    The Role Of Drying In Agglomeration Feeco

    Drying plays a critical role in the agglomeration process. When used prior to agglomeration, drying prepares material feedstock for agglomerate formation, and has a direct effect on how material will perform during agglomeration. Used after agglomeration, drying cures pellets into their final, strong form.
