Since the impeller-type projector 2 is larger than the nozzle-type projector that sprays the shot with the nozzle force together with the compressed air, mounting it on the side wall instead of the top surface of the cabinet 1 reduces the height of the shot blasting device. It is effective in doing.

- the second motor 70 operates, and the rotation plate 69 on the projection chamber 66 side rotates, and the work W rotates in the projection chamber 66.
- the opening / closing gate 76 is opened, and the spinning work W heshing in the projection chamber 66 is projected by the operation of the centrifugal projector 73.
- the projection of a shot onto one work W is continued for a desired time.
- the shots dropped from the projection chamber 66 are collected by the screw conveyor 71 and transferred to the packet elevator 72.
- the shot conveyed upward by the packet elevator 72 is put into a shot 75 and circulated.
- the transport amount of the packet elevator 72 is set to be larger than the total projection amount of the centrifugal projector 73. Therefore, a part of the shot put into the chute 75 overflows from the opening / closing gate 76 when the opening / closing gate 76 is opened and supplied to the projector 73.
- the overflowed shot is supplied to the separator 78.
- the opening / closing gate 76 is closed! /, So during this period it is transported upward by the packet elevator 72 and shut down.
- the entire amount of the shot input to 75 is supplied to the separator 78.
- the shot supplied to the separator 78 falls in the direction shown by the arrow in FIG. 12, and is collected by the screw conveyor 71. At this time, the dust inside the separator 78 is collected through the suction port 82. Suctioned by the machine 74. For this reason, the impurities are sucked into the dust collector 74 by the airflow and separated from the shot. The sucked impurities flow into the sedimentation chamber 81, of which the light one (for example, fine powder) is sucked by the suction duct 80, and the heavy one (for example, reusable shot) is the screw conveyor 71. Is returned to.
- the opening / closing gate 76 closes and the second motor 70 stops.
- the first motor 65 is operated, and the revolution plate 62 rotates 180 degrees about the revolution shaft 64.
- the workpiece W subjected to the projection processing moves from the projection chamber 66 into the loading / unloading chamber 67, and the workpiece W to be subjected to the projection processing next moves from the loading / unloading chamber 67 into the projection chamber 66.
- the work W to be subjected to the projection processing which has been moved into the projection chamber 66, is subjected to the projection processing while rotating, similarly to the processing for the previous work W described above.
- the workpiece W in the loading / unloading chamber 67 which has been subjected to the projection processing, is unloaded from the loading / unloading chamber 67, and the empty hanger 68 in the loading / unloading chamber 67 is further subjected to the workpiece W to be subjected to the projection processing. Is suspended.
- the suction operation is performed by the operation of the above-described blower 79, and impurities such as fine powder are sucked from the suction duct 80 and the first branch duct 80a.
- the gas containing impurities flows in the direction shown by the arrow in FIG. 13 and flows into the dust collector 74.
- the gas that has flowed into the dust collector 74 flows from outside the plurality of flat plate type cartridge filters 85 into the inside.
