PURPOSE:To eliminate the danger of clogging the narrow circuit of the internal part, etc., of an injection gun and a fluid cyclone by burrs, by providing a burr separating device formed by a rotating frame body spreading a filter passing abrasive grains but no passing burrs of large diameter at the one end upper part of an abrasive grain liquid. CONSTITUTION:An abrasive grain liquid is fed to a burr separation device 3 by the driving of a slurry pump at gun injection rest time. The abrasive grain liquid fed into a filter 18 spread on the inner face of a frame body 14 under rotation of the burr separation device 3 is splashed to the circumference by centrifugal force, the liquid and polishing material are filtered and returned to an abrasive grain liquid tank from a discharging cylinder 8 and the burr in large diameter only is left inside the filter 18. Then, the abrasive grain liquid inside a dirty tank is fed to a polishing material processing device by driving a pump, the refined abrasive grain by the filter action of the filter thereof is sticked to the filter, the liquid only is passed through the filter and fed to a clean tank from the discharging pipe of the tank. |
