Dynamic simulation of grinding circuits

A flexible and powerful dynamic simulation approach to grinding circuit simulation has recently been developed in CSIRO Minerals The MATLAB/SIMULINK graphical programming environment has been used to construct a library of dynamic mathematical models of a number of key grinding and separation devices and to link them into various complex dynamic grinding circuits...

Modelling cement grinding circuits

Modelling cement grinding circuits 1475 With further studies at different plants the relationship between the model parameters and the design and operating conditions was obtained The change of d5o, with the ratio of rotor speed to the air velocity to the separator exhibits a linear relationship which is shown in Figure 7...

Comparison of HPGR

To support the base case, the existing circuits were fitted and simulated using a JK SimMet® model Specific energy requirements for the proposed HPGR - ball mill circuit and HPGR - stirred mill circuit were determined from a pilot-scale HPGR and stirred mill test, in ,...

Grinding Circuits

Initially faced with a blend of primary and oxide ore, the circuit achieved in excess of 320tph until the oxide was depleted, leaving only the much harder primary feed The 20MW semi-autogenous grinding (SAG) mill and 37MW ball mill was assisted by a 150kW pebble crusher, but the power limitation of the SAG mill resulted in a drop in throughput...

Energy and Cost Comparisons of HPGR

The Huckleberry mine, located in British Columbia, produces roughly 40 million lb/y of copper A comprehensive energy and cost study compared an existing SAG mill-based circuit at the Huckleberry mine with two proposed circuits involving comminution technologies that are associated with energy efficiency: high-pressure grinding rolls (HPGR) and high-speed stirred mills...
