The organic matter content can be as high as 100% in the production of the double roller granulator, and the pure organic matter can be granulated. The application of organic particles can inlay and grow up with each other under certain effect, and no binder is needed when granulating. The granules are solid and can be sieved after granulation, reducing boring energy consumption. The organic matter after the fermentation of the organic fertilizer production line does not need to be dry, and the moisture content of the raw material can be 20-40%.
The angle of the pelletizing disc adopts the entire arc structure, and the granulation rate can reach more than 93%. The pelletizing disc is equipped with three discharge ports, which is convenient for continuous production of homework, greatly reduces labor intensity, and improves labor efficiency. The idea is driven by a flexible belt, which can start smoothly, reduce the impact of the buffer, and improve the service life of the equipment. The bottom of the pelletizing disc is reinforced by multiple radiant steel plates, which are durable and never deformed. The thickened, intensified, and consolidated base design does not require ground the foot bolts are fixed and the operation is stable. The main gear of the roller extrusion granulator adopts high frequency quenching, and the service life is doubled. The plate of the roller extrusion granulator is lined with high-strength fiberglass, which is anti-corrosive and durable. This kind of fertilizer granulator machine has average granulation, the characteristics of high granulation rate, stable operation, solid and durable equipment, long service life, etc., are the ideal equipment for the majority of users.
At present, most compound fertilizers must be diversified, but it is impossible to completely replace organic fertilizers. Where possible, the amount of decomposed organic fertilizers should be added as much as possible. Combined application of compound fertilizer and organic fertilizer can improve fertilizer efficiency and nutrient application rate. The application of organic fertilizer not only improves the soil, activates the beneficial microorganisms in the soil, but also saves power and reduces environmental pollution. Using some bio-organic fertilizers can not only avoid the cumbersome process of traditional organic fertilizer production, but also can supply soil with many beneficial microorganisms to activate soil nutrients and reduce crop rotation damage.
Certain special roller extrusion granulator machine for fertilizer has determined the suitable nutrient ratio according to the fertilizer requirements of crops and the fertilizer supply characteristics of the soil. Disc-to-roller extrusion granulators are also difficult to fully meet the different fertility. Therefore, it is necessary to use some elemental fertilizers together according to the practical development status of crops. For example, on the nitrogen-deficient soil, it is necessary to use some nitrogen fertilizer for leafy vegetables that require more nitrogen, and some potassium fertilizer should be used for the watermelon that requires more potassium on the potassium-deficient soil.
