1. A milling drum, comprising:
- a hollow cylindrical supporting barrel extending along an axis of rotation and having an external cylindrical surface;
a plurality of milling devices disposed on said external cylindrical surface, with each milling device comprising a milling chisel and a holder attached to said hollow cylindrical supporting barrel, the holder comprising a base part and a quick-change tool holder, with at least two milling devices of the plurality of milling devices being disposed within any one tool combine disposed in the form of a spiral (W) on said supporting barrel; and
at least one material guiding device designed for guiding milled material under working conditions, the material guiding device comprising a base plate attached directly to said external cylindrical surface, and a guide plate replaceably mounted, directly or indirectly, on the base plate,wherein the material guiding device is disposed within said tool combine between said at least two milling devices pertaining to said spiral (W), as regarded in a direction of rotation (U), andfurther wherein said guide plate of said material guiding device is disposed such that under working conditions said material guiding device at least partially diverts the milled material in the axial direction of the axis of rotation (R).

Abstract
The present invention relates to a milling drum for a ground milling machine, wherein a material guiding device is provided, which diverts the milled material in the direction of stagger of milling devices disposed one behind the other, as regarded in the direction of rotation. For this purpose, in particular, a wear plate is provided, which can be selectively replaced on the material guiding device. A further aspect of the present invention relates to such a material guiding device and also to a wear plate for such a material guiding device.
