The lighter coal moves with the top layer of the wave and discharged at the conical end as low ash coal or clean coal. The high ash coal which settles on the bottom is carried by the spirals to upper cylindrical portion and discharged at the top end as rejects. Thus the rejects and clean coal move in the opposite direction inside the barrel.
