torque speed calculation for ball mill

7 Starting and running torques
torque of high speed ball bearings is shown in Fig 1 A comparison of values calculated using these equations and actual measurements is shown in Fig 2 When the contact angle exceeds 30 the influence of spin friction becomes big so the running torque given by the equations will be low Calculation Example Obtain the running torque of
