Semi Autogenous Grinding Mill. Wet or dry; Higher capacity than A G mill grinding; Primary, coarse grinding Grinding media is grinding feed plus 4 12% ball charge High capacity Less sensitive to feed composition Semi Autogenous Mill
20/02/2017· The CRRK series of wet grinding ball mills are tabulated below. PEBBLE MILLS. No steel grinding media is used in a fully autogenous mill. When choosing primary autogenous grinding, run of mine ore up to 200 300 mm in size is fed to the mill. When using a crushing step before the grinding, the crusher setting should be 150 200 mm.
01/01/2016· Some dry autogenous mills operating in Canada are 8.5 m in diameter and 1.5 m in length. These are known as Aerofall mills. The Cadia Hill wet SAG mill is 12.2 m in diameter with a 20 MW motor and in 2004 was the largest diameter mill in operation in the world.
Ball Mill Application and Design. Ball mills are used the size reducing or milling of hard materials such as minerals, glass, advanced ceramics, metal oxides, solar cell and semiconductor materials, nutraceuticals and pharmaceuticals materials down to 1 micron or less. The residence time in ball mills is long enough that all particles get ...
