In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or millBall mill media optimization  Metcom Tech,plant ball mill’s grinding efficiency (Fig. 1). The functional performance parameters “mill grinding rate through the size of interest,” and “cumulative mill grinding rates” from both plant and smallscale tests are applied to this task. A plant media sizing methodology, andball mill sizing and design  pizzastation.fr,Design parameters of ball mill The ball mill is a tumbling mill that uses steel balls as the grinding media The length of the cylindrical shell is usually 115 times the shell diameter Figure 811The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing % water by weight.

Read MoreSize by size cumulative energy specific grinding rates can be used to characterize mill grinding performance and changes in performance, as a function of media sizing. They can be used for both plant and test mill data. The cumulative grinding rate through the size of interest is the identical parameter as the ball mill grinding rate calculated from the functional performance equation. Its maximization is the technical optimization criterion for ball sizingHow to Size a Ball Mill Design Calculator & Formula, 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,calculation for grinding media in ball mill osk9e,Ball mill media optimization  Metcom Tech. plant ball mill’s grinding efficiency (Fig. 1).

From this plot, it is shown that a target fineness of 80% < 2 microns is normally achieved in 315 minutes of recirculation milling with 1.0 to 1.4 mm grinding media. By reducing the media diameter to 0.6 to 0.8 mm after 90 minutes, the target grind is achieved in only 150 minutes.
