Pig Feed Pellet Machine Small Scale: Complete Selection Guide
News 2026-07-30
Page SEO Summary: This technical guide helps small farmers and entrepreneurs evaluate small scale pig feed pellet machines—covering equipment types, capacity selection, investment considerations, and profitability analysis.
The global pork industry is dominated by large commercial operations, but small-scale pig farming remains vital in many regions. For small farmers, feed costs represent the largest operating expense. Producing feed on-farm can significantly reduce costs and improve profitability—even on a small scale.
A small scale pig feed pellet machine makes feed production accessible to farmers with 50-500 pigs. These machines are designed to be affordable, simple to operate, and capable of producing high-quality pellets from locally available ingredients.
This guide provides a comprehensive framework for understanding, selecting, and procuring small scale pig feed pellet machines.

Frequently Asked Questions
1. What is a small scale pig feed pellet machine?
A small scale pig feed pellet machine is a compact, affordable machine designed to produce feed pellets for small to medium pig operations. It typically uses a flat die or small ring die and is designed for simple operation and low maintenance.
2. What capacity do I need for my pigs?
A 100-pig operation needs approximately 50-100 kg/h of feed production. Use the formula: (pigs × daily feed per pig) ÷ (operating hours).
3. What is the difference between flat die and ring die?
Flat die is simpler, lower cost, and suitable for 20-150 kg/h. Ring die is more efficient, higher output, and suitable for 150-500+ kg/h. Ring die produces better quality pellets.
4. How much does a small pig feed pellet mill cost?
Flat die machines cost $300-2,000. Ring die machines cost $2,000-8,000. Complete lines cost $2,300-15,000.
5. Is it profitable to make pig feed on a small scale?
Yes. On-farm feed production can save 10-20% compared to purchased feed. For a 100-pig operation, savings of $2,000-4,000 per year are typical, with payback in 1-2 years.
6. What pellet size is best for pigs?
Weaners: 2.0-2.5 mm; growers: 2.5-3.5 mm; finishers: 3.5-4.5 mm; sows: 4.0-5.0 mm. Different sizes for different stages.
7. Do I need 3-phase power?
Flat die machines can run on single-phase (220V) for small capacities. Ring die machines require 3-phase power (380V) for larger capacities. Check your power supply before selecting equipment.
8. What are the main feed ingredients?
Corn (energy), soybean meal (protein), wheat bran (fiber), and mineral/vitamin premix. Local ingredients can substitute based on availability and cost.
