Abstract: An agitator mill having a circular-cylindrical outer stator and an agitator having a circular-cylindrical rotor. The rotor is arranged within the outer stator, and a milling chamber between the rotor and the outer stator. In the milling chamber, a through-flow direction which extends from a feed channel to a discharge channel. Several rotor milling tools are attached to the rotor, wherein several outer-stator milling tools are attached to the outer stator. The outer-stator milling tools are arranged adjacent to and in the circumferential direction and form rows. These rows are arranged parallel to one another on the outer stator. On the side, facing away from the feed channel the outer-stator milling tools of at least one row have a greater radial length than the other outer-stator milling tools. The outer-stator milling tools of each row in the circumferential direction each have the same length.

Abstract: An infeed protection device for a rolling mill, comprising a housing and a plurality of parallel rotating rollers. A product infeed is formed by two of the rollers which rotate about rotational axes arranged parallel with one another and arranged at an adjustable roller space with respect to one another. The infeed protection device comprises a profile which is arranged parallel with the rollers forming the product infeed and extends over the length of the product infeed. In an infeed direction of the rotating rollers, the profile is upstream of the rollers forming the product infeed. At least one vertical through-opening is formed in the profile. A space is formed between the profile and the rollers. The infeed protection device further comprises a holder for fastening the infeed protection device to the housing of the rolling mill.
