Abstract
To obtain a circulation-type blasting device which enables stable processing for a long period of time even in a case that an elastic abrasive of which abrasive grains are attached to a surface of an elastic core are used. A circulation-type blasting device is provided with a device for recycling an elastic abrasive for recycling all or a part of elastic abrasive used in a cyclic way, and the device for recycling the elastic abrasive is provided with a mixing unit for mixing recovered abrasives recovered from an abrasive recovery unit and abrasive grains introduced from an abrasive grain supplying unit in a gas flow by introducing the abrasive grains and the recovered abrasive in the gas flow to generate a solid-gas biphase flow, and a combining unit composed of at least one bent space to which the solid-gas biphase flow is introduced.
