    The mass ratio of air to coal is dependent on the coal mill manufacturer and usually ranges from 1.75 to 2.2 with a typical value of 2.0. An air to fuel mass ratio of 1.8 produces a primary stoichiometric ratio of approximately 0.16, or 16% of the air necessary for complete combustion of the coal.

    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.
