description	The purpose of the invention to provide a method for determining a lifting angle of a charge inside a grinding mill at a specific point in time and a method for positioning a grinding mill which is more accurate. Method for determining a lifting angle of a charge inside a mill body of a grinding mill being rotatable through a drive train, the method comprises the following steps of rotating the mill body; determining a reference lifting angle and a corresponding reference driving torque of the drive train at a reference point in time; calculating a fill factor for the reference point in time based on the reference lifting angle and the reference driving torque; determining a driving torque of the drive train; and calculating the lifting angle based on the driving torque and the fill factor.
