Vertical roller mill

A vertical roller mill having a mill foundation comprising a grinding table adapted for rotation about a vertical axis, at least two grinding rollers positioned in engagement with said grinding table, at least two stationary generally horizontally mounted roller shafts each having an inner end portion positioned adjacent the vertical axis and an outer end portion, each grinding roller being adapted for rotation on a respective shaft, means anchored in the mill foundation for pressing the grinding rollers against the grinding table, a frame positioned centrally of the grinding table, said roller shafts being secured to said frame at their inner end portions and said pressing means being pivotally coupled to the outer end portions of the roller shafts.

Vertical roller mill having a mill foundation, a grinding table which rotates around a vertical axis and at least two grinding rollers rotating around stationary generally horizontally mounted shafts each having an inner end facing the mill axis and an outer end, the rollers being urged against the grinding table by means of draw bars anchored in the mill foundation, characterized in that all the roller shafts at their inner ends are secured to a common frame centrally positioned in relation to said grinding table, the draw bars being pivotally connected to the outer ends of said respective shafts.

A vertical roller mill comprising a horizontal grinding table adapted for rotation about a central vertical axis, at least two upright grinding rollers positioned with their peripheral grinding surfaces in engagement with said grinding table for grinding material thereon, each grinding roller being positioned for rotation on a respective horizontal roller shaft having an inner end and an outer end, a draw bar associated with each roller shaft, each draw bar being anchored at one end to the mill foundation and being pivotably connected at the other end to the outer end of the respective roller shaft, each draw bar having means for urging the respective rollers against said horizontal grinding table, a frame centrally positioned in relation to said grinding table, said frame being connected to the inner ends of said associated roller shafts.
