coal drying processes

Coal Drying Methods. In the past, it has more or less been a general rule that any time the totalproductis being washed, both mechanical and thermaldryingwas required. The reason for this was that a product moisture of 3 to 4% was required andthermal dryingwas and is the only practical method by which this can be accomplished.
