• Improving The Efficiency Of Fine Grinding

     · The use of ceramic beads as grinding media within high intensity stirred mills (such as the IsaMill) is desirable to maximise the energy efficiency of these processing units. Using a ceramic media with properties tailored to high intensity stirred milling further increases energy efficiency and extends the practical operating range of these mills to coarser feed and product sizes. Historically the economics of using ceramic media types in stirred mills in the minerals industry has not been attractive. Magotteaux International and Xstrata Technology cooperated in the testing and product development of a new ceramic media known as Keramax MT1 designed specifically for the minerals industry. Comparative media consumption tests are described and show how the low wear rate and high efficiency of this new ceramic offers an economic alternative to existing media types. The paper proposes the sliding friction coefficient as a new tool in characterising stirred milling grinding media. The first application of this ceramic
