Abstract

The invention concerns grinding mills of the kind that comprises a circle of grinding rings (1) held between a fixed upper grinding ring (2) and a lower rotatable grinding ring (3a). The lower ring (3a) rests on a support table (4) through a hump (10) projecting from the lower surface of the ring (3a). If the edge of the table should tilt, due to load, say, then the point of contact of the hump (10) and the table (4) will move along the hump (10), so that the moment acting on the ring (3a) will remain approximately constant. The centre of the hump (10) may lie on the vertical passing through the centre of the balls (1) or just radially outwardly of this, to take account of the centrifugal action in operation on the balls. An alternative form of hump is in the form of a flat bottom and two sides that incline gradually away from the plane containing the bottom.
