What method does double roller press granulation adopts?
YUSHUNXIN double roller press granulator adopts extruding granulation, which is also knownطريقة التحبيب الجاف. كما يوحي الاسم, it mainly relies on the physical extrusion force between the rollers to press fertilizer powder into granules. لا يوجد ماء تقريبًا.
double roller prlletizer working principle
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, أنه يحتوي على 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.

What kind offertilizer granulescan double roller pelletizer process?
When you want to buy a properfertilizer granulating machine, it is necessary to know what materials can the machine dispose of. Is it designed for compound fertilizer pellets making? Can we produce granular organic feritilizer with the powder pelletizing machine?
Compound fertilizer granules production
Initially, the double roller extrusion granulator is dsigned formaking chemical fertilizer pellets. لذلك, it is suitable forzinc sulfate, كبريتات البوتاسيوم (إجراءات التشغيل القياسية), كلوريد البوتاسيوم, ammonia chloride, ammonia sulfate, magnesium sulfate, sodium chloride, إلخ
animal manure waste used in organic fertilizer production
Organic fertilizer pellets making
But in 2010, YUSHUNXIN upgraded the roller extrusion pellet machine. لذا, now, it can alsomake fertilizer granules from organic compost. Whether it is chicken manure compost or cow dung compost, إلخ. لكن, because of dry granulation employment, your material water content must be lower than 20% before fed into the roller extrusion machine.
Can the roller press machine granulate phosphate rock powder?
بالطبع. كما ذكر أعلاه, if keeping the moisture of raw materials at 5%-20%, double roller granulating machine can make granules from almost all powder materials. لذلك, it is also an ideal choice forphosphate fertilizer granule making, snow melt agent granulation, bentonite pellets production, إلخ.

Is there roller granulation line for large-scale fertilizer production?
فضلاً عن ذلك, for these commercial fertilizer extruded granules manufacturers, there are also quality supporting equipment to achieve continuous, high-efficiency fertilizer production.
A typicalroller extrusion granulation lineincludes batching equipment, grinders, mixing system, roller press granulator, screening machine, coating unit, and automatic packing system. The dry pressing granulation process eliminates the need for drying and cooling equipment, significantly reducing energy consumption and operational cost. Depending on configuration and automation level, the dry granulation line price usually falls between USD 80,000 and USD 300,000. لكن, with reasonable design, it can support fertilizer granulation plant setup of 1 t/h to 20 ذ. لذا, it suitable suitable for both small and large fertilizer granules making projects.

How long can double roller pressing granulator work?
How long can double roller pressing granulator work is another touchstone for the quality of a fertilizer pelletizer. And it is closely related to the double roller pellet machine manufacturing materials. على العموم, YUSHUNXIN double roller pressing granulator is made of 3 types of material.
Roller sheet with 20CrMnTi steel material
ال main bodyمادةusually adopts high quality boiler steel Q235, which has characteristic of good welding performance and certain alkali corrosion resistance and oxidation resistance.
For theroller sheets material, you can choose to use 20CrMnTi or 4Cr13 stainless steel alloy according to your needs. The former has an economical price, the latter has a better performance in erosion-resistance.
على العموم, the machine can work 8-10 hours per day and provide service for several decades years. But the roller sheet is a wearing part, you need to change it every six months to one year. You need to pay attention to regular maintenance. Proper maintenance can prolong its service life.
Can YUSHUNXIN offer me replacement roller sheets for the dry extrusion granulation equipment?
بالطبع. As a equipment manufacturer for turnkey fertilizer making projects, with a $1,000-$2,000 payment, YUSHUNXIN will offer quality replacement parts for the double roller granulator.
بالإضافة إلى ذلك, also components of bearings, motors, couplings, screens, إلخ. ما هو أكثر من ذلك, you can spare parts of all equipment in the whole double roller granulation process. Such as sieving screen, crushing blades, mixing shafts and so on. Come to get details now!

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. في ذلك الوقت, you can adjust these two parts of the double roller extrusion granulator to improve fertilizer quality.
Gap between the rollers adjustment
In the process ofإنتاج الأسمدة, sometimes it is necessary to increase the output or bite angle. At this time, 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.
