WebWithin the broad classification of bituminous coal there are several sub-classifications based on volatile content and these are: • Low volatile bituminous coal with < 22% … WebThis International Standard provides description of a cone procedure for determining an uncompacted bulk density of crushed coal less than 37 mm in size, such as is charged into coke ovens. It focuses on the uncompacted bulk density of coal resulting from flowing the material into a measuring container (box) in the absence of compacting forces.
