CalculateTopBall Sizeof Grinding Media -FRED C. BOND Equation & Method Previous Next Although it was developed nearly 50 years ago, Bond ‘s method is still useful for calculating necessarymillsizes and power consumption forballand rodmills.
Ball Mill Power CalculationExample #1. Awet grinding ball millin closed circuit is to be fed 100 TPH of a material with a work index of 15 and asizedistribution of 80% passing ¼ inch (6350 microns). The required productsize distributionis to be 80% passing 100 mesh (149 microns).
Thesizingofball millsandball milling circuitsfrom laboratory grinding tests is largely a question of applying empiricalequationsor factors based on accumulated experience. Different manufacturers use different methods, and it is difficult to check the validity of thesizing estimateswhen estimates from different sources are widely divergent.
A) Total Apparent Volumetric Charge Filling – including balls and excess slurry on top of theballcharge, plus the interstitial voids in between the balls – expressed as a percentage of the net internalmillvolume (inside liners). B) Overflow DischargeMillsoperating at lowballfillings – slurry may accumulate on top of theballcharge; causing, the Total Charge Filling Level to be ...
Jun 25, 2018· 335 is a constant used for dry grinding with steel balls in the mill. Actual size of media is taken is lower than the calculated value. It is around 80 to 90 mm. If you Wants to reduce the maximum ball size, thenreduce the feed size by using pre-grinding operation.
