November tech talk: Real-Time estimation of SAG mill charge characteristics for process optimisation

Join the Kalgoorlie Branch for their November tech talk: Real-Time estimation of SAG mill charge characteristics for process optimisation with Paul Toor, Comminution Consultant at Toornado Metallurgy.

About this event

This presentation is based on a paper of the same name co-authored with Dr Walter Valery (Hatch), Mrs. Kristy Duffy (Hatch) and Dr Steve Morrell (SMC Testing), whose mill power draw model (Morrell C-model) is used as the basis of analysis in the work.

The presentation aims to empower metallurgists to leverage available process and plant data and couple it with the Morrell C-model to gain valuable real-time insights into SAG charge characteristics for process optimisation. 

Three approaches, supported by case studies are shared, that enable metallurgists to:

• Infer mill filling and ball charge with higher confidence
• Analyse large-scale and real-time process data
• Detect and troubleshoot mill performance issues early

With advancements such as mill-mounted sensors, VBA integration, and high-resolution laser scanning, Paul demonstrates how real-time charge estimation can improve plant operations.

This presentation will be valuable for plant metallurgists, process engineers, and mining professionals looking to improve comminution efficiency and operational decision-making.
