Double Screw Extruding Granulator

This pelletizing function of Twin Screw Extrusion Fertilizer Granulator Machine is significantly enhanced by the special flowing mechanical condition and structure inside of the extruding zone. First of all, with the reverse rolling of the double screw, the materials in the extrusion area with repetitive high-speed strong rubbing and frequent shearing to increase the probability of mutual combining between the molecules of the materials. Second, the materials intense colliding and rubbing in extrusion area, make the extrusion pressure rising and keep stable in high pressure state. The temperature of extrusion area high pressure section can rise to above 75 ℃ rapidly. On the one hand, materials pressure and temperature are fully meet the granulating conditions. On the other hand, the strong homogeneous effect changed the molecular structure of materials, so that greatly improve the quality and strength of granules by the heat transferring and high-pressure extruding to get the higher quality fertilizer products.
