Understanding Different Perspectives of Dynamics in Comminution Processes

• The performance of a comminution and classification process depends on the design and configuration of each process unit, the configuration of the plant, the design of the control and physical properties of the incoming feed. Comminution processes should be designed to have a stable and efficient production over a wide range of conditions. However, demands from the management, operational cost, investment, maintenance or any other related field can result in process alterations that are not beneficial for the stability of the circuit and therefore utilization and efficiency of the production. Furthermore, advanced process control and optimization rely heavily on understanding the dynamic behavior of the process in achieving a more stable and consequently efficient process. The objective of this review is to explore different dynamic aspects from particle, bulk, unit and process perspectives, their origin, and what consequences they may have on the operation. The aim is to illustrate a holistic view of process dynamics that should be considered when evaluating circuit performances and identifying risk zones that affect the process, both considering the state-state performance as well as the dynamic behaviour.
