For the mining industry, our semi-autogenous (SAG) grinding mill uses a minimal ball charge in the range of 6-15 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media.

Steady state and dynamic simulation of a grinding mill

Steady state and dynamic simulation of a grinding mill

Jun 15, 2020 A significant challenge when modelling grinding mills is to separate the characteristics of the ore from the characteristics of the grinding environment (Powell and Morrison, 2007). This is especially true for models of the breakage rate as the models have to represent the full range of operating conditions given by the grind curves.
