Abstract: An object is to adjust a lower limit of a shot amount with high accuracy. A processor of a shot-blasting device adjusts a degree of opening of a gate of a distributor, which supplies a blasting medium, by subjecting a cylinder in a state of opening the gate to position control with use of a servo motor, so that a load current value of a motor of an impeller falls within a set range having a current lower limit.

Abstract: A classification device includes: a sorting mechanism that sorts a group of powder particles using an airflow; a dust collector that generates the airflow; a measuring instrument that measures a measurement value related to a speed of the airflow; and a control device that performs wind speed control that controls the speed of the airflow so that the measurement value is maintained within a control range.

Abstract: A processor (213) carries out, after a device is activated and before a blasting medium projected to a projection target object (500), a first inspection process (T1) for determining, in a state in which no blasting medium (400) is supplied to an impeller (110) while each motor of the impeller is rotating, whether a current value supplied to the each motor of the impeller is not more than a first threshold (θ1), and a second inspection process (T′1) for determining, in a state in which the impeller is projecting the blasting medium, whether the current value supplied to the each motor of the impeller is not less than a second threshold (θ2), and displays, on a display (300), at least one of (1) respective determination results of the first inspection process and the second inspection process and (2) a determination result obtained by generalizing the determination results (1).
