Nowadays ball mills still dominate secondary grinding applications, but are increasingly in competition with closed circuit AG/SAG mill circuits and stirred mills (NapierMunn et al., 1996). At product sizes finer than 80% passing 75 μm, the efficiency of ball mill grinding rapidly decreases.
Earlier work by Fuerstenau and Kapur on the comminution of quartz in a singleparticle roll mill and in a dry ball mill showed the energy efficiency of ball mill comminution to be 22%. Thus, as a mechanical device for producing fine particles, the ball mill is reasonably efficient energetically.
Fine grinding of taconite for the liberation of ironcontaining minerals is very energyintensive. This investigation has shown that a highpressure roll mill is significantly more energyefficient than the traditional ball mill. Further energy efficiency can be achieved by grinding taconite in a ...
The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultrafine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then being separated, and the coarse part being returned to the mill inlet.
