Abstract
A die segment for a briquetting roll in which the roll is a steel body which is provided with a peripheral groove having a radially outwardly facing bottom wall which is made up of planar chordal segments and having side walls at the side edges of the bottom wall with one side wall inclined inwardly in the outward direction and being in the form of an annular segment of a cone concentric with the axis of the roll and the other side wall substantially radial. The die segments are bodies of hard wear resistant material mounted in the groove, one on each chordal section of the bottom wall of the groove and each has one side inclined to fit the inclined wall of the groove with the other side spaced from and diverging from the radial side wall in the outward direction. Wedge bars between the radial side wall of the groove and the opposed sides of the die segments are utilized for clamping the segments in place in the roll.
