In the process of organic fertilizer granulation, the roller extrusion granulator relies on strong pressure to shape organic fertilizer particles with high strength.
The pre treated mixed organic fertilizer material is continuously fed into the extrusion granulator. The pressure device inside the granulator begins to function, exerting tremendous pressure on the material. Under strong pressure, materials are forced to pass through mold holes of specific shapes. At the moment when the material is extruded from the mold, a columnar shape is formed. Subsequently, the cutting device will precisely cut the columnar material into particles of appropriate length according to the preset length.
The extrusion granulation method produces organic fertilizer particles with significant characteristics of high density and strength. This is because during the high-pressure extrusion process, the distance between material molecules is greatly compressed, and the internal structure of particles becomes tighter. High strength particles perform well during storage and transportation, able to withstand bumps and collisions, and are less prone to breakage and pulverization. This effectively ensures the quality and nutrient content of fertilizers, whether it is long-term storage or long-distance transportation, it can maintain the integrity of particles and provide users with stable and reliable products.
Another major advantage of the roller extrusion granulator is the precise control of particle shape and size. By changing different molds, operators can produce organic fertilizer particles of various shapes and specifications as they please, such as cylindrical, spherical, sheet-like, etc. This flexibility fully meets the diverse needs of different users and markets. For example, some special agricultural planting scenarios or horticultural cultivation may have specific requirements for the shape and size of fertilizer particles, which can be easily handled by extrusion granulators.
In addition, the roller extrusion granulator has high production efficiency and can work continuously and stably, producing a large amount of organic fertilizer particles per hour. It also has strong adaptability to raw materials, whether it is organic materials with high viscosity or raw materials with high fiber content, they can smoothly complete the granulation process in the extrusion granulator. The extrusion granulator provides a solid guarantee for the production of high-quality and diversified organic fertilizers with its unique granulation method.
