With the scaling and intelligent development of the livestock industry, animal feed pellet production line has become a key factor for industry upgrades. This article introduces industry trends, the selection of pelleting systems for feed production plants of different scales, and a comparison between ring die and flat die systems, helping companies optimize production capacity, energy efficiency, and pellet quality.
Overview of Animal Feed Pellet Production Line
The feed pellet production line is a core equipment in modern livestock farming, enhancing production efficiency and feed quality.
Basic concept of feed pellet production line
- A feed pellet production line is a continuous system composed of raw material grinding, ingredient mixing, pelleting (flat die or ring die), drying, cooling, sieving, packaging, and automatic conveying.
- This system is suitable for poultry, livestock, aquaculture, and specialized functional feeds.
- Through pelleting, pellet density typically ranges from 1.1–1.3 g/cm³, and the pelletizing rate can reach 85–95%, ensuring nutritional uniformity and storage stability.

Value of production line in feed processing
- Pelletized feed can improve feed conversion rate by 5%–10%, facilitate automatic feeding and long-distance transport, while reducing dust loss.
- Modern animal feed pellet production line typically features PLC control systems for automated operation and energy optimization, improving energy efficiency by approximately 15%–20%.
Industry data shows that ring die and flat die systems have advantages in terms of pelletizing rate, energy efficiency, and maintenance cycles. The specific choice should be based on production volume, raw materials, formulations, and operating models, rather than an absolute judgment of which is better.

How to Choose Between Ring Die and Flat Die for Different Scale Feed Plants
In feed plant design, the pelleting system is a critical factor affecting production efficiency, energy consumption, formula compatibility, and overall feed pellet production line cost. Below is a selection framework based on three typical scenarios for engineering design.
1. New Feed Plant
Applicable scenario: 1–20 t/h new, standardized animal feed processing plant.
- (1) Production organization
- Ring die lines provide approximately 30%–50% higher stability during continuous operation (industry average), suitable for industrial-scale continuous production.
- Flat die lines are better suited for intermittent, small-batch production, with peak output fluctuations of around 20%–30%.
- (2) Finished pellet performance
- Ring die line: Pelletizing rate is 15%–30% higher than flat die, with complete pellet integrity increased by around 20% for high-starch or high-fat formulas, and density improved by 10%–15%.
- Flat die line: Throughput for coarse fiber raw materials is about 20% higher than ring die, but pellet uniformity fluctuation can reach 15%–25%.

- (3) Energy efficiency and scalability
- Ring die line: Unit energy consumption is 10%–25% lower than flat die, with optional integration of steam conditioning, automatic lubrication, and roller preheating modules.
- Flat die line: Lower initial investment but limited scalability; adding automation modules may increase total investment by 15%–20%.
ABC Machinery can provide comparative design solutions between ring die and flat die lines based on feed mill plant production scale, raw material characteristics, and future expansion needs, ensuring pelleting system configuration aligns with new plant positioning while optimizing pelletizing rate, energy efficiency, and maintenance strategy.
2. Expansion of Existing Production Line
Applicable scenario: Feed plants with some existing animal feed pellet production line equipment, aiming to increase capacity or introduce new feed varieties.
- (1) Capacity increase
Ring die lines integrate well with existing grinding and mixing systems, improving post-expansion output stability by around 25% and reducing animal feed making machine downtime by 20%–30%.
- (2) High-fiber products
- Flat die lines: Straight extrusion better handles high-fiber materials like straw and grass, reducing blockages by about 30%, but mold lifespan is 40%–50% shorter than ring die.
- Ring die lines: High-fiber feed processing requires proper conditioning and die matching; otherwise, pellet integrity may drop by 10%–15%.
- (3) System compatibility
Feed plant expansions should evaluate steam conditioning capacity, plant energy, electricity, and logistics to meet different pelleting requirements.
