calculating volume of grinding media charge
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 and
THE GRINDING CHARGE OF ROTARY MILLS
Vinc = the volume of charge, Vcm = grinding media or volume, Minc = weight of the charge, Mcm = weight grinding media, ( Minc ≈Mcm), ρ= the density of the material of grinding media, ρcm = bulk density of grinding media. Bulk density of grinding media can be determined (if ρ and ε are known), with the relation ρcm =ρ(1 −ε) (2)Онлайн-запрос
