The circuit consists of a 34 x 20 EGL SAG mill, a Raptor 900 pebble crusher and two 24 x 396 ball mills. Each mill is equipped with a 2 x 8500HP dual pinion drive system. The plant was designed to process 1585 h mtpof SAG feed. From startup, the mill struggled to meet the required production rates.
In a mining plant or processing mill, they have a big grinding circuit for crushing raw material, these are usually Ball or SAG mills. Inside these SagBall mill are big steel balls that grind ore via an impact process. In simple terms, these hard metal steel balls get to the top of the rotating chamber and fall down crushing the ore being ...
SAG milling extends itself to many applications due to the range of mill sizes available. They can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill and some or all of the work done by a ball mill. SAG mills are also an optimum solution for wet grinding since crushing and screening in these ...

Mill Type Overview. Three types of mill design are common. The Overflow Discharge mill is best suited for fine grinding to 75 106 microns. The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 250 microns. The Center-Periphery Discharge mill has feed reporting from both ends and the product discharges ...
F80 to P80. Therefore, a really energy-efficient circuit may mean three stages of grinding instead of only two, and each stage can be slightly smaller and more efficient than one big one, e.g. a SAG mill or HRC followed by a ball mill and with a tertiary Vertimill.
