study of lifter wear and breakage rates for different

Sep 01, 2019· Lifter IV had the highest rate of breakage between 65 and 75% Nc mill speeds, however taking into account the values of rate of breakage at55%(0.00303 min −1) and85% (0.00619 min−1), it may be possible to conclude that there is a potential benefit to operate the mill at higher speeds than 55% using Lifter IV. This face angle creates a load profile that increases the rate of breakage at speeds …

Jan 01, 2016· Theball millfilling can be estimated from the geometry of theballcharge at rest. However, in terms of theangleθ,ballfilling (J B) may also be computed as indicated by Austin et al. . These relationships are illustrated in Figure 7.5. The charge centre of gravity may also be located in a similar graphical way as shown in Figure 7.6
