Agitator ball mill

An agitator mill for processing flowable material to be milled, comprising:

• a circular-cylindrical outer stator,
• an agitator which is rotatably mounted about a common central axis and has a circular-cylindrical rotor, wherein the rotor is arranged within the outer stator, and
• wherein a milling chamber is formed between the rotor and the outer stator, wherein, in the milling chamber, a through-flow direction is defined which extends from a feed channel to a discharge channel,
• wherein the milling chamber between the outer stator and the rotor has a constant width,
• wherein the milling chamber is at least partially filled with milling elements, wherein several rotor milling tools which extend in the direction of the outer stator are attached to the rotor,
• wherein several outer-stator milling tools, which project radially by a length into the milling chamber, are attached to the outer stator, and
• wherein the outer-stator milling tools are arranged adjacent to and at a distance from each other in the circumferential direction and form rows, and
• these rows are arranged parallel to one another on the outer stator along the central axis,
• wherein the outer-stator milling tools comprise a first set of outer-stator milling tools forming a first set of outer-stator milling tool rows and a second set of outer stator milling tools forming a second set of outer-stator milling tool rows, the first set having a greater radial length than the second set, each of the outer-stator milling tools of the first set having the same radial length and each of the outer-stator milling tools of the second set having the same radial length, and
• wherein the outer-stator milling tools of each row have the same length in the circumferential direction.
