In the fertilizer production line, fertilizer granulator is an important equipment. Many manufacturers want to know the characteristics of different types of granulators when choosing granulators. Huaqiang Heavy Industry briefly introduces the characteristics of
drum granulator and extrusion granulator, so that bosses can choose equipment according to actual needs.
The advantages of
drum granulator are large production capacity of single equipment, good airtightness, no dust and exhaust gas overflow, easy to set automatic control of feeding and water spraying, long residence time of materials in the cylinder, and high particle strength. At present, large and medium-sized fertilizer production plants all adopt drum granulation. Some plants also connect disc granulator and drum granulator in series for secondary granulation, and the effect is also good.
Extrusion granulators are mainly double-roller, double-roller, and single-shaft types. The shape of the granules is mainly pressed according to the shape of the ball socket on the roller skin. There is a large range of choices at present: pillow-shaped, semi-circular granules, rod-shaped, tablet-shaped, walnut-shaped, flat spherical, and square strip shapes.
The extrusion granulator is a dry granulator, the moisture content of the material is less than 20%, and no additional water is required during the granulation process. After the granulation is completed, there is no need to use a dryer for drying, which saves equipment investment and drying energy consumption.
In fact, in addition to the stock granulator and the
extrusion granulator, there are many other types of granulators, but these two are more common. If you want to know more about fertilizer production, please contact Huaqiang Heavy Industry.
