Abstract
The invention relates to an ejector unit, in particular for a road milling machine, having an ejector that is replaceably mounted on a carrier. In one aspect the ejector is curved in a scoop-like fashion. In another aspect the ejector is reversible upon the carrier to allow the ejector to be reversed after one wear surface is worn, thus presenting a new second wear surface.
