PROBLEM TO BE SOLVED: To provide a method for regenerating slurry capable of improving quality of regenerated slurry and maintaining excellent slice efficiency and precision by suppressing decrease of component effective for the slice efficiency of dispersant, thickener, and the like. SOLUTION: Abrasive grains are separated by a first decanter 31 from used slurry fed to wire rows 11, and secondary separation liquid is separated by a second decanter 32. The secondary separation liquid separated by the second decanter 32 is fed to a mixing tank 30 together with the abrasive grains separated by the first decanter 31 through a pipe line 35, and the regenerated slurry is formed by mixing the abrasive grains separated by the first decanter 31, abrasive grains fed by a hopper 21, and unused fluid dispersion fed from a tank 43. The secondary separation liquid separated by the second decanter 32 is discarded by switching selector valves 33 and 34 provided in the pipe line 35 after a lapse of a specified time, and the unused fluid dispersion of a corresponding amount to the discarded secondary separation liquid is fed from the tank 43 to the mixing tank 30 through pipe line 53 and 35. |
