Oct 14, 2015 The majority of grinding balls are forged carbon or alloy steels. Generally, they are spherical, but other shapes have been used. The choice of the top (or recharge) ball size can be made using empirical equations developed by Bond (1958) or Azzaroni (1984) or by using special batch-grinding tests interpreted in the content of population balance models (Lo and Herbst 1986)
mm +1.4 mm for the experiment. A mill run having a mixture of the 3 ball diameter sizes was also conducted. It was determined that the 30 mm diameter balls were most effective of the three sizes during the grinding of the 3 mono-size feed material samples. The 10 mm diameter balls were the least effective as minimum particle breakage was
Aug 02, 2013 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 tear
We investigated tlte effects of ball diameter and feed size on the rate constant when the ball mass, feed mass, and the mill's rotational speed were constant. The results indicated that the grinding rate constant can be expressed by modifying the equation that was proposed by Snow as the function of ball diameter and feed size. 1
Apr 01, 2021 The effect of ball size on the grinding kinetics of nepheline syenite in the ball mill was investigated. According to the dry grinding results of nepheline syenite, the ball diameter followed the first-order breakage law with constant normalized primary breakage distributions
Fig. 10 shows the effect of these two parameters on the optimum. composition of the make-up balls when grinding a feed of 90% pass-. ing 9.5 mm at a size reduction ratio of 45:1 using a 1 m

SIZE: SAG milling grinding media are available in sizes from 4.0” to 6.5” or 105 mm to 160 mm. CHEMISTRY: The chemistry of the balls is controlled via a robust internal quality system with our bar suppliers to optimize physical properties
Jun 01, 2018 For this coarser feed the 50 + 20+10 mm ball diameter mix breaks the material at a faster rate compared to the other ball matches. The availability of a ball size for a particular feed size ensures breakage occurs at a faster rate. The 10 mm ball size is unable to nip the large particle size hence the breakage rate is slower
Jun 01, 2012 sizes of the balls ranging from 10 to 150 mm in diameter [30]. Cylpebs are slightly tapered cylindrical grinding media with rounded edges and equal length and
