In the complex process of fertilizer processing, the roller extrusion granulator is like a precise shaper, creating high-quality fertilizer granules with its exquisite "skills".
Raw material preparation is the foundation for the roller extrusion granulator to function effectively. Organic materials need to undergo strict screening and pretreatment to ensure their quality, purity, and stable properties. The fermentation process should be just right to ensure that the materials are fully decomposed, while controlling the humidity to a suitable range to ensure the plasticity during subsequent granulation. The uniform particle size of the crushed raw materials provides a good prerequisite for precise granulation.
When the raw materials enter the roller extrusion granulator, precise shaping begins. The two relatively rotating rollers are the core components, and the grooves on the roller surface are like molds. The raw materials are accurately fed between two rollers under the uniform pushing of the feeding device. As the roller rotates, the squeezing force gradually increases, and the raw material is precisely filled into the groove, following the shape of the groove in every inch. This precise filling process ensures that each particle has a consistent contour in the initial stage.
Under the continuous squeezing force, the raw material is compacted and formed in the groove, and extruded from between the rollers to form a columnar shape. At this moment, the cutting blade system appears, like a highly skilled tailor, accurately cutting columnar materials according to pre-set lengths. Every cutting is precise, resulting in uniform length and size of fertilizer particles produced.
The precision of the roller extrusion granulator is also reflected in the control of fertilizer particle strength. By adjusting parameters such as roller pressure, speed, and raw material formula, it is possible to accurately shape particle strengths that meet different requirements. For fertilizers that require long-distance transportation or long storage time, high-strength granules can be produced; For some application scenarios that have special requirements for particle disintegration speed, it is possible to accurately control the appropriate strength of particles.
In addition, in terms of nutrient retention, the roller extrusion granulator is also precise and excellent. Due to the absence of additional binders, various nutrients in the fertilizer are preserved in their original form, accurately meeting the different nutrient requirements of crops.
The roller extrusion granulator, with its precise control at every stage, carefully shapes every step from raw materials to finished products, providing high-quality fertilizer particles with regular shape, uniform size, suitable strength, and sufficient nutrients for agricultural production. It is truly a precise shaper of fertilizer processing.
