Pellet mill vs extrusion line: choosing the feed mill equipment
Compare pellet mill and extrusion feed mill equipment before a feed mill project is quoted: process, applications, capacity, product range, floating vs sinking feed, micro-pellets, energy, CAPEX and OPEX.
Short answer · reviewed September 2026
Should the project use a pellet mill or an extrusion line?
Use pelleting when the product range is mash, pellets and crumbles for poultry, swine or ruminants. Use extrusion when the product must float, carry high fat inclusion, hold water stability or be produced as micro-pellets — typically fish and shrimp feed. Extrusion costs substantially more in CAPEX and drying energy, so the product specification, not the equipment preference, should decide.
When pelleting makes sense
- Poultry, swine and ruminant feed in mash, pellet and crumble form
- Sinking products where water stability is not a requirement
- Lower capital budget and simpler thermal infrastructure
- High tonnage of a limited number of recipes
When extrusion makes sense
- Floating or slow-sinking aquafeed
- High fat inclusion beyond what pelleting tolerates
- Micro-pellets for shrimp and fish fry
- Higher starch gelatinisation and digestibility requirements
Poultry feed requirements
Pelleting with crumbling for starter phases is standard. The commercial priorities are pellet durability at the feeder, throughput per recipe and consistent particle size after grinding.
Fish feed requirements
Extrusion with drying and coating, across several pellet diameters as fish grow. Buoyancy control and oil absorption capacity are the defining process requirements.
Shrimp feed requirements
Ultra-fine grinding, micro-pellet forming and water stability over extended immersion. Shrimp feed is the most demanding common product on both grinding and dosing accuracy.
Floating vs sinking feed
| Property | Floating (extruded) | Sinking (extruded or pelleted) |
|---|---|---|
| Process | Extrusion with expansion control | Extrusion at low expansion, or pelleting |
| Feeding observation | Intake visible at the surface | Intake not directly observable |
| Typical species | Tilapia, catfish, carp (surface feeders) | Shrimp, bottom feeders, some marine species |
| Energy per tonne | Higher (drying) | Lower to moderate |
Micro-pellets
Micro-pellets require fine grinding, precise forming and gentle handling to limit fines. Both extrusion and specialised pelleting routes exist; the choice depends on target diameter, water stability and volume.
Energy use
Pelleting consumes steam for conditioning and electrical energy at the pellet mill. Extrusion adds preconditioning steam, extruder motor load and a dryer that is usually the largest thermal consumer in the plant.
CAPEX comparison
| Item | Pellet line | Extrusion line |
|---|---|---|
| Grinding | Standard hammer mill | Fine or ultra-fine grinding |
| Thermal processing | Conditioner + pellet mill | Preconditioner + extruder |
| Drying | Not required | Dryer required — major capital item |
| Coating | Optional post-pellet liquid application | Vacuum or atmospheric coater |
| Relative capital cost | Lower | Substantially higher |
OPEX comparison
| Cost line | Pellet line | Extrusion line |
|---|---|---|
| Electrical energy per tonne | Moderate | Higher |
| Thermal energy per tonne | Conditioning steam | Conditioning plus drying — dominant |
| Wear parts | Dies, rollers | Screws, inserts, dies, knives |
| Operator skill requirement | Moderate | High |
Product quality comparison
Pelleting is judged on durability and fines; extrusion is judged on buoyancy control, water stability, oil retention and uniform moisture after drying. Each requires a different quality control setup.
Supplier selection checklist
- Guaranteed capacity for each product family, not an average
- Dryer sizing basis and moisture uniformity commitment (extrusion)
- Durability or water stability guarantee with a named test method
- Energy consumption per tonne at guaranteed capacity
- Wear part cost over two years

Pellet mill vs extrusion line buyer decision guide
Short answer: let the product decide. Pelleting suits mash, pellets and crumbles for poultry, swine and ruminants; extrusion suits floating or water-stable aquafeed, high fat inclusion and micro-pellets. Then ask every supplier to quote the same product list, capacity basis and quality test, and compare guaranteed capacity, energy per tonne, wear parts and landed cost — not the machine price alone.
Pelleting line vs extrusion line
Many mills run both; quote each against the products it must actually make.
| Question | Pelleting line | Extrusion line |
|---|---|---|
| Typical products | Poultry, swine and ruminant feed as mash, pellets and crumbles. | Floating or slow-sinking fish feed, shrimp feed, micro-pellets, high-fat products. |
| Main process items | Conditioner, pellet mill, cooler, crumbler. | Preconditioner, extruder, dryer, coater, cooler. |
| Capital and energy | Lower capital; conditioning steam and pellet-mill power. | Substantially higher capital; dryer is usually the largest thermal consumer. |
| Quality measured by | Pellet durability and fines. | Buoyancy control, water stability, oil retention and moisture uniformity. |
| Trade-off | Simpler and cheaper, but limited for floating or high-fat products. | Wider product capability, at higher cost and operator skill. |
Quote, specification and TCO checklist
- Product list with diameters and form for each product family, including floating or sinking for aquafeed.
- Guaranteed capacity per product family, on a stated recipe and diameter — not an average.
- Grinding fineness required, especially for shrimp and fry feed.
- Durability or water-stability guarantee with a named test method.
- Dryer sizing basis and moisture uniformity commitment (extrusion).
- Steam, power and fuel demand, and energy per tonne at guaranteed capacity, stated by the supplier.
- Wear parts (dies, rollers, screws, inserts, knives) and their expected replacement interval stated by the supplier.
- Scope marked included / excluded / optional, plus installation, commissioning and operator training.
- Incoterms, freight, duties and payment schedule, so you compare landed cost, not ex-works price.
