How to Measure the Impact Forces in Ball Mills
Final ball diameter was 140mm. The test ball must be substantially larger than standard 75mm balls in the Climax mills to be easily recovered and minimize chance of loss in the ball charge. The ball was machined from alloy steel shafting and weighs 7.14kg with 6 accelerometers.

Fill-Level Measuring Device for Coal Mills
KIMA Echtzeitsysteme’s fill-level measuring device, used for ball mills in the cement industry for over seven years, has now been adapted and developed for use in coal mills. A new fill-level sensor enables reliable fill-level measurements, even with fluctuations in coal quality or moisture levels.
Mill Steel Charge Volume Calculation
The % loading or change volume can then be read off the graph below or approximated from the equation and calculation: % Steel Charge Loading in Mill = 113 – 126 H/ D. Ball Mill Charge Volume Calculation. Charge Volume of a Grinding Mill (Method 1) Charge Volume of a Grinding Mill (Method 2)

Depending on the height of the material bed, the grinding media inside the Ball Mill causes a characteristic noise. In case of high material bed (max. filling level), there is hollow grinding sound (low volume & low grinding frequency), where as for low material bed (min. filling level), there is high pitched sound (high volume & high grinding frequency).
Optimization of mill performance by using
previously, at a mill stop, the measurement of ball charge filling degree could be undertaken and will provide the static media charge angle (βstatic = 143°). An online measurement of the similar angle (βdynamic), when the mill is running, provides information about the dynamics of the charge.

The foam of the Electronic Ear must nearly touch the mill shell between two rows of bolts. The head of the micropone is 4-5 cm in the rear, and is protected by a fine grid covered by a thin stone film at the level of the foam coat. Therefore, fitted in foam, the microphone is insulated from the interfering noises existing in the plant.
