## Calculate and Select Ball Mill Ball Size for Optimum Grinding

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 mill liner wear andNov 01, 2017· re Cement Mill Grinding Media Dear Sagarhbt, Why are you concerned about surface area? I never hear about basing your ball charge on surface area! In your first compartment the grinding is not related to surface area at all and it is related to weight and number of impactsCement Mill Grinding Media Page 1 of 1 Ball top size (bond formula): calculation of the top size grinding media (balls or cylpebs):Modification of the Ball Charge: This calculator analyses the granulometry of the material inside the mill and proposes a modification of the ball charge in order to improve the mill efficiency:Ball charges calculators thecementgrindingoffice

## Ball Charge and Grinding Efficiency Grinding

The volume of grinding media in a mill is directly related to grinding efficiency The higher the volume of grinding media the more effective the grind Balls must be added to maintain the media load and mill power draw The power draw increases as balls are added and decreases as mediaterms of energy requirements and steel consumption related to grinding media and liners Spherical grinding media are predominantly used in final stages of ore grinding The spherical balls change shape through breakage and wear Though this is universal in milling, its contribution and effect on milling kinetics, load behaviour and mill powerEFFECTS OF GRINDING MEDIA SHAPES ON BALL MILLof grinding media (bringing of the specific charge value to the initial size, by adding new grinding media), produces the increasing of the throughput of mill with 15 or even 30 % [1] Taking in consideration the specified facts, it appears as necessary the control and adjustment of the specific charge of the drum with grinding mediaTHE GRINDING CHARGE OF ROTARY MILLS
