SLURRY MANAGEMENT DEVICE FOR WIRE SAW

摘要

A wire saw slurry management device is provided with: a first tank (5A) which receives slurry waste (3); a centrifugal separator (14) into which the slurry waste (3b) from the first tank (5A) is introduced and which isolates the slurry (2); a second tank (5B) which receives the solid-content slurry (2) from the centrifugal separator (14); a slurry supply path (26) which supplies the slurry (2) from the second tank (5B) to a fixed-abrasive wire saw (1); a controller (41) which detects the slurry density using a detection value from a density meter (29) and a viscometer (30), both provided on a circulation flow path (28) for extracting and circulating the slurry (2) from the second tank (5B); a slurry discharge path (33) which discharges some of the slurry (2) from the second tank (5B) as waste slurry (31); and a new slurry supply path (38) which supplies new slurry (2a) to the second tank (5B). The discharge of waste slurry (31) by the slurry discharge path (33) and the supply of new slurry (2a) by the new slurry supply path (38) are implemented in order to maintain a specific density for the slurry density detected using the controller (41).
