    Grinding Circuit Simulation - 911metallurgist

    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. This approach reduces the amount of input information and computation required in the simulation.
