Integrated Approach to Monitoring and Control of Mineral Grinding Processes

Abstract

To enhance the operation of mineral grinding processes, a greater number of monitoring services and control schemes are nowadays being offered by the equipment manufacturers. In this paper an integrated approach to grinding process monitoring and control is formulated and the components of the integrated automation for typical grinding processes are proposed. Furthermore, the benefits of the process monitoring services are studied on the basis of a specific case study -the Outokumpu Chrome Kemi concentrator. Finally, the results are discussed and a new control scheme is outlined.

Performance Audit of a Semi-autogenous Grinding Mill Circuit

“…In minerals engineering, and communition in particular, the semi-autogenous grinding mill (SAG mill) is an operational unit where many problems may lurk. A suitable overview of historical data should prove useful, indeed (Remes et al 2006).…”

Grinding in Ball Mills: Modeling and Process Control

“…Simulation results with expert system based control, supervisory control and observer based control are reported in [9,11,12]. An integrated automation system for monitoring and grinding process control is designed in [41] and a neurocontrol approach is developed in [13].…”
