The breakage mechanisms in stirred mills regardless of the mill orientation are typically described as abrasion and attrition (Gao and Forssberg, 1995, Sinnott et al., 2006, Wills and NapierMunn, 2006, Ye et al., 2010), or more simply "shear" breakage (Radziszewski, 2013).The dominant breakage mechanism in ball mills is generally considered to be impact breakage in the toe of the ...

The experiments included a set of batch dry grinding procedures. The testing process was carried out with different types of grinding aids at different dosage ratios of g/t and at the same milling conditions as determined in a previous study [24] shown in Table 3, so that the differences caused by the operational alterations were minimized.

In Fig. 1 C, grinding iron ore only produced the finest fraction, followed by the 25 % quartz and 75 % iron ore ratio, equal quantity of the two ore samples, and only quartz material. The 75 % quartz and 25 % iron ratio yielded coarser fractions than quartz only in the range of 150300 µm. It is evidently observed that the addition of quartz mineral with increasing percentage tend to reduce ...
