The evolution of the Ernest Henry SAG mill liners is shown in Table 8. The SAG mill was initially supplied with ME International rail bar design liners as specified in Table 8. These liners cracked longitudinally along the liner plate portion adjacent to the lifter rail after approximately three months of operation. This breakage

The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 10%-15% above the ball charge for total of 23% ...

Ore hardness plays a critical role in comminution circuits. Ore hardness is usually characterized at sample support in order to populate geometallurgical block models. However, the required attributes are not always available and suffer for lack of temporal resolution. We propose an operational relative-hardness definition and the use of real-time operational data to train a …

Material is crushed underground, stockpiled and then conveyed to a 6.1 x 4.1-m SAG mill. It is powered by a 2.3-MW motor and runs with 8%-12% of the mill's volume filled with 125-mmdiameter steel grinding balls. Incoming ore varies in zinc and lead levels and hardness. The SAG mill therefore operates at variable speeds.
