An impeller for a centrifugal blast wheel machine includes a hub provided at one end of the impeller, with the hub being configured to be coupled to the motor. The impeller further includes a tapered section provided at an opposite end of the hub, with the tapered section defining a media inlet to receive blast media. The impeller further includes a plurality of drop-shaped vanes positioned between the hub and the tapered section. The plurality of drop-shaped vanes is spaced from one another on peripheries of the hub and the tapered section. The plurality of drop-shaped vanes defines a plurality of impeller media outlets constructed and arranged to allow egress of blast media upon rotation of the impeller. Each vane is drop-shaped having a leading side directed toward a direction of rotation of the impeller and a trailing side opposite the leading side.

Impeller for a blast wheel machine

A centrifugal blast wheel machine comprises a housing and a wheel assembly coupled to the housing. The wheel assembly has a plurality of blades configured to throw blast media introduced into the wheel assembly against a work piece. According to one embodiment, each blade of the plurality of blades includes a curved portion positioned adjacent a central hub of the wheel assembly, and a straight portion integrally formed with the curved portion extending radially outwardly from the wheel assembly. According to another embodiment, each blade includes a first side rail extending along the blade, the first side rail having a first recess, and a first grommet positioned in the first recess.
