METHOD AND DEVICE FOR MANUFACTURING ELASTIC ABRASIVE METHOD FOR BLASTING THE ELASTIC ABRASIVE INCLUDING METHOD FOR RECYCLING THE ELASTIC ABRASIVE AND DEVICE FOR BLASTING THE ELASTIC ABRASIVE INCLUDING DEVICE FOR RECYCLING THE ELASTIC ABRASIVE

摘要

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.

1. A method for manufacturing an elastic abrasive composed of a core made of an elastic material and having adhesiveness at least on a surface of the core and abrasive grains attached to the surface of the core, comprising:
a mixing step for mixing the abrasive grains and the core in a gas flow by introducing the abrasive grains and the core together in the gas flow to generate a solid-gas biphase flow; and a combining step for combining the abrasive grains with the surface of the core by introducing the solid-gas biphase flow generated in the mixing step in at least one bent space then passing through the bent space by propulsive force and/or centrifugal force of the solid-gas biphase flow thereby pressing the abrasive grains to the surface of the core.
