Abstract: A straight-drum centrifugal dehydration device, wherein extraction of moisture from heavy phase built up in a bowl is facilitated to improve the dehydration effect, and compression efficiency is improved to achieve a reduced load. The straight-drum centrifugal dehydration device, wherein an outer peripheral surface of a rotary drum (21) of a screw conveyor (20) comprises a straight section (24) and a tapered section (25) that spreads outward and away from the straight section, the straight-drum centrifugal dehydration device having an inorganic flocculant feed path for feeding an inorganic flocculant to an inner peripheral surface of the straight section (24) of the rotary drum, and the straight section being provided with an inorganic flocculant addition nozzle (109) communicating with the inorganic flocculant feed path and projecting into an annular space of the bowl and an orifice (108) for adding the inorganic flocculant.

Abstract: In a wet agitating ball mill, a shaft 5 rotated and driven by a motor is hollow at its axial center at an upper portion, a discharge route 9 communicating with a slurry discharge port is provided, and a rotor 11 is affixed at the lower portion of the shaft. A separator 4 is composed of a pair of disks 21 and a blade 22 for coupling both disks to form an impeller, and by its rotation, a centrifugal force is applied to the slurry and media getting in the separator 4, and by the difference in specific gravity of the two, accordingly, the media having the heavier specific gravity is expelled and separated in the radial direction, while the slurry of the lighter specific gravity is discharged through the discharge route 9 of the shaft 5 in a state free from kinetic energy.
