Results

Dry Wood

5.5 tons

≈ 10 grand pianos

Pellet Output

4.68 tons

≈ 9 grand pianos

Moisture Removed4.5 tons
Energy Content77.22 MMBtu
How to Use This Calculator
  1. Enter raw wood input in tons and initial moisture content (%).
  2. Set conversion efficiency (%) for your pellet mill.
  3. Review Dry Wood (tons), Pellet Output (tons), Moisture Removed (tons), and Energy Content (MMBtu).
  4. Use these outputs to size drying capacity and plan storage for finished pellets.

How the result changes with Raw Wood (tons)

What each input means

Raw Wood (tons)
Total raw wood feedstock weight in short tons
Moisture Content (%)
Wet-basis moisture percentage of raw wood (green wood is typically 40-55%)
Conversion Efficiency (%)
Fraction of dry wood converted to pellets (accounts for fines, dust, bark loss)

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    Raw Wood (tons) = 10, Moisture Content (%) = 45, Conversion Efficiency (%) = 85 = 3 input(s) provided
  2. Calculate Dry Wood
    Dry Wood
    5.5 = 5.5
  3. Calculate Pellet Output
    Pellet Output
    4.68 = 4.68
  4. Calculate Moisture Removed
    Moisture Removed
    4.5 = 4.5
  5. Calculate Energy Content
    Energy Content
    77.22 = 77.22
