Alfalfa Pellet Machine
Designed for alfalfa and other high-fiber forage materials, the RICHI alfalfa pellet machine produces feed pellets, biomass fuel pellets, and organic fertilizer pellets, and is widely used in farms, feed processing, biomass energy, and agricultural resource recycling.
Why are more and more enterprises choosing alfalfa pellet production?
Alfalfa is one of the most widely cultivated and highly valuable premium forages globally. It is rich in high-quality protein, amino acids, vitamins, and minerals, and is widely used in the feeding of dairy cows, beef cattle, sheep, goats, and horses. With the development of large-scale farming and international forage trade, the limitations of traditional bulk alfalfa in transportation, storage, and commercial sales have gradually become apparent.
Due to the large volume and low bulk density of bulk alfalfa, long-distance transportation costs are high. It is also prone to powdering and nutrient loss during loading, unloading, storage, and feeding. Through pelleting, loose forage can be compressed into high-density pellets. While preserving nutritional value, this process improves storage and transportation efficiency, reduces logistics costs, and meets the needs for mechanized packaging, automated feeding, and standardized sales.
Currently, alfalfa pellets are widely applied in fields such as ruminant feed, forage trade, biomass fuel, and comprehensive utilization of agricultural resources. As the global demand for premium forage products continues to grow, more and more pastures, feed enterprises, forage processing plants, and investors are launching professional alfalfa pellet production projects to enhance product competitiveness and expand into broader markets.
RICHI CZLH Series Alfalfa Pellet Mill
The alfalfa pellet mill is equipment specifically designed to press alfalfa hay, alfalfa powder, and other high-fiber forages into pellets.

Key Structures Determining Alfalfa Pelleting Performance
The stable production of high-quality alfalfa pellets relies on rational equipment structural design. During the alfalfa pelleting process, core components—including the ring die, roller, feeding system, and transmission system—are respectively responsible for material feeding, compression molding, and power transmission. Their structural design directly affects pellet density, forming rate, equipment energy consumption, wear, and continuous operation capability.
Targeting the pelleting characteristics of high-fiber forages, RICHI has optimized the configuration of key components to enhance the equipment’s adaptability to different raw materials and overall processing efficiency.
① Feeder
② Ring Die
③ Roller
④ Gear Drive
⑤ Conditioner
⑥ Cutter
① Feeder
Adopting variable frequency feeding, the feed speed can be adjusted according to the pelleting load.
This ensures continuous and uniform entry of alfalfa raw materials into the pelleting chamber, reducing load fluctuations caused by feeding variations.
② Ring Die
The ring die is the most critical wear part of the alfalfa pellet mill. Its compression ratio, die hole structure, and machining accuracy must be selected based on the characteristics of alfalfa fiber.
Different configurations correspond to different pellet density, forming rate, and capacity performance.
③ Roller
Alfalfa has long fibers and strong resilience. The roller needs to continuously press the raw material into the ring die holes to fully compress the fibers and form stable pellets.
The coordination between the roller and the ring die directly affects the material compression effect. Improper coordination can easily lead to problems such as reduced output, loose pellets, or die hole blockage.
④ Gear Drive
During the alfalfa pelleting process, the equipment needs to continuously withstand significant extrusion pressure and load changes.
The direct-coupled gear transmission can stably output torque and maintain stable ring die speed under high-load conditions. This reduces uneven pelleting or equipment impact caused by power fluctuations.
⑤ Conditioner
For alfalfa raw materials with large moisture fluctuations or long fibers, the conditioner adjusts the material state before pelleting.
It ensures a more uniform distribution of moisture and temperature, providing suitable processing conditions for subsequent compression.
⑥ Cutter
The cutter is installed at the discharge end. After the pellets leave the ring die, the cutter completes the fixed-length cutting.
By adjusting the distance between the cutter and the ring die, alfalfa pellets of different lengths can be obtained, meeting the different specifications required for feed, fuel, and organic fertilizer.

Through proper raw material crushing, mixing, and pelletizing processes, different types of forage can be converted into pellets with uniform density and easy storage and transportation.
This improves the utilization of fiber resources and meets the needs of ruminant feed production, commercial forage processing, and agricultural waste recycling.
Working Principle of Alfalfa Pellet Mill
The pelletizing process of the alfalfa pellet mill is primarily accomplished through the coordinated operation of various internal systems. From the entry of raw materials into the equipment, the feeding, transmission, pressing, and cutting mechanisms work continuously according to the preset process, enabling the alfalfa material to undergo compression, molding, and pelletization step by step. The specific working process is as follows:
1.
Material Feeding
The crushed alfalfa meal enters the pellet mill through the feeding system. Upon entering the pelletizing chamber, it is evenly spread over the surface of the ring die, preparing for the compression molding.
2.
Alfalfa Compression and Pellet Formation
As the ring die rotates, the press rollers continuously force the alfalfa material into the die holes. Under high pressure, the loose alfalfa fibers are compressed and bound together, forming columnar pellets with a specific density.
3.
Pellet Cutting and Size Adjustment
The alfalfa columns extruded from the ring die are cut by the cutting knife to form pellets of uniform length. By adjusting the cutting knife clearance and replacing dies of different specifications, alfalfa pellets of various sizes can be produced.
4.
Pellet Discharge
The formed alfalfa pellets are discharged from the outlet of the pellet mill and enter the collection or subsequent processing workflow.

Applications of Alfalfa Pellets
Alfalfa products processed by pelleting feature excellent storability and convenient transportation. They can be applied to animal feed production and biomass energy utilization based on different needs. Currently, alfalfa pellets are primarily applied in the following two fields.
Animal Feed Pellets
Alfalfa pellets are a common form of forage feed, mainly used for raising ruminants such as dairy cows, beef cattle, sheep, and horses. After pelleting, alfalfa is easier to package, transport, and mechanize feeding, making it suitable for large-scale ranches, feed mills, and forage processing enterprises.
Alfalfa pellets can be used alone as roughage, or mixed with corn, soybean meal, and other forages to produce animal feed products with different formulations.
Biomass Pellets
Alfalfa and other grass raw materials can also be processed into biomass fuel pellets for energy utilization. After pelleting, the volume of the forage is reduced and the density is increased, facilitating long-distance transportation and centralized storage.
Alfalfa fuel pellets can be applied in scenarios such as biomass boilers and heating systems, providing an additional utilization method for regions rich in forage resources. Meanwhile, for the large amount of grass resources generated in some agricultural areas, pellet processing also helps achieve more efficient resource conversion.
Complete Alfalfa Pellet Production Line
The fiber length, moisture content, and processing state of alfalfa raw materials directly affect the pellet production results. Therefore, a complete alfalfa pellet production line needs to be configured with corresponding processing stages based on the characteristics of the raw materials, including grinding, drying, pelleting, cooling, screening, and packaging, ensuring that alfalfa raw materials in different states can be smoothly processed into qualified pellet products.
RICHI can design alfalfa pellet production solutions ranging from 0.5 to 40T/H based on customers’ raw material conditions, output requirements, and end-product applications, helping customers build forage pellet processing projects tailored to their specific needs.
