  • Patent number: 8038084
    Abstract: The invention relates to a roller mill having a mill housing, a mill path which is supported so as to be rotatable about a mill axis inside the mill housing, and at least one mill roller which can be rotated about a mill roller shaft and which is engaged with the mill path in terms of rolling action. There is further provided a pivot lever which is for rotatably retaining the mill roller and which has a pivot shaft arranged parallel with the mill roller axis and which is supported outside the mill housing. The pivot lever is further in operational contact with a hydropneumatic resilient system in order to adjust the pressing pressure of the mill roller. The pivot lever is supported outside the mill housing with spacing therefrom in such a manner that the forces which are produced by the hydropneumatic resilient system are dissipated into the mill foundation directly or via pillars.
