摘要： A stirred ball mill may include a milling jar, at least three agitator shafts, and a drive. The milling jar may be arranged in a main direction and may have a milling chamber that is adapted to receive milling material and milling aid elements. Each of the at least three agitator shafts has a center axis that is arranged parallel to the main direction of the milling jar and is configured as a screw that is mounted fixedly to a frame in the milling jar such that each agitator shaft is rotatable about its center axis. The drive is configured to rotate the agitator shafts about their respective center axes without any contact between the agitator shafts. The center axes of the agitator shafts may be arranged as side edges of a prism.
