PROBLEM TO BE SOLVED: To provide a slurry managing system which can prepare a specific form of slurry, and can prevent the occurrence of an unevenness in the working accuracy of a work, when the slurry is used for a wire saw and the like. SOLUTION: Abrasive grains and a dispersing liquid are fed in a blender tube 54, and they are mixed to prepare a slurry. At the same time, the abrasive grains and the dispersing liquid which can be used yet are separated and recovered from the slurry already used, and they are returned to the blender tube 54 and utilized again. The property of the slurry which consists of the separated and recovered abrasive grains and dispersing liquid is detected by an aerometer 78 and a viscometer 80, and the feeding amount of new abrasive grains and dispersing liquid to the blender tub 54 is regulated and controlled according to the above detecting result. |
