Description
The MillMinder Audio Signal Convertor listens to the sound levels generated by the impact inside the grinding mill and provides the operator with an output signal which allows automatic material feed control to the mill. A rugged microphone assembly detects this sound at the point of impact of the mill charge. The Microphone/Sound Sensor transmits its signal to an amplifier/convertor where the amplitude at a selected
frequency is amplified and converted to a DC voltage suitable for use by plant operators.
