BLAST PROCESSING DEVICE AND BLAST PROCESSING METHOD

摘要

To provide a blast processing device capable of jetting the fixed amount of abrasive material.SOLUTION: A blast processing device includes: a nozzle that jets abrasive material with compressed air; a storage portion that stores the abrasive material inside; a roller that has a cylindrical shape, is provided with a groove-shaped recessed portion on a circumferential surface, and has a rotary shaft extending in a center axis direction; a driving portion that rotates the roller about the rotary shaft; a filling portion that is disposed adjacent to the roller, and fills the abrasive material stored in the storage portion to the opposite recessed portion; a taking-out portion that is disposed adjacent to the roller on the downstream side in a rotating direction of the roller than the filling portion, and takes out the abrasive material from the opposite recessed portion by using an air flow generated in a direction parallel with an extending direction of the recessed portion; and a supply pipe that supplies the abrasive material taken out from the taking-out portion.SELECTED DRAWING: Figure 1
