Disc Granulator Machine

In the process of making fertilizer, the disc granulator machine is one of the key equipment to process powder fertilizer into granules. It has characteristics of high granulation rate, high efficiency, low investment, etc. Therefore, combining with other fertilizer equipment, such as compost machine, mixer, crusher, dryer, cooler and so on, you can create a disc granulation line to help you produce higher quality pellets. Whether you want to prepare organic or compound fertilizer.

Why do you need a granulator?

Granulating machine is a kind of industrial professional equipment in fertilizer making, which can turn powder materials into granules. After granulating, the density of the material increases and its unit weight decreases, so the fertilizer is easier to store and transport. In addition, compared with powder fertilizers, granular fertilizers have lower possibility of materials sticking and caking, so you can add some inorganic ingredients to improve fertilizer efficiency. Finally, granulation can prevent separation of material components, making fertilization easier. Therefore most manufacturers usually prefer to make granular fertilizers rather than powdered fertilizers. In a word, granulating machines play an important role in organic fertilizer manufacturing and compound fertilizer production.

How a pan granulator works to make fertilizer into granules

When it comes to the working principle, we have to know the structure of the pan granulator first. The pan granulator conprises a large disc, a scraper, a spray support bar, a reducer, a drive motor, a base, etc.

During the process of granulation, the disc type granulating machine mainly makes use of centrifugal force from pan rotation to achieve the purpose of granulation. First, 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 materials will move upward under the action of the rotation of the disc, and fall due to gravity. In this process, the powder materials will roll and stick to each other and finally formed into round granules. After reaching the predetermined diameter, the granules will be out of the pan to the next procedure.

5 Reasons why so many fertilizer manufacturers prefer to choose pan pelletizer for their fertilizer production plants?

Pan pelletizer is a hot selling fertilizer making machine in SX. From the feedback of our customers, we find there are 5 reasons as follows:

Its granulation rate can reach more than 93%, which means it can make more fertilizer granules you need with the same amount of materials. So you can produce granular fertilizer faster and with less material waste.
The disc of this pelletizer is provided with three discharge ports, which is convenient for intermittent production operations. So it can greatly reduces labor intensity and improves labor efficiency.
The reducer and motor use flexible belt to work start smoothly, slow down the impact force. Moreover, the plate bottom makes use of radiant steel plates to reinforce itself, so that it becomes more durable and never deforms. So pan granulator can offer you service for a longer time.
The scraper can remove the materials attached to the disc body and improve the granulating rate and quality.
The pan pelletizer can be used for various fertilizer preparations, you can make use of it to process cow manure fertilizer, chicken manure fertilizer, NPK compound fertilizer, DAP fertilizer, etc.

How do you control the granules size in pan pelletizer granulation?

In general, 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? Usually, there are two ways to regulate the granules size.

Changing moisture content

First, 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, smaller size; much water, bigger size.

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. Sharp slope, smaller size; slow slope, bigger size. In this way, 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. Among them, SXYZ-1800 is the one with the smallest output, about 0.8-1.2 tons/h. It is an ideal choice for you, if you want to start a small scale fertilizer making. The largest output one is SXYZ-3600, about 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. In addition, they can both be used in producing organic fertilizers or compound fertilizers.

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.


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.


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.


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? In general, 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: For fertilizer processing equipment, material is essential. It is closely related to the service life of your machines. Because most fertilizer materials have serious erosion to equipment. But SX pan pellet machine mainly adopts Q235B boiler steel as manufacturing material, which has high strength and excellent performance in corrosion resistance. In addition, if you need, we can also add a stainless steel lining to further improve the erosion resistance and prolong the service of your disc granulation equipment.

A: Both are no problems. As mentioned above, SX disc granulator machine can granulate not only chicken poop, cow dung, pig waste, mushroom waste, etc but also N/P/K powder, bentonite, zeolite, etc. If you are still not sure, you can contact us immediately for an answer.

A: Of course. In general, 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. For example, for 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. Therefore, you can finish the turning from powder to pellets within 5-8 minutes. But this is a continuous process instead of batch by batch.

A: About 50 mesh. Using this kind of raw material, you can produce fertilizer pellets easier. And with a more beautiful appearance.
