Newton Fund - SAG Mill Optimisation and Innovative Instrumentation Development

点击翻译按钮获取中文摘要

This experimental demonstration will be conducted at one of the world’s largest grinding mills operated byMinera Centinela. It will demonstrate the feasibility of applying modern computing and simulation technologiesto create a process model that can be used to optimise operations. A robust environmentally friendly wirelessinstrument, which can accurately predict charge in real time in high granularity, will be demonstrated. Tosustain current levels of copper production Chile must overcome a number of challenges; increasing energycosts; declining ore grades; increased throughputs; harder, more variable and complex ore types. This projectwill show how geometallurgical information can be used to predict the properties of the SAG Mill feed and,dynamically model operational performance to provide optimal set point recommendations for energyoptimisation. The model will also monitor wear rates to produce a predictive maintenance schedule therebyminimising costly unplanned shutdowns.
