Abstract:
The present invention is a centrifugal projector (1) for projecting projection material (2) toward a processing target, comprising a side plate (11), a plurality of blades (3) attached to the side plate, a rotary shaft (14) for rotating the side plate and the blades, and an introducing part (32) for introducing the projection material between the blades; wherein the blades (3) includes a projection surface (3a) for projecting the projection material, and the projection surface (3a) has a first part (3b) being a radial inner part of the blade and a second part (3c) being a radial outer part of the blade; the first part (3b) is formed to be pitched so that a radial outer side (3e) of the first part is positioned to a rear in the rotational direction (R1) compared to a radial inner side (3f) of the first part, and the second part (3c) of the blade is formed to be positioned to a front in the rotational direction (R1) of an imaginary line (L1) which extends the first part (3b) of the blade toward a radial outer side of the projector.
