Abstract (en)
[origin: CA3111689A1] The invention relates to a vertical ball mill (100), in particular for the pre-grinding of minerals, comprising: a rotor (204), which is axially and radially supported at an upper end and hangs downward; a stator (102), which radially extends around the rotor (204), is not loaded by the weight of the rotor (204), stands in a self-supporting manner and has a lateral surface that is oriented tangentially to the rotor (204) and that is approximately cylindrical within a shape tolerance; and a base plate (200), which supports the weight of the stator (102), wherein: the stator (102) is composed of at least two stator segments (112), which can be separated from one another, stand unsupported in the separated state and can be moved relative to one another; each of the stator segments (112) has, on at least one side edge of a wall (116) which forms the lateral surface (104), which side edge runs from a top edge of the wall (116) to a bottom edge of the wall (116), a sealing surface for sealing to the other stator segment (112), and has, on the bottom edge, a standing surface (122) dimensioned appropriately for the load, for sealing to the base plate (200); the stator segment (112) rests standing orthogonally on a load-bearing surface (201) of the base plate (200) within an angular tolerance, with the standing surface (122) on the base plate (200).
