Abstract
An improved vane for use with a centrifugal throwing apparatus. The vane has a convex leading surface and flared edges to provide a consistent, broad blast pattern and improved vane wear characteristics. In one embodiment, the vane includes a pickup end, a discharge end opposed to the pickup end, and a leading surface connecting the pickup end to the discharge end. A portion of the leading surface is convex in cross section. Two opposed longitudinal edges define the leading surface, with at least one of the edges being outwardly flared. In an alternative embodiment, the vane includes a longitudinal raised rail formed near one edge of the leading surface, the rail being outwardly flared.
