ABSTRACT:
A crusher roller having a pair of roll hubs mounted on a shaft. Each hub has an external taper on its radially outer surface and an annular recess in each end adjacent to the inner surface. A shrink disc with an internal taper on the inner surface is positioned within each annular recess adjacent to the inner surface of the roll hubs. A circular wedge having an external taper on its outer surface is positioned between each shrink disc and the inner surface of each annular recess and bolts connecting the shrink discs in each roll hub for drawing the shrink discs together to secure each roll hub to the shaft. An expansion ring is mounted radially outward of the roll hubs and a roll shell is mounted on the outer surface of the expansion ring. A roll wedge with an internal taper on the inner surface is mounted between each roll hub and the inner surface of the expansion ring and roll wedge bolts draw the roll wedges together to apply a radially outward force to the expansion ring to hold the roll shell in place on the expansion ring.
