A sorter with a symmetric screen which is arranged concentrically in an essentially symmetric housing, and in the interior of which there is contained a concentric rotor drum that features on its periphery sorting elements sweeping across the screen, circulating at least parts of the suspension being sorted around the walls of the drum. The sorting elements are of a design such that they will generate a vortex flow of the suspension in the housing. The housing features at its periphery at least one removal duct for heavy contaminants and, in one of its end walls, a central lightweight dirt drain. The housing end wall that features the lightweight dirt drain has, in the direction away from the screen and the rotor drum, from radially outside to radially inside, a diameter that tapers in conic fashion by maximally 11 mm per each 3 mm of axial housing length, and minimally by 2 mm per each 3 mm of axial housing length.
