  • Recycling system of wire saw abrasive grain slurry and centrifugal separators therefor
    Patent number: 6615817
    Abstract: A constitution comprises separated processing of an abrasive grain waste liquid into recycled abrasive grain and a fine abrasive grain mixed liquid in a first centrifugal separator, adding a fresh cutting liquid to the fine abrasive grain mixed liquid to direct the resulting liquid to a second centrifugal separator to subject the same to separated processing in the second centrifugal separator, into waste abrasive grain and a recovered cutting liquid directing the recovered cutting liquid through a recovered cutting liquid tank to a recovered abrasive grain tank, adding fresh abrasive grain and a cutting liquid for dilution to the recovered cutting liquid in the recovered cutting liquid tank and to the recycled abrasive grain to create a recycled abrasive grain mixed cutting liquid, and feeding the recycled abrasive grain mixed cutting liquid to an abrasive grain supply tank.
