A mine-to-mill study was conducted to improve the grinding circuit operation and the main recommended actions included the use of a variable primary crusher closed-side-setting css depending on the ore type, control of the grinding media volume based on wear rates within the sag mill,.
Me elecmetals patented one point wear performance tracking system is an online tool that stores both current and historical operating parameters, and liner wear profile data.It predicts remaining liner life, allows for comparison of current vs.Historical wear rates and much more, all while drastically reducing measurement time.
Sag mill liners from multotec use rubber composite components to provide superior impact and wear resistance in all semi-autogenous milling applications.Steel inserts create high impact resistance specialised rubber absorbs impact energy.
Sag and ag mills operate by lifting oregrinding media and dropping it on the operating bed of the mill charge.High impacts from lifting ore and media promote impact breakage which is the primary mechanism for size reduction in the mill.

Video 1 mill showing surface wear modification case scenario.Consider a large sag mill with a diameter of 10.97 m, as shown in figure 1a.The mill has a high-definition line design with alternating lines of high and low elevators figure 1b.The mill processes rocks from 200 mm to 300 mm, using 350 mm steel balls as the grinding medium.
Within the mineral processing industry, a range of grinding conditions exists which include semiautogenous grinding sag, rod milling, and conventional ball milling.Each of these mill environments presents a unique environment for grinding media, requiring the application of specific physical and chemical properties for optimum grinding media performance.
The increased wear life of the shell lining from 70 to 75 days without breakage has been a big factor in the higher uptime.If the wear life is kept stable, we will use a half set of shell lining less per year.In order to help the customer to achieve these goals, metso continued in-depth studies to further optimize the sag mill linings.
