[origin: CN110886036A] The invention relates to an opening roller housing for an opening device of an open-end rotor spinning device. The opening roller housing (17) has an inlet opening (27) for feeding fiber strands, an outlet opening (29) for discharging fibers out of the opening roller housing (17), and a dirt separation opening (28) in a peripheral wall (39) of the opening roller housing (17), wherein the opening roller housing (17) comprises a replaceable insert (40). According to the invention, the insert (40) forms a hollow cylindrical ring (41), which has, in the cylinder wall (42), the wall of at least onegroove-shaped fiber inlet (45) having an opening (44) and an inlet/outlet (29) and the wall of an opening (46) used for adjusting the dirt separation opening (28). The insert (40) adjusts the annulargap between the opening roller housings (17) of the opening roller (21) by means of thickness adjustment of the cylinder wall (42) thereof.
