· The coal samples were used as the feed of the jet milling crushingclassifiion system. The process parameters of the jet milling crushing system were set as follows: the rotation speed of the first classifier was 6000 r·min −1, the rotation speed of the second classifier was 16,000 r·min −1, the pulverization pressure was MPa, and the feed rate was 100 g·min −1 [ 33 ].
one coal type was recommended as the QGESS default for each of the seven coal ranks. 2. Selected default coal specifiions are, as much as possible, representative of the typical coal quality in the United States () commercial market (, as procured by the power plants in the ).
