    TECHNICAL DESCRIPTION OF THE WOOD PELLETING PROCESS

    With this technical report we want to describe the different stages of the wood pellets production process.

    DESCRIPTION OF THE PROCESS STAGES

    The production process can vary significantly depending on the starting material (logs, chips, sawdust,…), moisture (dry, wet) and depending on the type of initial storage and/or the lay-out required.

    In general, the sections into which the pelleting plant can be divided are as follows:

    1. Chipping and/or primary grinding
    2. Selection and preparation of the material
    3. Secondary grinding
    4. Drying
    5. Refining
    6. Pressing
    7. Cooling and sieving
    8. Packaging and palletising
