Abstract
The present invention provides a blasting device, comprising: a container in which a blast medium is stored; a suction pipe which is inserted in the container to be rotatably supported, and is formed substantially in an L-shape with a lower suction port bent at a right angle; a rotary drive part which rotates the suction pipe; a hose connected to the suction pipe via a rotary joint; an ejector nozzle connected to the hose; an air compressor which supplies compressed air to the ejector nozzle; a pressure sensor which measures pressure in the suction pipe; and a control part which controls a rotational frequency of the suction pipe by the rotary drive mechanism based on a measured value by the pressure sensor.
