# horse power calculations to rotate a ball mill

• ### Required torque to rotate a solid cylinder around its axis

· What I want to know is how to calculate the torque required to maintain the cylinder rotating at the desired speed once it reaches it. From what I understood it is dependent on the friction at the bearings only. The formula I have found is T=μ m g R where T the required torque. μ the friction coefficient. m the weight of the cylinder.
