The double roller granulator
has the characteristics of low energy consumption, high energy saving, low investment, simple operation, and pollution-free equipment emissions. The installation of the double roller granulator needs to be debugged. The correct method should be adopted when debugging. First, The distance between the pressure rollers should not be too small or too large, and should be adjusted within the specified range. Secondly, the pressure cover on the bearing seat side should be prevented from being too loose or too tight, which will cause the shaft roller to shift. The advantages of the roller extrusion granulator in the fertilizer production line
are introduced in detail.
One, the advantages of the double roller granulator
1. Low energy consumption and energy saving roller extrusion granulation is a kind of material granulation at room temperature. Compared with other methods, it does not require drying measures such as fuel and gas.
2. Steam granulation is a commonly used method for the production of compound fertilizer without a binder in my country. After intermolecular condensation and crystallization, steam acts as a binder in the production process. However, in the drying process, the moisture inside and on the surface of the particles must be discharged, otherwise the fertilizer will easily stick and agglomerate during storage. Dry granulation does not require another additive, only the intermolecular force of the material itself, which simplifies the process and reduces energy consumption.
3. The low investment is due to the saving of the drying process, the low rate of return (approximately 15% of the total feed volume of the extruder), simple process flow and low investment.
4. The materials successfully used in extrusion granulation include more than 20 kinds of ammonium nitrate, urea, ammonium chloride, calcium nitrate, potassium chloride, potassium sulfate, etc., and the extrusion granulation process can be flexible in a short time To realize the substitution of product formulas, a set of equipment can produce more than 30 formula products. The double roller granulator is a fertilizer granulator commonly used in npk fertilizer production lines
5. The consumption capacity of extrusion granulation is only electricity, environmental protection has no three wastes emissions, in line with the basic national environmental protection policy, and also in line with the corporate environmental development strategy.
Zhengzhou Huaqiang Heavy Industry Technology Co.Ltd has developed and produced complete set of equipment for the Fertilizer Production Line, NPK Production Line
, NPK fertilizer production Line and BB fertilizer production Line. We have Double Roller Granulator and all kinds of fertilizer granulator.
