Before coking, pyrolysis or gasification of coal , feed coal need be retreated, such as coal graded crushing, moisture control and so on. In this paper, the coal graded crushing and moisture control technology was analyzed and studied, and characteristics and development tread of the technology were discussed. The results show that, the coal graded crushing and moisture control technology is the development trend of coal pretreatment technology, especially the technology of fluidization- entrained flow bed, which should be emphatically developed.
