What method does double roller press granulation adopts?
YUSHUNXIN double roller press granulator adopts extruding granulation, which is also known طريقة التحبيب الجاف. كما يوحي الاسم, it mainly relies on the physical extrusion force between the rollers to press fertilizer powder into granules. There is nearly no water involved.
The function of extrusion is to displace the air between particles and make the distance between particles close enough to generate attractive forces. Such as van der Waals forces, adsorption forces, crystal bridges, and inline connections, which can combine the particles together. بهذه الطريقة, you can directly turn dry powder into granules without adding additives (like water) and produce granules at the room temperature without drying. So it can provide you a fertilizer granulation technology with simpler process and lower energy consumption.
How does the double roller granulator work in your fertilizer granules production?
It is necessary for you to understand the working process of double roller granulator, if you want to prepare required fertilizer granules efficiently. على العموم, it contains 4 أجزاء:
- أولاً, when it starts to granulate fertilizer material, electromotor will drive the belt pulley. Then the belt is transmitted to the driving shaft by the speed reducer. So the driving shaft will operate synchronously with the passive shaft, which makes the double roller pellet mill start working.
- ثم, feeding the powder material to the top hopper of the fertilizer granulation machine. The roller sheets will rotate relative to each other. The dry material will agglomerate and becomes a dense and hard mass (cake) under pressure.
- التالي, there are a pair of stirring shafts to break down the pressed fertilizer cake into single granular fertilizer. This is the final fertilizer pellets you plan to produce.
- فضلاً عن ذلك, to endure the fertilizer granulation cake is fully dispersed, we especially equip the double roller extrusion machine with a screen. Which only allows the single granulated fertilizer to pass through.

How to adjust double roller extrusion granulator to improve fertilizer quality?
In the granulation process of using the double-roll granulator, sometimes the particles are not spherical or the powder leaks too much. At that time, you can adjust these two parts of the double roller extrusion granulator to improve fertilizer quality.
Gap between the rollers adjustment
In the process of إنتاج الأسمدة, sometimes it is necessary to increase the output or bite angle. في هذا الوقت, you need to increase the distance between the two compression shafts. Then the distance between the driving shaft and the passive shaft becomes bigger. The steps are as follows:
- Stop the machine and remove the frame above the two bearing seats.
- Adjust the adjustment plate between the two bearing seats to the required thickness.
- The distance between the two rollers cannot make the wheels collide. So you need to keep the minimum between 0.3-1 مم.
Alignment of ball socket
The ball socket is contist of the pits on the surface of the main roller. So if you want to improve fertilizer quality, you must pay attention to axial alignment and circumferential alignment.
The axial alignment has been adjusted during installation
بشكل عام, the possibility of adjustment is not large. If you need to adjust it, you can tighten or loosen the glands on both sides of the passive bearing seat, so that the dislocated sleeve can move and correspond to the active shaft.
The steps of circumferential alignment
أولاً, you should loosen the 6 connecting bolts of the driven gear and the adjustment sleeve, so that they can slightly disengage with each other. Then you can correct the circumferential direction by tightening or loosening the two adjustment bolts with a hand wrench. فضلاً عن ذلك, our engineers have already thought that customers may need to adjust the ball socket when designing the roller granulator. لذلك, they have reserved sufficient adjustment distance. So the dislocation can be adjusted no matter how much the dislocation is. أخيراً, you need to test the adjustment effect. Because the ball socket is too small, you can place a carton board between the two rollers during testing. After rolling, you can know whether the adjustment has achieved the purpose by seeing it. After alignment, you can tighten the 8 connecting bolts.
