Annular-gap mill

A rotor (1) such that the rotor is of generally cylindrical shape and comprises

• a rotor wall (11),
• a plurality of tools (13) attached to the rotor wall (11),
• a rotor separation ring (12),
• a hub (14), and
• at least one tie-rod (15),
• wherein the rotor wall (11) and the rotor separation ring (12) are clamped onto the hub (14) by the at least one tie-rod (15),
• the rotor separation ring (12) is in the form of a rotationally symmetrical hollow cylinder, and
• the rotor wall (11) is rotationally symmetrical relative to a rotation axis (19) and is mirror-symmetrical relative to a plane of symmetry perpendicular to the rotation axis (19).

A mill for the treatment of flowable materials, wherein the mill comprises the rotor (1) according to claim 15,

• a stator (2) with a stator inside wall (21) and the rotor (1) is arranged inside the stator (2),
• a stator separation ring (22),
• a product inlet (41), and
• a product outlet (42),
• wherein a milling chamber (7) is formed between a stator inside wall (21) and the rotor wall (11) such that the material being milled can pass into the milling chamber (7) through the product inlet (41) and out of the milling chamber (7) through the product outlet (42), and
• wherein, between the rotor separation ring (12) and the stator separation ring (22) there is formed a gap (s) through which the milled flowable material in the milling chamber (7) passes to the product outlet (42).

A rotor (1) having a generally cylindrical shape, the rotor comprising:

• a rotor wall (11),
• a plurality of tools (13) attached to the rotor wall (11),
• a rotor separation ring (12),
• a pair of opposed hubs (14), and
• at least one tie-rod (15) for coupling the pair of opposed hubs (14) to one another,
• wherein the rotor wall (11) and the rotor separation ring (12) are clamped to the pair of hub (14) by the at least one tie-rod (15),
• the rotor separation ring (12) is in the form of a rotationally symmetrical hollow cylinder, and
• the rotor wall (11) is rotationally symmetrical relative to a rotation axis (19) and is mirror-symmetrical relative to a plane of symmetry perpendicular to the rotation axis (19).
