is a kind of fertilizer equipment that can be produced without drying and at normal temperature. It is also very convenient to produce and has the characteristics of one-time molding. The defect of this kind of equipment is that the output is relatively low, but you can also order different specifications of extrusion granulation equipment according to your actual production situation.
The structure of roller granulator is relatively simple, and the relative area will be less, which is very suitable for some small fertilizer production enterprises. According to different raw materials, different types of fertilizers can be produced, including various organic fertilizers, compound fertilizers, etc. The fertilizer granulator machine
is a kind of fertilizer production equipment which can be changed flexibly.
Introduction to the characteristics of roller granulator:
- 1) Compared with other methods, it does not need fuel oil, gas and other drying measures.
- 2) There is no need to add additional binder. Steam granulation is the common production method of compound fertilizer in China. Water vapor condenses and crystallizes between the material molecules and acts as an adhesive in the manufacturing process. But in the drying process, the water inside and on the surface of the particles must be driven out, otherwise the fertilizer is easy to stick and agglomerate in the storage process. However, dry granulation does not need additional additives, and only uses the intermolecular force of the material itself, which simplifies the process and reduces energy consumption.
- 3) The investment of granulator machine for fertilizer is low, because the drying process is omitted, and the return ratio is low (accounting for about 15% of the total feed amount of the extruder), the process is simple and the investment is low.
- 4) At present, there are more than 20 kinds of materials successfully used in extrusion granulation: ammonium nitrate, urea, ammonium chloride, calcium nitrate, potassium chloride, potassium sulfate, etc.
