Organic fertilizer granulators
The 'new type' organic granulator covers a family of wet-granulation machines designed for high-moisture fibrous organic material, where conventional
Organic material varies in plasticity: fibrous manure and straw form granules by agglomeration, while dry mineral-rich blends need pressure or extrusion. A trial on real material is worth more than any specification table.
Organic binders reduce the water needed, which reduces dryer load and fuel. The binder must be compatible with the declared analysis of the product.
Each route has a working range — typically 25–32% for disc and drum granulation, 8–15% for extrusion. The plant dryer is then sized on that inlet moisture.
The recycle ratio stabilises granule formation; screening and return conveyors are part of the granulation system, not a separate accessory.
Acceptance is measured on size distribution, strength and throughput with your material, not on the machine's nominal rating.
| Route | Inlet moisture | Granule shape | Binder need | Dryer load |
|---|---|---|---|---|
| Disc granulator | 25–32% | Round | Medium | High — large water addition |
| Rotary drum | 25–32% | Rounded, slightly irregular | Medium | High |
| Stirring-tooth | 25–35% | Irregular, strong | Low | High, but less binder water |
| Double-roller extrusion | 8–15% | Cylindrical / flake | Low to none | Very low |
| Flat-die pellet mill | 12–18% | Cylindrical | None | Low |
Notes from our own records on granulation machines for organic material and how wet granulation fits into the production process.
Organic fertilizer is often made from organic waste. By this way, you can both lower cost and decrease organic waste’s pollution on environment. As we all know, we usually convert organic waste into organic fertilizer by composting. Take manure of livestock or poultry as an example, it cannot be used directly. For one thing, manure will automatically ferment and produce heat. The heat will do harm to roots of plants and crops. For another thing, the direct application may cause air pollution because of its obnoxious odors. After composting, fermented organic waste becomes organic fertilizer. In addition, if you manufacture organic fertilizer for sale, you may need further processing. That is to say, you can manufacture granulated organic fertilizer by organic fertilizer granulation machine.
What’s organic fertilizer granulation machine and its working principle? Organic fertilizer granulation machine is also called fertilizer pellet machine. In addition, it is an important part in whole organic fertilizer production line. And it can granulate powdery organic fertilizer into granules. On the one hand, granules are more convenient for storage, transport and application. Meanwhile, you also can add some functional bacteria in granulating process, so as to make bio-organic fertilizer. In addition, you can also add other materials to enhance fertilizer efficiency. Therefore, it is a good choice to granulate organic fertilizer as deep processing.
Working principle of YUSHUNXIN granulation machine In terms of making organic fertilizer pellets, all granulator equipment adopts wet granulation. In other words, certain amount of water or steam is used for making powdery organic fertilizer into pellets. At the same time, other components of granulator also help to granulate organic fertilizer.
What kinds of organic waste can use organic fertilizer granulation machine? YUSHUNXIN organic fertilizer pellet machine is available for various organic waste. Moreover, our granulator is not only widely applicable for different organic waste, but also has multiple types for you to choose. What’s more, the suitable organic waste including:
Notes: All mentioned organic waste shall complete composting. And then you can granulate them.
What kinds of organic fertilizer granulation machines can YUSHUNXIN provide you? As a granulation machine manufacturer, we provide four types organic fertilizer granulator for you. All of them have wide application. And then we will introduce them separately.
Disc granulator Disc granulator is one of our hot sale products. Besides of solid construction, it also featured with high granulation rate 93% and easy operation. In addition, you should pay attention to the quality of organic fertilizer powder. That is to say, you should guarantee that there is no large caking and other materials in the powder. Therefore, you can adopt screening machines to screen fermented organic waste. And you can choose rotary screen machine and vibrating screen machine, which can provide you uniform powder. In addition, disk granulator have many models, whose working diameter ranges from 0.5 m to 3.6 m. On the one hand, the smallest model can be used for laboratory. On the other hand, you can adopt it in large scale fertilizer production line, compound fertilizer or organic fertilizer.
New type organic fertilizer granulator This kind of granulator is our patented product. It granulates powdery organic waste by the inner rotary shaft and steam. Different with disc granulator, new type organic fertilizer granulator belongs to closed granulating process. Therefore, it will not cause dust. Generally speaking, its specification is larger than disc granulator. Therefore, you can use this kind of fertilizer granulator for medium and large scale organic fertilizer production.
Rotary drum granulator Rotary drum granulator also adopts wet granulation. When the main body of rotary drum granulator rotates, rotary cylinder can make powdery organic fertilizer into pellets in virtue of centrifugal force and steam. In addition, the main body of granulator has certain incline angle. By this angle, granular organic fertilizer will successfully enter next stage. What’s more, this kind of granulator is available for making both granular organic fertilizer and compound fertilizer pellets.
Rotary drum stirring granulator As YUSHUNXIN’s patented equipment, rotary drum stirring granulator has stronger functions. In particular, it is equal to the combination of new type organic fertilizer granulator and rotary drum granulator. With the help of steam or water, powdery organic fertilizer gradually become granules under the rotation of main body and stirring of revolving shaft. Organic pellets produced are more compact, which is convenient for transport and storage.
What works should you do before and after granulating? If you want to make high-quality organic fertilizer pellets, you should pay more attention to granulating process and preparation works. High-quality pellets means beautiful appearance, compact structure and uniform size. Besides suitable organic fertilizer granulation machine, in order to make popular organic fertilizer, you should do the following works.
Preparation before granulation In order to make fermented organic waste into uniform fertilizer granules, you should guarantee that no caking and other materials in power. We recommend new type vertical crusher and disc mixer for you. New type vertical crusher is used for crushing large caking in fermented organic waste, so as to produce uniform powder. If you want to increase the function of organic fertilizer, you can add some other elements, such as functional bacteria. And then, you can blend them evenly by disc mixer. After disposal, powdery organic fertilizer will be sent to granulator for granulating.
Works after granulation In order to control the water content of organic fertilizer pellets, you had better deal with them by rotary drum and drying machines. By these machines, the water content of pellets will be decreased so as to achieve standard. In addition, rotary screen machine will be adopted as the next step. Rotary screen machine will separate pellets with unqualified size from qualified pellets. And then conveying equipment will send qualified pellets back for secondary granulating. Meanwhile, qualified pellets will enter next stage. You can directly package the selected granules.
Within limits. Changing binder, moisture and recycle ratio lets a disc or drum machine cover a range of organic formulations, but a line that must switch between living bio-organic product and a mineral blend usually needs separate sections to avoid cross-contamination.
Send 100–200 kg of cured material and we run a granulation trial, reporting achievable size distribution, strength, required binder and the moisture that has to be dried out. That data becomes part of the design basis.
Usually insufficient binder, over-fast drying that creates internal stresses, or insufficient cooling before screening. Granule strength is checked at commissioning and the settings are recorded so the plant can hold them.
As an indication, 25–55 kW per tonne per hour for the granulator itself, plus the conveyors, recycle system and dust extraction. The dryer remains the largest load in the plant.
Tell us the feedstock, the daily tonnage and the product you want to sell. The engineering team replies with the plant configuration, the equipment scope and the information we still need before layout drawings start.
