A rock crusher (10) including a turntable (26) with a series of impellers (34) mounted thereon. Each impeller (34) includes a curved, C-shaped pocket (56) that includes a radially inwardly sloped wall (59) terminating in a transversely extending lip (111). The impeller (34) is oriented in a somewhat closed position or greater angle of attack (90) so that the front face (54) of the impeller is exposed to oncoming rocks. A method of retaining rock fines (116) in a pocketed impeller (34) of a rock crusher (10) which includes orienting a radially outermost pocket wall (59) in a radially inwardly sloped orientation is disclosed.
