Abstract

A segmented grinding ring device for use with a tub mill spray tub and comprising a plurality of truncated wedge-shaped members which, when held together in side-to-side relationship, form a ring, each having truncated wedge-shaped member two flat side surfaces adapted to be in contact with the flat side surfaces of the following adjacent members, characterized in that each segment is a one-piece cast machined construction, because each segment has a inner peripheral surface and an outer peripheral surface and because a groove is formed in both peripheral surfaces that extends from one lateral surface to the other to receive retaining means by means of which the segments are attached to the tub.
