Bearing arrangement of a horizontal grinding mill and method for determining the fill rate of the mill

A bearing arrangement for a horizontal grinding mill, the grinding mill including a drum, the bearing arrangement comprising:

• a first bearing device and a second bearing device, the drum being rotationally supported by the first and second bearing devices;
• load determining means configured to determine a load applied on the first bearing device;
• and
• fill rate determining means configured to determine a fill rate of the drum during operation of the horizontal grinding mill from a first relationship determined during a calibration period, the first relationship correlating the fill rate of the drum to the determined load applied on the first bearing device.
