Choosing the right pellet mill size depends on the type of production—animal feed or biomass pellets—and the daily production requirements. Here’s a clear guide to help you determine the best fit:

1. Animal Feed Pellet Mill
   • Minimum Output: 1 ton per hour
   • Daily Production Example:
   • If you produce chicken feed and operate 8 hours a day, the smallest pellet mill will produce 8 tons per day.
   • A chicken consumes approximately 100-120g of feed per day, meaning the output can feed around 80,000 chickens per day.
   • This demonstrates that even the smallest commercial animal feed pellet mill can handle substantial production, making it ideal for medium to large-scale poultry or livestock farms.
2. Biomass Pellet Mill
   • Minimum Output: 500 kilograms per hour
   • Daily Production Example:
   • If you produce wood pellets and operate 8 hours a day, the smallest biomass pellet mill will produce 4 tons of pellets per day.
   • Considering the drying process, 5 tons of woodchip raw material is typically needed to produce these 4 tons of pellets, as drying can result in a reduction in weight depending on the moisture content of the raw material.
   • This emphasizes that selecting the correct biomass pellet mill size requires careful consideration of raw material availability and drying efficiency.
3. Guiding Principle
   • Determine Production Needs: Calculate your daily production requirements based on the number of animals (for feed) or raw material availability (for biomass).
