Mill level monitoring

February 2012 Level Measurement & Control

Simple and efficient, the audio signal convertor known as Millminder is a well engineered automatic feed control system for grinding mills. The system uses a specialised microphone to monitor the sound generated by the impact of the grinding inside the mill; this is converted into an output signal that can be used to control the material feed rate into the mill.

After simple calibration the Millminder ensures that mill feed is properly regulated. Should it become too high or low, the system will adjust accordingly to meet the demands of the plant. Benefits include having a more uniform grind, elimination of clogging and minimised wear on the mill liner.
