Process and Application Characteristics of Flat Die Extrusion Granulator
Jun 01, 2018

The flat die extrusion granulator adopts a unique conical structure, which can make the two ends of the die and the outer ring of the die plate consistent in line speed, without the dislocation of the wheel and the die, reducing the resistance and reducing the kinetic energy loss. , while extending the life of the mold. In fact, the structural feature is its main difference with similar compression molding equipment.


The flat die extrusion granulator controls the required pressure through the screw center pressure regulating mechanism to ensure a good pressing effect. Its roller uses a large groove width, bearing pressure wear, pressure roller using a number of uniform distribution, smooth operation, while increasing the suppression area, improve production efficiency.


For example, the compression molding of sawdust, straw and other materials requires a lot of pressure, so in the same granulation, briquetting, and rod making equipment, the press wheel part of the flat die extrusion granulator is the central part of the entire equipment. Cone wheel flat die can be arbitrarily increased the pressure roller advantage is unequivocal for other devices.


In order to better understand the flat die extrusion granulator and compare it with other similar equipment, it was found that the flat die extrusion granulator has a longer service life and a lower production cost. Moreover, this model is equipped with a variety of Φ1.5-Φ20mm aperture mold, to adapt to different materials granulation, to achieve better efficiency.


After the pellets produced by the flat die extrusion granulator are in the form of a column, the organic particles can inlay each other to grow up under a certain effect, and it is not necessary to add a binder during granulation. The content of organic fertilizer can be as high as 100% to achieve pure organic material granulation.


The flat die extruding granulator can be sieved after granulation to reduce the energy consumption for drying; and the organic matter after fermentation does not need to be dried, and the moisture content of raw materials can be 20%-40%. In addition, some of its main parts such as flat mold plates and sticks are quenched and tempered with high-frequency quenching to provide corrosion resistance, wear resistance and long service life.
