The ball mill is a tumbling mill that uses steel balls as the grinding media The length of the cylindrical shell is usually 1–1 5 times the shell diameter (Figure 8 11) The feed can be dry with less than 3% moisture to minimize ball coating or slurry containing 20–40% water by weight

Ball mill A typical type of fine grinder is the ball mill A slightly inclined or horizontal rotating cylinder is partially filled with balls usually stone or metal which grind material to the necessary fineness by friction and impact with the tumbling balls Ball mills normally operate with an approximate ball charge of 30%

Simulation of a ball mill operating with a low ball charge level and a balanced ball size distribution It was operated with a ball charge equal to 20% (J=0 2) powder filling (voids between the balls) equal 50% (U= 0 5) and ran at 70% of the critical speed A new laboratory test was conducted with torque mill considering a 15% ball

 A) Total Apparent Volumetric Charge Filling – including balls and excess slurry on top of the ball charge plus the interstitial voids in between the balls – expressed as a percentage of the net internal mill volume (inside liners) B) Overflow Discharge Mills operating at low ball fillings – slurry may accumulate on top of the ball charge causing the Total Charge Filling Level to

Abstract: The question about modern intelligent information processing methods usage for a ball mill filling level evaluation is considered Vibration acceleration signal has been measured on a mill laboratory model for that purpose It is made with accelerometer attached to a mill pin

Since delivery time for parts to repair the damaged drive was lengthy a decision was made to reduce the charge in the ball mill from approximate 32% filling level to a point low enough to allow the mill to be operated with the single remaining drive Surprisingly the result was a minimal loss in production with a significant gain in efficiency
