<p>The present invention provides a blasting apparatus (20) (70) which is provided with an ejection device, which ejects blast media (26), and a recovery device (54), which sucks and recovers ejected and used blast media (26), on a traveling carriage (74) (76), ejects the blast media (26) to a surface to be treated by the ejection device while causing the traveling carriage (74) (76) to travel on the surface to be treated, and recovers the used blast media (26) by the recovery device (54), further comprising a roughness measuring device (84) that is provided at the traveling carriage (74) (76) and measures roughness of an uneven surface of the surface to be treated which is treated by ejection of the blast media (26); and a control unit (82) which performs a feedback control of an ejection amount of the blast media (26), ejection pressure, ejection speed, an ejection air amount, a suction air amount by the recovery device (54), and a speed of the traveling carriage (74) (76) so that the roughness which is measured by the roughness measuring device (84) is within a range of predetermined roughness.</p> |
