Abstract
With the blasting apparatus in which the injection nozzle is disposed to inject the blast material against the work pieces from the outside of the tubular barrel formed of the mesh net for accommodation of the work pieces and rotatable about the center axis, the work pieces can be stirred homogenously and efficiently without excessive occurrence of the collision of the work pieces against one another and without occurrence of the collision of the work pieces against one another and with a strong shock force. Therefore, the treating efficiency is enhanced and, it is possible to inhibit the occurrence of the cracking and breaking of the work pieces. Further, with the blasting apparatus in which the tubular barrel is supported circumferentially outside the center axis of the support member rotatable about the center axis, it is possible to more inhibit the occurrence of the cracking and breaking of the work pieces.
