China Ball Milling Machine/Rod Mill for Gold Ore Grinding . They are also different in the grinding form of grinding medium. The crushing process of rod mill is realized by line contact between rods. Thus the crushing is selective, and then small ones. So, compared to ball mill, the fineness of final products processed by rod mill is even. 1.

2016-8-1 Use of a rod mill was justified based on previous research, indicating gold particles subjected to grinding in a ball mill were effectively flattened (Ofori-Sarpong and Amankwah, 2011), while rod mills preferentially grind larger waste particles over fine gold particles (Wills and Napier-Munn, 2006). This method, while currently used at a ...

2016-5-31 ROD MILL CAPACITIES. The above tables list some of the most common Open End Rod Mill sizes. Capacities are based on medium hard ore with mill operating in closed circuit under wet grinding conditions at speeds indicated. For dry grinding, speeds and power are reduced and capacities drop 30 to 50%. ROD MILL

The circuit consists of primary, secondary and tertiary crushing, rod/ball mill grinding, gravity concentration, cyanide leaching, carbon-in-pulp gold recovery, stripping, electro winning and refining. Gravity gold is recovered by the use of five Knelson CD-30 Concentrators fed from the cyclone underflow.
