Ring Die Feed Pellet Machine – Industrial-Grade Pelletizing Solution for Feed and Biomass

The Ring Die Feed Pellet Machine is a high-efficiency pelletizing system designed for large-scale feed mills, biomass fuel plants, and organic fertilizer production lines.
It is capable of producing 2–8 tons per hour per unit, and multiple units can be combined to form a complete automatic feed production line.

This machine is ideal for producing animal feed pellets for chickens, ducks, geese, pigs, cattle, horses, and sheep, as well as biomass fuel pellets and organic fertilizer pellets.
The final pellets are cylindrical, with diameters ranging from 2.5 mm to 12 mm, and the pellet length can be adjusted according to specific requirements.

Ring die feed pellet mill

 1. High Productivity for Continuous and Stable Operation

The ring die pellet mill is built for industrial-scale, continuous production.
Its robust structure, powerful motor, and precision components enable long hours of non-stop operation with stable output.

• High production capacity: Models available with hourly output from 2 to 30 tons or more.

• Efficient compression area: Some models adopt double-layer ring die design, which increases working surface and enhances capacity.

• Consistent operation: Designed for 24-hour production environments such as commercial feed plants or biomass factories.

If you are planning to build or upgrade a large feed pellet production line, the ring die feed pellet machine is your core equipment.

 2. Superior Pellet Quality and High Density

Compared with flat die pellet machines, the ring die system provides greater compression and longer retention time for raw materials inside the die.

This results in pellets with:

• Higher density and better shape

• Smooth surface and uniform size

• Lower powder rate and breakage

• Improved water resistance, especially important for aquatic feed production

These advantages make the machine highly suitable for poultry feed, cattle feed, fish feed, and shrimp feed, ensuring better feed conversion and easier storage or transportation.

 3. Advanced Conditioning and High Degree of Maturation

One of the biggest strengths of a ring die feed pellet mill is its steam conditioning system.
Before entering the pellet chamber, the raw material is cooked and sterilized by high-temperature steam — a process known as conditioning.

Benefits of this system:

• Starch gelatinization: Improves digestibility and enhances flavor for animals.

• Sterilization: Eliminates harmful bacteria and pathogens, improving feed safety.

• Increased binding strength: Enhances pellet durability and reduces fines.

As a result, the feed produced by this machine achieves better palatability, higher digestibility, and greater nutritional value.

 4. High Automation and Stable Performance

The ring die feed pellet machine can be integrated with automatic control systems for intelligent operation.

• Variable frequency drive (VFD): Allows flexible control of feeding speed to match material type and moisture content.

• Automatic lubrication: Ensures smooth roller and die operation, reducing wear and maintenance.

• Standardized maintenance: Components such as rollers, bearings, and ring dies can be easily replaced, with global parts supply available.

This makes it a perfect choice for modern automatic feed processing lines or biomass pellet plants seeking to maximize productivity and reduce labor costs.

Working Principle

The press rollers inside the chamber rotate along the inner surface of the ring-shaped die, pressing the material through the die holes under high pressure.
The extruded material comes out as solid cylindrical pellets, which are then cut to the desired length.

This continuous pressing mechanism ensures high output, uniform density, and long service life of the equipment.

Biomass Materials:
Sawdust, wood chips, rice husk, wheat straw, sugarcane bagasse, palm kernel shell, coconut shell, bamboo dust, and crop residues.

Organic Fertilizer Materials:
Animal manure, compost, organic waste, and plant residues.

Advantages of Ring Die Pellet Mill vs. Flat Die Pellet Mill

Feature	Ring Die Pellet Machine	Flat Die Pellet Machine
Capacity	2–30 tons/h	100 kg–3 tons/h
Best for	Industrial / factory use	Home or small farm use
Pellet quality	High density, smooth surface	Medium density
Conditioning system	Steam conditioning supported	None or optional
Automation	High (VFD + automatic lubrication)	Manual operation
Maintenance	Standardized parts	Simple and low-cost

If your business aims at commercial feed production or large biomass projects, the ring die pellet machine is the optimal choice.

Applications

• Poultry feed production (chicken, duck, goose)

• Livestock feed production (pig, cattle, sheep, horse)

• Aquatic feed processing (fish, shrimp)

• Biomass pellet manufacturing (wood, straw, husk)

• Organic fertilizer pelletizing

With its powerful performance and flexibility, this machine supports custom formulations for different species and purposes.
