Crushing plants are a vital part in the production of aggregates and metals. Plants are traditionally simulated with a steady-state simulation. With steady-state simulation the plant is simulated until equilibrium is achieved. However, crushing is a continuous process and as such it is subjected to variations and changes in performance depending on the dynamics of the system. A different technique is therefore necessary to estimate the real behaviour of the plant.
The main hypothesis in this research is that crushing plants are affected by both gradual and discrete changes in the process which alter the performance of the entire system, making it dynamic. A dynamic simulation is defined here as continuous simulations with sets of differential equations to reproduce the dynamic behaviour of a system. Crushing plants experience different operating performance depending on the configuration of each individual process unit, the configuration of the plant, the design of the control system, events occurring in the process and additional disturbances.

There are number of different factor that can affect the performance of the plant and cause it to experience dynamic behaviour. These can be Material related factors, production unit related factors, operational related factors and material handling. These can however change gradually, discrete and even have a dynamic respond.
