Feed augers (screw conveyors) are the core of automated feeding systems, moving feed from silos to feeder lines. The three most common diameters for poultry are 45mm, 60mm, and 75mm. Correct selection impacts delivery efficiency and system longevity.

45mm Auger – Small Farms or Main Feed Line
Delivers 250–500 kg/h. Suitable for farms under 5,000 birds, or as a main transfer line from silo to intermediate hopper. Not recommended for full‑house distribution.

60mm Auger – Medium Floor Rearing
Delivers 500–800 kg/h. Ideal for 8,000–15,000 birds. Offers a balance between cost and performance for most commercial floor rearing operations.

75mm Auger – Large Commercial Houses
Delivers 1,000–2,000+ kg/h. Supports 15,000–30,000+ broilers or 120 meters of feeder line for layers. Most economical choice for large farms.

Quick FAQ
Can I use a 60mm auger for a 20,000‑bird house? Not recommended – you would need two 60mm lines or upgrade to 75mm.
Does feed type matter? Yes. Pellets flow easier than mash; for mash, choose one size larger.
