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.

  • Coal Beneficiation Technology 2007 Initiatives, Policies

    Coal Beneficiation Coal beneficiation is a process by which the quality of raw coal is improved by either reducing the extraneous matter that gets extracted along with the mined coal or reducing the associated ash or both. Two basic processes of beneficiation: Dry-deshaling: Non-coal or shaly-coal is removed without using any liquid media.
