Marshal Meru 8 years ago Having used weight control and power draw to control Mill operations, using Mill Sound to run a mill was a new one for me. I found it unusual and not that effective. Has anyone else used that style of operation control to run their mill and did you find it more effective than the more traditional way.

The sound sensor, mounted near the ball mill, gives an AC signal proportional to the Grinding noise which is a function of material bed level in the mill. This signal is routed through a shielded cable, integrated with the sensor unit.
This means the Sensor is only detecting the mill shell vibrations, caused by the Grinding balls hitting the mill lining and material in the mill, and so the Pyrotech Noise Level Sound Transmitter system is insensitive to foreign acoustic noise from other mills or surroundings.
