Problems

Optimisation of crushing circuit

Irregular ore enters circuit from stockpiles and bunkers

Coarse and unsteady ore feed enters HPGR circuit that degrades its productivity

Grizzly choking occurs regularly that creates production bottlenecks

Operator can’t manually respond to changes in grinding circuits for optimal results

Digital Advisor for Crushing Process Control

Solution

Model predicts ore class upon exit from the circuit 30 minutes in advance

Virtual sensors monitor ore in bunkers to help operators prepare for irregularities in advance

Digital advisor recommends optimal grinder settings

Tracks movement of ore in circuit and evaluates granularity in real time

Result

Increase in  throughput
