Double Rolloer Granulation Line for NPK Fertilizer Production
Roller granulator plays an important role in the granulation stage of NPK production line. Because of its low price, convenient maintenance and low operation cost, the roller granulator is favored by small chemical fertilizer plants.
Raw materials for roller granulator production line
The roller granulator has a wide range of raw materials and can be used in the processing of various nitrogen, phosphorus and potassium fertilizer production lines. The materials that can be used for extrusion granulation are: ammonium bicarbonate, ammonium sulfate, ammonium nitrate, ammonium chloride, ammonium sulfate, urea, calcium nitrate, zinc sulfate, magnesium sulfate, magnesium silicate, phosphorus pentoxide, etc.
NPK fertilizer production line granulation processing
The granulation of roller granulator is a process of reducing the volume and increasing the density of material by mechanical extrusion. In this process, the material is pressed into a narrow gap between a pair of rollers and finally into particles. The roller granulator granulates fertilizer by physical extrusion, which avoids the adverse reaction of fertilizer in production and retains the characteristics of raw materials. At the same time, the temperature of granulation process did not increase significantly, and NPK fertilizer production line could avoid drying and cooling. Therefore, the chemical fertilizer plant saves a lot of energy consumption, which is conducive to the production of small chemical fertilizer plants.
Application of roller granulator production line in small chemical fertilizer plant
Large and medium-sized manufacturing and processing enterprises generally use large drum granulator, which is equipped with hydraulic feeding device, i.e. our hydraulic drum granulator. The hydraulic roller granulator can reduce the backflow of raw materials in extrusion granulation and improve the granulation quality. However, the hydraulic feeding device of the hydraulic roller granulator has high cost, complex structure and inconvenient maintenance. Small fertilizer plants generally choose small roller granulator, which has high cost performance, low price and convenient maintenance. The production line of roller granulator is simple and easy to maintain.
