These programs and the simulation algorithms are discussed below. Note that in some Grinding Circuit Simulations, a residence time distribution model is used.In the MRRC simulation package, however, only the two extremes of well mixed and plug flow through the mill are considered.
proposed flowsheet consists of existing SAG mill circuit followed by a new proposed ball mill in closed circuit with the existing hydrocyclone package. In all simulations, SAGT, CYCL and MILL models were selected to simulate SAG mill, Hydrocyclone packages and ball mill units.
In the case of ball mills, this is certainly not straightforward. Let´s consider a simple example: the most common tumbling mill test used in the lab is the Bond ball mill grindability test, used for nearly 70 years to determine the Bond work index, which is a number used to estimate how hard it will be to grind the material of interest.
