A rotor spinning apparatus includes a support frame stationarily disposed on a frame of a spinning machine. A bearing is disposed on the support frame. A spinning rotor is disposed on the bearing and has a rotor axis and a rotor opening. A rotor housing surrounds the spinning rotor. A lid element is rotatably supported about a pivot axis. The pivot axis is oriented orthogonally to the rotor axis and is disposed approximately vertically beneath the rotor opening. The lid element covers the rotor housing and has a sliver feed roller, an opening roller, a fiber guide channel plunging into the rotor opening, a yarn draw-off opening, and a dirt separator.
