The modern-day coal processing plants can be categorized into four different circuits, depending upon the size of the coal particles to be treated: (a) coarse coal processing circuit treating particles coarser than 10 mm, (b) small coal circuit for washing particles in the size range of 1-10 mm, (c) fine coal circuit for cleaning particles in ...
FGX operates well on coal with a top size of about 50 mm. It was found in tests conducted on the FGX that the finer sized coal, smaller than about 6 mm, is not effectively upgraded in the FGX. It proves more productive to dry-screen the feed at 6 mm and only feed the plus 6 mm coal to the FGX unit. This results
