Single stage ball mill circuit

Single stage ball mill circuit

Ball mills are the most common grinding machine employed in the mining industry. Grinding occurs in a single stage, or multiple stages. Multiple stages may include a rod mill followed by a ball mill (two stage circuit), or a semi-autogenous grinding (SAG) mill followed by a ball mill (two stage circuit)

    crushing and single-stage ball milling circuit. Barratt, 1989, writes that a copper porphyry ore in a power-effi-cient circuit of SAG milling followed by ball milling should be 10% less efficient that the “maximum efficiency” grinding circuit (crushing, single-stage ball mill). Thus, the Etotal of a SAG and ball mill circuit is: Etotal=1.10

    nigeria used single stage fine ball mill. Ball mills are used primary for single stage fine grinding, regrinding, and as the second stage in two stage grinding circuits. According to the need of customers, ball mill can be either wet or dry designs. Ball mills have been designed in standard sizes of the final products between 0.074 mm and 0.4

    A leading Australian nickel mine has a grinding circuit comprising a primary single stage SAG mill in closed circuit with cyclones. The SAG cyclone underflow passes through a flash flotation before returning to the SAG mill. A portion of the flash flotation tails reports to a separate ball mill which helps to reduce load on the SAG mill

    Fewer mills are, however, easier to control and capital and installation costs are lower, so the number of mills must be decided at the design stage. The high unit capacity SAG mill/ball mill circuit is dominant today and has contributed toward substantial savings in capital and operating costs, which has in turn made many low-grade, high

    For this purpose, six Warman Cavex cyclones having 400 mm diameter were installed. Now, the combined primary and secondary ball mill discharge was classified in single stage with the Warman cyclones in closed circuit with the secondary ball mill. The cyclone overflow goes directly to the copper rougher circuit as flotation feed

    The regrind circuit will consist of a single stage ball mill in closed circuit with a hydrocyclone cluster. Flotation tailings will be directed to a high rate thickener to increase the density of the slurry prior to regrinding. Flocculant will be pumped to thickener feed and diluted (by a factor of ten) before addition

    Apr 19, 2016 Closed circuit crushing is recommended for single stage grinding as there is greater control over size of feed going to the one ball mill. Open circuit crushing is advantageous when using two-stage grinding due to the ability of the rod mill to handle an over-size feed product.
