摘要

PURPOSE:To continuously and stably produce the subject coal-water slurry having high quality by adding a dispersing agent to a specific powdered coal, stirring the mixture and crushing the fluidized mixture with a crusher. CONSTITUTION:Powdered coal (coal dressing sludge S) having high water content and high ash content and discharged from a coal dressing factory is charged together with a dispersing agent D into a mixer 1 and fluidized by stirring and mixing for a prescribed period. The fluidized coal powder is supplied through a slurry feed tank 3 to a crusher 6 and crushed to obtain the objective high-concentration coal-water slurry.
