# vibration signal for measuring ball mill load

### The automatic control system (ACS) of the ball mill s load.

The ACS can control the load of the mill by the specific algorithm that takes into account the interrelated parameters such as calculating the volume of the coal loading in the mill and the temperature of dust-air mixture at the output from the mill. Measuring of the volume of load of the mill s drum is made with the help of vibration
