The flat die pelleting machine and organic fertilizer ball shaping machine are the golden combination for organic fertilizer pelleting and shaping. Their coordinated operation achieves uniform, rounded, high-strength pellets with a high yield.

The flat die granulator is responsible for forming the pellets. After mixing and conditioning, the material enters the flat die granulator and is extruded by the pressure rollers and flat die to form columnar pellets of varying sizes. At this stage, it is crucial to control the moisture content, feed rate, and die orifice specifications to ensure continuous extrusion without breakage, laying the foundation for subsequent pelletizing.

The extruded columnar pellets directly enter the pelletizing machine for rounding and shaping. Inside the pelletizing machine, the pellets are subjected to centrifugal force and friction, which polishes the edges, gradually making the shape rounder and fuller. Simultaneously, it further densifies the pellets, increasing their strength and reducing breakage and dust. The rotation speed and time of the pelletizing machine must be matched with the output of the granulator to avoid over-rounding or inadequate shaping.

In terms of coordinated control, a linked speed regulation system is adopted to ensure that granulation and rounding speeds are synchronized, preventing material accumulation and separation. A simple screening unit can be installed in the middle, allowing unqualified coarse material to be returned to the granulator for reprocessing, forming a closed-loop production process.

The combination of these two machines significantly improves the quality of the finished product: the granules are round and uniform, have good flowability, and are easy to package, making them suitable for organic fertilizer and compound fertilizer production. Through reasonable connection, parameter matching, and process optimization, continuous and stable production is achieved, increasing the yield, reducing energy consumption, and meeting the high-quality granulation requirements of large-scale organic fertilizer production lines.
