  • Patent number: 11944976
    Abstract: A vertical ball mill includes: a rotor, which is axially and radially supported at an upper end; a stator, which radially extends around the rotor, stands in a self-supporting manner and has a lateral surface that is oriented tangentially to the rotor; and a base plate supporting the weight of the stator. The stator includes least two stator segments, which may be separated from one another, stand unsupported in the separated state and may be moved relative to one another; wherein each of the stator segments has, on at least one side edge of a wall which forms the lateral surface, a sealing surface for sealing to the other stator segment, and has, on the bottom edge, a standing surface for sealing to the base plate; wherein the stator segment standing surface weighs on a load-bearing surface of the base plate.
