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

Ball Mill Wikipedia A ball mill a type of grinder is a cylindrical device used in grinding or mixing materials like ores chemicals ceramic raw materials and mills rotate around a horizontal axis partially filled with the material to be ground plus the grinding medium Different materials are used as media including ceramic balls flint pebbles

Live ChatThe sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods, and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent. It is especially difficult to teach mill

Live Chatmeasurement or the percentage by volume of balls in the mill. This is usually performed soon after a crash stop. The basic principle is to measure the height H from the charge to the shell and the internal mill diameter Di. By calculating the ratio H/Di and using the graph below (Figure 1), the charge filling degree in volume

Live ChatBall volume in total mill load could compute by Equation 3. Mill Ball (%) = 100{[(ball volume in the 0.4 m3 sample)* 58.52] / 0.4}/297.96 (3) According to the results (Table 1), the ball filling percentage was obtained 1.3%. However, these results may have some field errors
