DYNAMIC MODELLING OF A SAG MILL-PEBBLE CRUSHER CIRCUIT …

In a semi-autogenous grinding (SAG) mill and pebble crusher circuit, the behaviour of the comminution process is non-linear and time-varying due to wear and variations in the feed material. To describe such a complex system, data-driven models were introduced, along with a case study of a SAG mill circuit in Copper Mountain, British Columbia, Canada.

The hypothesis put forward in this paper is that active control of the cone crusheru27s eccentric speed and closed side setting (CSS) can increase throughput and/or energy efficiency of the SAG circuit. To verify this hypothesis, a dynamic model of a SAG mill-pebble crusher circuit was implemented.

Grinding Circuit - an overview | ScienceDirect Topics

The crusher in closed circuit is then used to reduce the size of the critical size material and return it to the mill. As the pebble ports also allow steel balls to exit, a steel removal system (such as a guard magnet, Chapters 2 and 13 Chapter 2 Chapter 13 ) must be installed to prevent them from entering the crusher.
