In the process of fertilizer manufacturing, the disc granulator machine is one of the key equipment to process powder fertilizer into granules. Because wet granulation method adoption and compact design, it has characteristics of high granulation rate, low investment, wide granule size, etc.. En outre, combining with corresponding fertilizer equipment, such as compostor, mixer, broyeur, séchoir, cooler and so on. You can create a disc granulation line to help you produce higher quality fertilizer pellets, whether it is organic or compound.
How a pan granulator works to make fertilizer into granules?
When it comes to the working principle, il contient 2 parties. Wet granulation methodand the disc rotation. The former makes us of liquid cohesion to facilitate fertilizer powder granulation. While the latter generateforce centrifuge, which make powder roll together and form into pellets. The whole process is as follows:
D'abord, the processed powder materials will be transported into the disk and added with some water.
After the pan granulator is set in motion, the disc will be driven by transmission devices.
Then the fertilizer materials will move upward under the action of the rotation of the disc, and fall due to gravity.
Dans ce processus, the powder fertilizer will roll and stick to each other and finally formed into round fertilizer granules.
After reaching the predetermined diameter, the granulated fertilizer will be out of the pan to the next procedure.
Its granulation rate can reach more than 93%, This means that you can make more fertilizer granules with the same amount of powder materials feeding. So you can turn powder into fertilizer pellets faster and with less material waste.
Using pan pellet machine, you can prepare granular fertilizer with 1-8 mm diameter easily. You can regulate the fertilizer pellet size freely without extra parts replacement and auxiliary machine.
While pelletized fertilizer discharge, the machine can granulate left powder material and new feeding. À savoir, the disc fertilizer granulation process is continuous and not batch by batch.
D'abord, the disc for fertilizer granulation adopts durable Q235 carbon steel. And the plate bottom makes use of radiant steel plates to reinforce itself, so that it becomes more durable and never deforms. De plus, we also design scraper to remove the materials stick to the pan pellet equipment to reduce the erosion to equipment. So pan granulator can offer you service for a longer time.
How do you control the granules size in pan pelletizer granulation?
En général, fertilizer production suppliers also have different requirements in granules size. And they may want to change the size of their fertilizer pellets in the future. So how to regulate the particle size with disc granulator machine? Généralement, there are two ways to regulate the granules size.
Changing moisture content
D'abord, you can change the pellet size by controlling the water content, and the water spray system can help you control the raw material moisture easily. Less water, taille plus petite; beaucoup d'eau, plus grande taille.
Adjusting disc angle
And another solution to this problem is regulating the pan slope angle. You can adjust the angle between 35 degrees and 55 degrees to regulate the final granules size. Pente aiguisée, taille plus petite; pente lente, plus grande taille. De cette façon, you can produce particles of the diameter you need within 1-8mm.
Which type of disk pelletizers is suitable for your fertilizer pellet making?
It is common that different customers have different needs and requirements in production. As a professional and considerate supplier, we design various types of disk pelletizers for you. Whether you have a small, medium or large fertilizer production line, whether you want to produce organic or compound fertilizers, they can meet your needs.
Parmi eux, SXYZ-1800 is the one with the smallest output, à propos 0.8-1.2 tons/h. It is an ideal choice for you, if you want to start asmall scale fertilizer making. The largest output one is SXYZ-3600, à propos 4-6 tons/h, it is suitable for the medium scale fertilizer production line. If you need larger scale production, you can increase the number of pan granulators to expand the output. En outre, they can both be used in producing organic fertilizers or compound fertilizers.
Details technology parameters of pan granulation machine:
Enfin, the price of disc granulator machine is an item most customers pay attention to. And it is a major factor in determining whether customers are willing to buy this fertilizer granulation machine. The price of disc granulator on the market is about 1,000 dollars/set to 16,000 dollars/set in 2025, and varies with its capacity and configuration. If you want to know detail price of disc pelletizer you need, Vous pouvez nous contacter.
How to use disc granulator to produce granular fertilizer?
Start up
Before starting up, check whether the reducer is filled with gear oil and whether the rotation direction of the disc is correct.
Operation
After pressing the start button, the host starts, and observing whether the equipment is running normally, whether there is vibration, and whether the rotation is stable.
Feeding
After the equipment is running normally, you can add composted material and water.
Granulation adjustment
After feeding, you can adjust the angle of the disc according to the requirements so that the granules can reach the required size.
Granulation
After adjusting the angle of the disc, the material will be processed into the required granules.
Common FAQ about disc granulator
Besides the above information, you may still want to know more about pan pellet equipment. There are some common FAQs about disc granulator we summarize from our past customers’ feedback for your reference.
A: Before disc granulation, you need to make sure the raw material moisture content about 30%. Because in this case, powdery fertilizer materials can combine with each other to form into pellets effectively. Then what is the water content of the fertilizer pellets after pan granulation? Can it be below 10%? It means a low possibility of sticking and easier transport and storage? En général, the fertilizer granule moisture content is about 20% after disc pellet making. But you can use rotary drum dryer to reduce the granule water content to below 10%.
A: Bien sûr. Comme mentionné ci-dessus, YUSHUNXIN pan pellet machine usually adopts Q235 carbon steel. Mais, in order to fully meet your requirements, there is also disc granulation machine with stainless steel lining to further improve the erosion resistance and prolong the service life. Additionally, you also can choose customized disk granulator with spray design, power, etc..
A: Both are no problems. Comme mentionné ci-dessus, SX disc granulator machine can granulate not only chicken poop, bouse de vache, déchets de porcs, gaspillage des champignons, etc but also N/P/K powder, bentonite, zéolite, etc.. If you are still not sure, you can contact us immediately for an answer.
A: Bien sûr. En général, a pan granulation can process 1-6 tons of pellets per hour for you. For larger scale organic and chemical fertilizer production, you can increase the number of disc granulation machines. Par exemple, pour 10 t/h organic fertilizer production line, you can use two SXYZ-3600 pan pelletizers (As shown below). Or buying a three pan granulation system for your 15 – 20 t/h chemical fertilizer production (As shown below).
A: 5-8 minutes. This granule making equipment adopts wet granulation method. Under the help of water, powder material will combine with each other more quickly and effectively. Donc, you can finish the turning from powder to pellets within 5-8 minutes. But this is a continuous process instead of batch by batch.
