directly determines the molding rate and quality of the granular product. Unlike the initial crushing and fermentation stages of raw materials, these two pieces of equipment focus on fine processing and molding before granulation, and are important supports for achieving large-scale production.
The chain crusher undertakes the task of secondary fine crushing before granulation in the production line. Although the organic fertilizer raw materials have been initially composted after fermentation, some lumps or coarse particles may still remain. If these are directly fed into the granulation stage, it will lead to uneven particle formation and insufficient hardness.
The finely processed raw materials from the chain crusher are then transported to the ring die pelleting machine for molding. As the core granulation equipment in the bio-organic fertilizer production line, the ring die pelleting machine, with its unique ring die and roller structure, processes the raw materials into regular granules through extrusion molding. Its advantages lie in its high molding rate, moderate particle hardness, and adaptability to a variety of composted organic fertilizer raw materials. The resulting granules are not only easy to store and transport but also ensure slow nutrient release. In the entire production line, it forms a seamless connection of “crushing →granulation” with the chain crusher, effectively improving production efficiency.
The synergistic operation of the chain crusher and the ring die pelleting machine demonstrates the advantages of professional equipment matching in bio-organic fertilizer production and provides strong support for standardized and high-quality production in the bio-organic fertilizer production line.
