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 Napier-Munn, 2006, Ye et al., 2010), or more simply "shear" breakage (Radziszewski, 2013).The dominant breakage mechanism in ball mills is generally …
A magnetite middling was used to compare the liberation effect of the magnetite fine ground by a vertical stirred mill and a ball mill. The magnetite middling contained a high content of magnetite intergrowth with the particle size mainly distributed in the range of 40–150 μm.The new generated −38 μm products were concentrated by …
The ball mill is a rotating cylindrical vessel with grinding media inside, which is responsible for breaking the ore particles. Grinding media play an important role in the comminution of mineral ores in these mills. This work reviews the application of balls in mineral processing as a function of the materials used to manufacture them and the …
