Abstract: A glass bead separating apparatus and method are disclosed, for use with a slurry blast cabinet. The system is capable of continuous operation, so that glass beads which are broken and undersized can be separated out of the slurry along with debris from the blasting operation, on a continuous basis while blasting takes place, and the slurry can be continuously returned to the blasting cabinet in the purified condition. Used slurry is withdrawn from a hopper at the bottom of the blasting cabinet, pumped up to the top of the separator apparatus and delivered through a nozzle over an inclined screen sized to pass everything but reuseable, whole glass beads. The reuseable beads are collected in a bin, while the remainder passes down onto another, much finer screen which retains nearly everything but the liquid slurry medium, which is preferably water. The relatively clean water drops into a holding tank at the bottom of the separator apparatus, with an overflow weir provided to maintain a preselected water level.
