Double Roller Compound Fertilizer Granulator

The extrusion granulation process of compound fertilizer is the general process of compound fertilizer manufacturing plant, which is of great significance for the user to invest and fully understand the extrusion production of compound fertilizer.

The production process of compound fertilizer extrusion granulation is roughly as follows: raw material proportioning, mixing and mixing, caking and crushing, material granulation, primary screening, particle drying, particle cooling, particle secondary screening, finished product particle coating, and finished product particle quantitative packaging.

Performance advantages of double roll extrusion granulator for compound fertilizer production line:

  1. Reliable operation and low cost. Compound fertilizer double roll extrusion granulator has small power, reliable operation, no three wastes discharge, stable operation and convenient maintenance.
  2. Wide applicability of raw materials for twin roll extrusion granulator. There is no need to add steam granulator to produce other compound fertilizer. Water vapor condenses and crystallizes between the material molecules, which is the result of binder in the process of making. However, in the monotonous process, it is necessary to drive out the water inside and outside the particles, otherwise the fertilizer is easy to stick and agglomerate in the storage process. However, dry granulation does not need other additives, only uses the molecular force of the material itself, which simplifies the process and reduces energy consumption.
  3. The investment of roller extrusion granulator is relatively low, because the monotonous process is omitted, the return material ratio is low, the technical process is simple and the investment is low.
  4. The material composition of the double roll extrusion granulator is active. There are more than 20 kinds of materials successfully used for kneading and granulation at that time: ammonium nitrate, urea, ammonium chloride, calcium nitrate, potassium chloride, potassium sulfate, etc. In addition, extrusion granulation technology can complete the conversion of commercial formula in a very short time. A set of compound fertilizer production line equipment can produce more than 30 kinds of products.
