Abstract
The invention relates to a roller mill for grinding solid material such as cement raw materials and similar materials, said roller mill comprising a substantially horizontal grinding table and at least two rollers which are configured for interactive operation with said grinding table, wherein at least one of said rollers rotates about a stationary shaft connected to a rocker arm pivotally connected to a mill stand which substantially is situated outside said grinding table and therefore does not utilize a mill stand and the remaining rollers do not utilize a mill stand. According to the invention the number of rollers, and thereby the capacity of the mill is increased without introducing more mill stands.
