Toward Operation Improvement of HPGR and Ball Mill Circuits Through the Dynamic Optimization and Mill Speed Control in Response to Variation in Measurable Process Variables

Crushing and grinding processes are the largest consumers of energy at a mining operation. The High-Pressure Grinding Roll (HPGR) has gained popularity because it is much more energy efficient than conventional processes. The HPGR product is then ground in ball mills to prepare ore for mineral separation. These processes are controlled to optimize their performance […]
