Typically this type of mill can deliver a product with a fineness of less than 0.1 mm. Testing of material is needed before hand to determine the suitability of the ore for processing in an autogenous mill. The rod mill (Fig 1) is a tumbling mill which is having a large percentage of its volume (30 % to 40 %) loaded with steel rods.

L = length in feet of grinding chamber measured between head liners at shell- to-head junction Many grinding mill manufacturers specify diameter inside the liners whereas others are specified per inside shell diameter. (Subtract 6" to obtain diameter inside liners.) Likewise, a similar confusion surrounds the length of a mill.

Ore processing is a 24 hour operation. Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along ...
