Dynamic Modeling and Simulation of SAG Mill Circuits with

crushers, respectively, but only a few have investigated the dynamic interactions between a SAG mill and its pebble crushers. The scope of this thesis is to examine the dynamic relations between the SAG mill and the pebble crusher in a closed circuit and thus to optimize the circuit efficiency by controlling the pebble crusher operational settings. In this thesis, two modeling techniques are proposed for simulating the dynamics

Dynamic modeling and simulation of a SAG mill-pebble

01-10-2018· The simulation results suggest that the total charge load in the mill could be from 454 tonnes up to 510 tonnes, depending on the cone crusher’s settings. All these simulation results presented in Fig. 9 show that the cone crusher’s settings have a significant impact on the mass flow in a SAG-cone circuit.

Dynamic modeling and simulation of a SAG mill-pebble

To verify this hypothesis, a dynamic model of a SAG mill-pebble crusher circuit was implemented. The dynamic unit models are based on results presented by several different researchers, whose results here have been combined and implemented in Matlab/Simulink. Previous research shows that by controlling the cone crusher operational parameters, the product particle size distribution (PSD) can be altered

Crusher Dynamics, Design and Performance

Longer fractions results in higher crushing pressure and better particle shape. Single particle breakage requires lower crushing force compared to interparticle. If the crushing angle is small you can experience packing even at low power draw. Capacity is controlled by choke area. Higher eccentric speed results in more compressions and
