In an autogenous mill, the ore itself is used in the grinding process.ag mill isombination ofall mill and an autogenous mill. the main component of all mills isorizontal rotating drum, typically withubber liner and regularly spaced lifter bars see figure 1.
It can, therefore, be concluded that autogenous grinding was not suitable with this particular gold ore, but semiautogenous operation with aboutall charge was the preferred option. based on these test results,.7iameter 2.1ength sag mill and.3.1all mill were installed for commercial operation in closed circuit.
It is well known that the lifter profiles hitherto extensively used in the semiautogenous grinding sagautogenous grinding ag or the primary mills are lifter bars and trapezoid lifters.
Lifter spacing around the shell periphery has generally been satisfactory with the number of lifters at twice the inside shell diameter in feet. for example, on8 diameter mill there would be 56 lifters per circle. it has been found that these lifters provideefinite aid in the autogenous grinding action.

The experimental results showed that the abbottfirestone curve can evaluate the lifter surface topography. the wear rate of the lifter specimen is increased first and then decreased with mill speed and grinding media size. increasing ball filling will increase the wear rate, and the grinding media shape of ball hasaximum wear rate.
The general advantages in semiautogenous grinding sag mill liner are as follows in the recent 20 years, our liners have been widely used in large,medium and small ball mills in chinese power generation, mining, cement, chemical engineering and metallurgical industries and super fine pulverizing equipments.
The grinding balls are modeled as spheres and the mill shell is modeled asong cylinder and the exact geometry of the lifter bars is modeled with exact planar dimensions. the key simulation feature is that as the mill shell rotates, it imparts momentum to the spheres that are in immediate contact with the shell, and these spheres in turn.
