What are the advantages of fertilizer roller extrusion granulator?
1. Compared with other granulator methods, the fertilizer double-roll extrusion granulator does not require drying measures such as fuel and gas, and has lower energy consumption and energy saving. It is a kind of material granulation at room temperature.
2. Steam granulation is a commonly used compound fertilizer production method without binders in my country. After intermolecular condensation and crystallization, steam acts as a binder in the production process. However, during the drying process, the moisture inside and on the surface of the granules must be drained, otherwise the fertilizer will easily stick and agglomerate during storage. Dry granulation does not require another additive, but only uses the intermolecular force of the material itself, which simplifies the process and reduces energy consumption.
3. The low investment of the double-roll extrusion granulator is due to the saving of the drying process, the low rate of return (accounting for about 15% of the total feed amount of the extruder), the simple process flow, and low investment.
4. There are more than 20 kinds of materials successfully used in extrusion granulation, such as ammonium nitrate, urea, ammonium chloride, calcium nitrate, potassium chloride, potassium sulfate, etc., and the extrusion granulation process can be flexibly processed in a short period of time. Realize the substitution of product formula, a set of equipment can produce more than 30 formula products.
5. The consumption capacity of the extrusion granulator is only electricity, and there is no three-waste discharge for environmental protection, which is in line with the basic policy of environmental protection.
