    COARSE DRY COAL CLEANING - Energy

    Potential Dry Cleaning Applications Dry coal cleaning technologies effectively achieve density separations 1.85 RD. Separations at relatively high densities to remove ‘nearly’ pure rock is referred to as deshaling. Dry deshaling technologies are less expensive than wet cleaning processes: – Capital Cost: $6,200/tph versus $13,000/tph
