ABSTRACT:
A ball or grindstone crusher comprises a frame including a support and a table mounted on the frame support for rotation about a vertical axis, and table having arranged thereon an annular track and the frame support extending in a plane below the annular track. Balls or grindstones are rollingly supported on the track and are pressed thereagainst. A first series of bearings supports the table on the frame support and a second series of bearings is disposed at the same level as the first series of bearings. The table has a skirt defining a cylindrical surface coaxial with the annular track and the second series of bearings bears against the cylindrical surface and thereby maintains the table in a stable lateral position with respect to the axis of rotation.
