Abstract
A base and ring assembly for a grinding mill includes a base structure with a support plate, an annular support-ring fixedly secured to and positioned above the support plate. The support-ring has a radially inward facing convex surface that extends from a support-ring lower axial end to a support-ring upper axial end. The assembly includes an annular grinding-ring that has a radially outward facing concave surface which extends from a grinding-ring lower axial end to a grinding-ring upper axial end. The grinding ring has a radially inward facing grinding surface. The radially outward facing concave surface is complementary in shape to and engages the radially inward facing convex surface.
