RECOVERY AND REUSE OF ABRASIVE AND VEHICLE FROM WIRE SAW SPENT SLURRY

摘要

A simple, elegant, economical method for the recovery of abrasive and vehicle from the used slurry of w saw. The important feature of the method is to dilute the highly viscous used slurry with the same vehi from which the slurry was originally prepared to bring down the viscosity to the desired value. Separati this slurry into thick sludge and thin slurry. The thick sludge is dispersed in the same vehicle and made with fresh abrasive to prepare a slurry suitable for use in the wire saw. The thin slurry is subjected separation of the solid as a thick cake and a clear vehicle, which is reused for preparing the slurry aga Extracting the remaining vehicle from the thick cake using suitable procedures and discarding the soli containing the kerfs and other impurities with some small quantity of abrasive and vehicle as a waste.
