Claim:
Roller mill having a mill housing ( 1 ), a mill path which is supported so as to be rotatable about a mill axis ( 2 ) inside the mill housing, at least one mill roller ( 4 ) which can be rotated about a mill roller axis ( 5 ) and which is engaged with the mill path in terms of rolling action, at least one pivot lever ( 6 ) which is for rotatably retaining the mill roller ( 4 ) and which has a pivot shaft ( 7 ) arranged parallel with the mill roller axis ( 5 ) and which is supported outside the mill housing, and having at least one pressing system which is in operational contact with the pivot lever in order to adjust the pressing pressure of the mill roller ( 4 ), wherein the pressing system is formed by a hydropneumatic resilient system ( 8 ) and the pivot lever ( 6 ) is supported with spacing from the mill housing ( 1 ) in such a manner that the forces which are produced by the pressing system are dissipated into a mill foundation directly or via pillars, wherein the bearing of the pivot lever ( 6 ) has a first bearing ( 12 a ) and a second spaced-apart bearing ( 12 b ) having a common pivot axis ( 7 ) and the ratio of the distance (L 2 ) between the mill roller ( 4 ) and the first bearing ( 12 a ) relative to the distance (L 1 ) between the two bearings ( 12 a , 12 b ) is from 1:0.5 to 1:2.
