the role of microorganisms in coal mining crusher

Coal Slurry

Coal slurry is first prepared by crushing the coal to a size of 0.2 mm particle diameter along with water addition. The coal slurry is the pumped to the gasifier where the reactions take place in the controlled amount of oxygen. The gasifier effluent contains a mixture of gaseous products including CO, H 2, CO 2, H 2 O, Ar, H 2 S and minor quantities of other gases.
