Cleaning efficiency of the opening roller in a rotor spinning machine, having 56 mm diameter rotor, is 80%. The yarn breaks when the trash deposition within the rotor groove crosses the threshold of 1 mg/mm. If a sliver with 0.4% trash is fed at 7.5 g/min, the number of end breaks in 1 hr (to the nearest whole number) is
