How SAG Mills Work in Copper Ore Mining. SAG mills are a critical component of copper ore mining, as they play a vital role in grinding the ore into smaller pieces that can be further processed. These mills are typically large and use steel balls to break down the ore into smaller particles.
The total energy consumption for ore comminution will further increase within the next decades. One contribution to minimise the increase is to use more efficient comminution equipment. Vertical-roller-mills (VRM) are an energy-efficient alternative to conventional grinding technology. One reason is the dry in-bed grinding principle.
The application of vertical-roller-mills (VRM's) for ore grinding is part of the second strategy. The grinding parts of a Loesche mill (Fig. 1) are a rotating table (1) with a horizontal grinding track and rollers (2), which are pressed onto the table by lever arms and a hydro pneumatic spring system.
