Abstract

See full text

A re-circulatory blasting device obtained is capable of performing stable treatment for a prolonged period of time even in cases in which an elastic abrasive employed has abrasive grains adhered to the surface of elastic cores. An elastic abrasive regeneration device provided to the blasting device regenerates elastic abrasive employed for re-circulation. The elastic abrasive regeneration device includes a mixer and a combining unit. Recovered abrasive fed in from an abrasive recovery section is mixed in the mixer with abrasive grains fed in from an abrasive grain feeder, and the abrasive grains are adhered to the surface of the cores of the recovered abrasive. In the combining unit, the abrasive grains are pressed against and combined to the surface of the cores by passing an aggregated state of the recovered abrasive mixed by the mixer along a constricted flow path having a flow path cross-sectional area that gradually narrows.
