Claims

[Claims for Utility Model Registration] (1) A tube mill to which raw coal or raw coal, water, a surfactant, and an alkaline substance are supplied, and a classification for removing coarse particles contained in the coal-water slurry overflowing from the tube mill. In the coal-water slurry manufacturing apparatus, the inside of the tube mill is divided into two or more chambers by perforated plates, and a coarse pulverizer for coarsely pulverizing the raw material coal is provided,
An ultra-fine pulverizer is provided for pulverizing the pulverized coal of the coarse pulverizer into a finer particle than the tube mill, and the coal-water slurry obtained by the ultra-fine pulverizer is supplied to a chamber on the coal-water slurry outlet side of the tube mill. Highly concentrated coal-water slurry production equipment featuring a line. (2) The ultrafine pulverizer comprises a cylindrical container provided with stirring blades inside, and the container is filled with balls, as set forth in claim 1 of the utility model registration claim. Highly concentrated coal-water slurry production equipment.
