Classification Of Coal Mills - mapymysli.edu.pl
Coal classification, any of various ways in which coal is grouped. Most classifications are based on the results of chemical analyses and physical tests, but some are more empirical in nature. Coal classifications are important because they provide valuable information to commercial users (e.g., for power generation and coke manufacturing) and to researchers studying the origin of coal.
