The present invention provides a centrifugal projector, said projector being capable of focusing a projection pattern of a projection material and thus being highly efficient in treating a narrow projection area, and a blade that is used for this centrifugal projector. The present invention is a centrifugal projector for projecting a projection material toward an object to be treated, and is equipped with: at least one side plate; multiple blades that are attached to the side plate; a rotary shaft for rotating the side plate and the multiple blades; and an introduction unit for loading a projection material between the multiple blades. Each blade has a projection surface for projecting the projection material, wherein the projection surface has a first section that is formed on the outer side in the radial direction and a second section that is formed on the inner side in the radial direction, the first section is slantingly formed such that the radial-direction outer side is positioned behind the radial-direction inner side in terms of rotating direction, and the second section is formed so as to be positioned ahead of, in terms of the rotating direction, a virtual line that is formed by extending the first section outward in the radial direction. |
