Abstract

A separator arrangement has an inlet head housing, a feed drum and two axial separating rotors projecting by one end portionwise into the inlet head housing. The inlet head housing has planar inlet portions which extend over the width of the respective axial separating rotor and between which is arranged a ramp-shaped housing portion extending paraxial to the conveying direction of the axial separating rotors and which assists in dividing a harvested material flow into partial flows to be fed to the axial separating rotors. At least one separating element is associated with the ramp-shaped housing portion and has a base body which extends perpendicular to the surface of the housing portion and which has an end face formed as a cutting edge. A coating comprising a wear-resistant second material is arranged on the end face and extends substantially medially in the longitudinal direction of the end face.
