PROBLEM TO BE SOLVED: To suppress entrainment of air into a slurry discharged from a slurry mixing tank, and stabilize a performance of a liquid pump.CONSTITUTION: A dihydrate gypsum aqueous slurry is supplied from a supply port, along an inner peripheral direction of a cylindrical mixing tank, thereby a slurry revolving stream is formed in the mixing tank, and gypsum hemihydrate powder is put from an upper part of the mixing tank. Then, the slurry is discharged from a discharge port on a position of the mixing tank, except for a side face, or a central part of a bottom face of the mixing tank, toward a same direction of the revolving stream.SELECTED DRAWING: Figure 1 |
