Dynamic modeling and simulation of cone crushing circuits ...

Abstract As a common practice, steady-state models are used for simulation and process dimensioning of crushing circuits. However, intended circuit performance is rarely achieved due to constantly fluctuating feed-material size and characteristics. This gap between theoretical and realized performance has the potential for process control. Little scientific attention has been paid to the ...
