    the finer sized coal, smaller than about 6 mm, is not effectively upgraded in the FGX. It proves more productive to dryscreen the feed at 6 mm and only feed the plus 6 mm coal to the FGX unit. This results in the added benefit of increasing the capacity of the plant since only the plus 6 mm size fraction needs to be processed via the FGX. Removal of the fine coal from the FGX feed also ...
