The discharge grates of the SAG mill were identified as a key component in the SABC circuit, and their design is a crucial factor in the mill's performance [17,18,19,20,21]. The initial design of the grate section caused a serious accumulation of pebbles within the SAG mill which contributed to a decreased grinding efficiency.

In mineral flotation, rheological problems have limited the efficient upgrading of low-grade and complex ores. Since pulp and froth rheology are deemed to play different roles in influencing the separation performance, in this paper, a brief review on pulp and froth rheology in flotation is provided, with an objective of developing a basic understanding of rheology in flotation.

Grinding circuits reduce ore to sub-millimeter sizes, an extremely energy intensive process. As a result, the majority of a plant's energy cost is normally spent here. They are also asset intensive. The high impact, abrasive environment is challenging to equipment making maintenance costs and mill stoppages a big factor.

Depending on the size of the mill and whether or not there is a trommel on the mill discharge, you can throw (hand-bomb) balls in from the discharge end of the mill, or you can install a 6" long radius pipe that will let you roll the ball into the mill, this can save on the muscle building, but needs to be a mobile structure so it can be removed during relining.
