Abstract
PURPOSE: To prevent sedimentation of a pulverized coal in a coal slurry composed of pulverized coal and an oil, in a storage tank, by restricting the content of large- size particles within a specified limit.
CONSTITUTION: A material is supplied to screw feeder 9 through coal feeder 2, raw crusher 4, etc., and introduced together with an oil from oil tank 11 with agitation, to wet mill 10, where it is pulverized and mixed, forming coal slurry, and the slurry is discharged to collect tank 18. The slurry in the tank 18 is sampled from time to time and distribution of the particle size of the pulverized coal in the slurry is determined. when the pulverized coal contains 1.5wt% or less particle having particle size ≥300μ, the slurry is carried to storage tank 23, and when 1.5wt% or more, the slurry is returned through return conduit 29, etc. to the wet mill 10, where it is pulverized again.
