cow dung pellet making machine
RICHI cow dung pellet making machine is designed to process treated cow dung into uniform pellets for organic fertilizer production and biomass fuel applications. We offer different machine configurations and capacities to suit different raw material conditions, pellet requirements, and production goals.
Cow Dung Pellet Making Machine Overview
Fresh cow dung takes up a lot of space and contains a high amount of moisture. Direct transportation and long-term storage can therefore increase handling costs. After processing and pelletizing, the material becomes more uniform and easier to package, store, and transport. With a cow dung making machine, you can turn this waste into a product that can be stored, transported, and sold.
RICHI cow dung pellet making machine compresses treated cow dung between the rollers and ring die to form dense, uniform cylindrical pellets. Depending on the final application, cow dung can be processed into organic fertilizer pellets or biomass fuel pellets.
Next, we will explain the machine in detail, covering its structure, working process, technical parameters, and complete production process.
Capacity: 1-26 T/H
Power: 22-250 kW
Cow Dung Pellet Making Machine Working Principle
The working process of a cow manure fertilizer pellet machine is relatively simple. Once treated cow dung enters the machine, it is fed into the pelletizing chamber and formed into uniform pellets by the ring die, rollers, and cutters.

Cow Manure Pellet Production Line
A cow dung pellet making machine alone is not enough to consistently produce qualified cow dung pellets. The upstream and downstream equipment must also be configured properly. By understanding the complete cow dung pellet production line, you can see how each processing stage works together.
Fermentation
This is the raw material pretreatment stage. If you are producing cow dung organic fertilizer pellets, fresh cow dung must first undergo composting and fermentation to improve the condition of the raw material.
Cleaning
The fermented material then passes through a cleaning screen and permanent magnetic drum to remove impurities such as iron pieces and stones, protecting the downstream equipment.
Drying
This stage adjusts the material condition. Fermented cow dung still usually contains a high amount of moisture, so it enters a drum dryer for further moisture adjustment. The drying process depends on the actual material condition, so a fixed drying time should not be used simply for convenience.
Crushing
Moisture adjustment can cause the cow dung to form lumps. A crusher is therefore used to reduce the material to a suitable size.
The main purpose is to bring the material to a particle size suitable for pelletizing. This also helps improve pelletizing capacity.
Pelletizing
Pelletizing is the core stage of cow dung pellet production. The cow dung pellet making machine forms the material into uniform pellets. You can select the appropriate capacity, ring die size, compression ratio, and other parameters according to your production requirements.
Cooling
The freshly made pellets are around 70-80°C. Cooling equipment reduces the pellet temperature to approximately 3–5°C above room temperature.
Screening
The screening equipment filters out the unqualified particles and then returns them to the crushing or granulation stage, while the qualified organic fertilizer pellets enter the next packaging stage.
Packaging
Qualified organic fertilizer pellets enter the packaging system after screening. Packaging can be configured according to your sales channels and customer requirements. Common options include small bags and big bags. Automatic weighing, bag sealing, and palletizing systems are also available based on the required automation level.

Cow Dung Pellet Making Machine FAQs
Below are some questions customers commonly ask during actual production and equipment purchasing. These answers can help you quickly determine whether a organic fertilizer machine is suitable for your project.
Can fresh cow dung be pelletized directly?
→
No. Fresh cow dung can contain up to 90% moisture, along with stones, other impurities, and bacteria. It is therefore not suitable for direct pelletizing.
What condition should cow dung reach before pelletizing?
Cow dung is better suited for pelletizing after it has been fully fermented and decomposed, impurities have been removed, and its moisture content and particle size have been adjusted to suitable levels.
What pretreatment is needed before cow dung pelletizing?
Fresh cow dung usually needs pretreatment such as fermentation, cleaning, drying, and crushing. Fermentation helps further decompose the cow dung. Cleaning removes impurities such as stones and metal pieces. Drying is carried out according to the actual moisture content to reach a suitable condition for pelletizing. After crushing, the material has a more uniform particle size, which helps maintain stable pelletizing.
Why does the cow dung pellet making machine get clogged during production?
→
When clogging occurs, first check the raw material moisture, fiber length, and feeding stability.
Excess moisture can make cow dung stick to the feeder and pelletizing chamber. Long fibers or large lumps can also interfere with material entering the ring die. In addition, excessive feeding or an improper gap between the ring die and rollers can overload the pelletizing chamber.
Therefore, simply reducing the feeding rate may not solve the problem. Check the upstream drying and crushing conditions, then adjust the feeding rate, roller gap, and pelletizing parameters. The FZLH series uses an anti-bridging feeder and forced feeding system to help maintain continuous material feeding.
Can the pellet machine handle cow dung with large moisture variations?
→
Yes, but the raw material moisture must first be adjusted to a suitable level for pelletizing.
Cow dung moisture varies with farming methods, collection methods, fermentation conditions, and storage time. If today’s cow dung is relatively dry while tomorrow’s is much wetter, direct feeding can affect feeding rate, pellet formation, and pellet strength.
In this situation, the pellet machine alone cannot solve the problem. A drying or mixing adjustment stage is usually needed before pelletizing. The material condition entering the pellet machine should also be controlled according to actual moisture levels. For continuous production projects, we design pretreatment solutions based on raw material variations rather than selecting a pellet machine only from laboratory test conditions.
Why are my cow dung pellets not strong enough and easy to break during transportation?
→
Loose pellets are usually related to raw material moisture, crushing fineness, ring die compression ratio, and roller condition.
If the cow dung moisture is too low, the material may not form stable pellets during compression. Excessive moisture can instead cause sticking, clogging, or unstable pellet formation. Large fibers or lumps in the raw material can also affect compression inside the ring die.
If this occurs, first check the raw material moisture and particle size. Then adjust the ring die compression ratio, roller gap, and other pelletizing parameters according to the material characteristics. If the cow dung is mixed with straw, rice husk, or other materials, the mixing ratio and pelletizing conditions should also be adjusted.
I have a farm with around 100 cattle. Which cow dung pellet making machine should I choose?
→
If you have around 100 cattle, you should not select a pellet machine based only on the number of animals. More important factors include the daily amount of cow dung and the amount that needs to be processed per hour after fermentation, dewatering, and crushing.
For example, if you only plan to process cow dung from your own farm, the FZLH250 may be a suitable starting point. Its capacity is 1–1.5 t/h. If you later plan to collect cow dung from nearby farms or expand your fertilizer production, you can consider the FZLH320 (2–3 t/h) or FZLH350 (3–5 t/h).
The number of cattle is only a reference point. If you can provide your daily cow dung volume, raw material moisture, planned operating hours, and target pellet diameter, we can recommend a more suitable model based on the actual material volume rather than simply the number of cattle.
What after-sales support is included with your cow dung pellet making machine?
→
The complete machine comes with a 12-month warranty. After the warranty period, we provide lifetime technical support and charge only for replacement parts when repairs are required.
For a single machine, we can provide installation and commissioning guidance, operator training, technical support, and spare parts supply. These services help you complete machine installation and learn daily operation and maintenance.
