To solve the problem that the quality control of recycled abrasive grain slurry, a decrease in used amount of expensive abrasive grain slurry and the effective use of resources are not achieved because there is no system for recycling and managing wire saw abrasive grain slurry, in which an abrasive grain waste liquid or fine abrasive grain mixed liquid amount to be supplied to first and second centrifugal separation chambers and a new abrasive grain or new cutting liquid amount are managed, a required new abrasive grain and/or new cutting liquid amount is managed and such management is processed by network.

This system for recycling the wire saw abrasive grain slurry comprises inputting into a computer the abrasive grain waste liquid or fine abrasive grain mixed liquid amount to be supplied to the first and second centrifugal separation chambers and the new abrasive grain or new cutting liquid amount to be supplied to a collected abrasive grain tank and an abrasive grain supply tank and individually processing an abrasive grain waste liquid or fine abrasive grain mixed liquid set amount and a new abrasive grain or new cutting liquid set amount for managing whether processed values are within allowable ranges or not, identifying the management status on the network, managing the abrasive grain waste liquid or fine abrasive grain mixed liquid amount and the new abrasive grain or new cutting liquid amount and maintaining the quality of the recycled abrasive grain slurry. With the management of the abrasive grain waste liquid or fine abrasive grain mixed liquid amount and the new abrasive grain or new cutting liquid amount and the network processing of the management, the abrasive grain waste liquid or fine abrasive grain mixed liquid amount is automatically managed.
