The fill level of the ball mill is optimised according to the production requirements. The fill level is measured by an electronic ear. Our new system captures a broad spectrum of frequencies which simplifies the filtering of external sources such a neighbouring mills. The ear measures and memorises the frequencies of each mill.

Technical specifications:

• Robust and compact housing
• Diaphony for up to 6 ball mills measured simultaneously
• Mill level displayed by bargraph for each ball mill
• Directional microphone in damped mounting
• Maintenance free
• Memorisation of 15 optimised noise levels
• Microphone sealed against dust, IP65
