Computer simulation of ball mill cicuits has been found to be very valuable for optimisation where existing plant data can be used to calibrate the mathematical models used. However, as by definition no existing plant is available for calibration in greenfield scenarios, the use of simulation in ball mill circuit design has been limited.

Crushing Plant Flowsheet DesignLayout. In the crushing section, the ore as it comes from the mine is broken down dry to a size suitable for the wet grinding machines ; these can, if necessary, be made to take lumps of 2in. size, but they work much more efficiently if their feed is ½ in. or less. Before the advent of the Symons cone crusher ...

Ball mills are suitable for low and medium moisture content in the range of five to six percent and are preferred for abrasive material. The main advantage of VRM is higher grinding efficiency and the ability to accept material with higher moisture content. Normally the energy consumption level in VRM is 10 to 20 percent lower than in ball mills.
