    Analysis of power draw in ball mills by the discrete

    Apr 01, 1999 The calculated power draft is maximum at about 50% ball load. According to Eq. 1, mill power is a function of ball mass (M b) and the distance between mill center and the center of gravity of ball mass (r g). So, as the mill filling increases M b goes up, but r g decreases. Therefore, the power draft passes through a maximum

    8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight

    Optimization of mill performance by using

    Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between mill absorbed power and ball filling degree. As indicated on
