With the continuous development of science and technology, the demand for agricultural fertilizer is higher and higher. For different crops, different regions and soils, the demand for fertilizer is different. In order to meet the actual needs of crop growth, in NPK fertilizer production line, fertilizer production enterprises should try to plant soil, apply fertilizer, prepare special fertilizer, adopt professional NPK fertilizer production process to produce compound fertilizer with multiple nutrients.
Roller granulator is widely used in NPK fertilizer production line. This kind of fertilizer granulator plays an important role in the production of compound fertilizer. The roller press granulator uses physical extrusion to produce elliptical particles. The roller granulator has greatly promoted the development of extrusion granulation of compound fertilizer and the extrusion granulation process of NPK fertilizer production line.
Production of compound fertilizer granules by rolling granulator
The characteristics of raw materials have an important influence on the granulation effect of roller granulator. The roller granulator can be used for granulation production of ammonium carbide, ammonium chloride, ammonium sulfate, vegetables, ammonium nitrate, magnesium sulfate, magnesium silicate, zinc sulfate, etc., as well as the granulation of NK compound fertilizers such as organic fertilizer and biological fertilizer.
On the other hand, the temperature of raw materials has a great influence on extrusion. In the extrusion process, the friction between the particles will generate heat and increase the material temperature. Generally speaking, the increase of temperature is conducive to the smooth completion of the extrusion process and the strength of the plate. However, too high temperature will also bring adverse effects, especially in the processing of urea based fertilizer materials, too high temperature will make the material adhere to the coil.
The roller granulator designed by Zhengzhou SX fertilizer equipment manufacturer adopts normal temperature extrusion granulation process, which can better maintain the characteristics of raw materials without affecting fertilizer efficiency. In order to avoid fertilizer bonding roller, the roll body of roller granulator was refined with a kind of anti-corrosion, wear-resistant, impact resistant and durable metal.
