Mill liners fill a basic role: to protect your mills from the intense wear and tear that comes from grinding down hard, raw materials. But even if they all do the same job, not all mill liners are created equal. From the abrasion resistance of rubber to the impact resistance of steel, different material parts offer different advantages. FL supplies the full range of mill liners options ...

Ball mill - A steel cylinder filled with steel balls into which crushed ore is fed. The ball mill is rotated, causing the balls to cascade and grind the ore. Banded iron formation - A bedded deposit of iron minerals. Basalt - An extrusive volcanic rock composed primarily of plagioclase, pyroxene and some olivine.
The mine production schedule delivers 24.9 Mt of ore grading 1.34 g/t gold to the mill over the LOM. Waste tonnage totaling 106.5 Mt will be placed in the waste rock dumps. Processing will include 2-stage crushing (jaw crusher and cone crusher) and 2-stage grinding (semi-autogenous-grinding mill and ball mill), resin-in-leach ("RIL ...
Planetary ball mill is a most frequently used system for mechanical alloying since only a very small amount of powder is required. Therefore, the system is particularly suitable for research purpose in the laboratory. The ball mill system consists of one turn disc (turn table) and two or four bowls.
Comment (Location): The Candelaria mine is located in the Candelaria Hills, about 15 miles south of Mina.
