Abstract
The invention relates to a roller mill, particularly an air-swept roller mill provided with a device for separating magnetizable constituents, particularly iron particles from the milling area. The invention also relates to a method for grinding materials with magnetizable, particularly iron-containing constituents, e.g. slag, in an air-swept roller mill where, for avoiding concentrations of magnetizable particles, particularly iron particles, on the grinding pan, said particles are electromagnetically separated and removed from the roller mill.

1-20. (canceled)
A roller mill operating on a grinding material containing magnetizable constituents, the roller mill comprising:
- a mill casing defining a milling area;
- a grinding pan having a grinding path;
- at least one grinding roller in the mill casing for rolling on the grinding material on the grinding path of the grinding pan;
- an electromagnetic device having a roller-like construction rolling on the grinding material for separating the magnetizable constituents from the grinding material;
- and
- a discharge mechanism connected to the electromagnetic device for removing the separated, magnetizable constituents from the milling area.
The roller mill according to claim 7, wherein the stripper and the conveyor trough are fixed to the roller axis or to the rocking lever of the slave roller.
