Extended milling/mechanical activation properties of zinc plant residue was investigated using two different milling systems, namely, high speed vibrating ball mill and ring mill, comparatively. The zinc plant residue was mixture of gypsum, anglesite, massicot, quartz, maghemite, and franklinite. Zinc plant residue was milled for 1–30 min …
On the contrary, the number of steel balls are small, the grinding strength is also small. In terms of mechanics phenomena, the more steel balls in ball mill,the bigger consumed power of ball mill, the bigger ball mill productivity. Besides, there are mine and water in ball mill, so the practical power is different with idea power in a gap.
