With more than 100 years of experience in ball mill technology Metso’s ball mills are designed for long life and minimum maintenance They grind ores and other materials typically to 35 mesh or finer in a variety of applications both in open or closed circuits

circuits at Palabora Mining Company Each milling circuit consists of a rod mill followed by a ball mill in series Crusher product 9 mm is fed to the rod mill and the water is fed in ratio to the ore feed mass The rod mill discharge is pumped without any further water addition to the first ball mill The ball mill discharges to a sump where water is

The industry best in energyefficient grinding the OK Mill uses five to ten percent less power than other vertical roller mills and 30 to 50 percent less energy than conventional ball mills Easy operation and maintenance Worn roller grinding surfaces can either be replaced or rewelded inside the vertical roller mill

The sulphide and mixed ores undergo twostage crushing in a primary gyratory and opencircuit secondary cone crushers while the oxides are crushed in a primary jaw crusher and a secondary sizer The grinding circuits comprise a SAG mill a ball mill and

The high unit capacity SAG millball mill circuit is dominant today and has contributed toward substantial savings in capital and operating costs which has in turn made many lowgrade hightonnage operations such as copper and gold ores feasible Future circuits may see increasing use of high pressure grinding rolls Rosas et al 2012
