An update on Comminution '25

It was interesting to hear that one of the Comminution '25 sponsors, Weir Minerals, a global leader in innovative mining technology, has launched the all-new ENDURON® Orbital range of vibrating screens. Engineered for sand and aggregate, construction, and small tonnage mining operations, the new screens are designed to meet the most demanding of applications as they feature an all-bolted construction, significantly improving reliability by eliminating welding in high-stress areas, the leading mode of failure in vibrating screens.

Screens are replacing classifiers in many grinding mill circuits as classifying by size-only they give a sharper separation than hydrocyclones with multidensity feeds and reduce overgrinding of the dense minerals. and another leading manufacturer, Derrick Corporation, also a Comminution '25 sponsor, will also be highlighting their new developments in this area,

New comminution and classification technologies are regularly hitting the market with promises to reduce energy, improve liberation and reduce costs, but Grant Ballantyne, a Technical Director at Ausenco, Australia, will ask, in his keynote lecture at Comminution '25, how can we identify the fine wine from the snake oil? For example, improved energy efficiency can be achieved at the detriment of wear, or improved liberation can be achieved without improving recovery. What is the truth behind the curtain? And how can we find this truth as quickly and efficiently as possible? Grant's presentation will explore the range of evaluation methodologies that are available, as well as some lessons that can be learned from previous ineffective assessments.

Grant is also a Director of CEEC, one of the conference's industry advocates and he is an Adjunct Associate Professor at the University of Queensland. In 2019 he won the CEEC medal and in 2017 was awarded the MEI Young Person's award.

Things are looking good for Comminution '25. Abstracts are already coming in and 20 companies are signed up for sponsorship, the latest being Maelgwyn Minerals Services and Molycop.
