Wednesday 2nd April
This morning's keynote lecture was given by Grant Ballantyne, of Ausenco, Australia. who I had the pleasure of presenting the 2017 MEI Young Person's Award at Comminution '18. Grant's keynote was the first of 16 presentations during the day, which will all be summarised in a couple of weeks' time.
FLSmidth (FLS) has for many years sponsored MEI Conferences. Their team of 5 has representatives from South Africa and Australia, who are highlighting the company's cutting-edge milling solutions, including the VXPmill, a high-intensity, energy-efficient stirred mill designed for ultra-fine grinding.

Following a long-standing relationship, an Indian mining customer has awarded FLS with the largest single order for the world’s largest size steel media tower mills. The mills are to be delivered at what is set to become one of the largest and most efficient iron ore beneficiation plants globally, reinforcing FLS’s global leadership in energy-efficient grinding technology.
The order includes the delivery of 18 vertical FTM-5000 tower mills to be used in both the secondary and tertiary grinding circuits, directly downstream from two of the world’s largest high-pressure grinding rolls, which the customer ordered from FLS in 2024. Each of these vertical grinding mills will be the largest steel media mills ever deployed in terms of both size and capacity. In addition to these mills, the order also includes the delivery of 30 KREBS UMD pumps and 18 KREBS gMAX hydrocyclones to complete the secondary and tertiary grinding circuits’ process requirements. The slurry pumps will be the largest known size of slurry pumps in all of India mining. The equipment is expected to be installed and commissioned during 2026/2027.
Italian company Eracles - Ceramiche Tecniche have produced sinterised alumina grinding balls and mill linings called ERALOX since 1993. In 2000 the company joined the Torrecid Group and have been producing in China since 2012. Eracles first attended an MEI Conference when they sponsored Comminution '23. It is good to have them back as sponsors of Comminution '25, their three representatives shown below talking to Vivian Moutinho (left) of UFRJ, Brazil and Lindokuhle Diadla (right) of Torrecid South Africa.
CITIC Heavy Industries, formerly known as Luoyang Mining Machinery, was one of the national key construction projects of China's First Five-Year Plan. The company has experienced significant changes and improvements over the past 60 years and has grown into both a national and international innovative and high-tech enterprise, a global large-sized backbone enterprise which has one of the largest manufacturing facilities for heavy-duty equipment that supports both projects in China and overseas. CITIC HIC has been involved with three previous MEI comminution conferences, in 2014, 2016 and 2018 but only once before, at Comminution '16, as a sponsor, so we are pleased to welcome them to Comminution '25 represented by Will Yuan Xinchao and Yuanzheng Hao of China and Sam Hearn, of South Africa, seen talking below to Michael Antwi, of Gold Fields Tarkwa Mine, Ghana.
I think everyone in the mining industry is now well aware of how important sensor-based electronic sorting has become and we are pleased to have the continuing involvement of Steinert, one of the leaders in this field. Steinert sponsored two of last year's 4 MEI conferences, Physical Separation '24 and Critical Minerals '24. so it is not surprising that they are a sponsor of Comminution '25, as sorting waste rock and ore with low concentrations prior to comminution saves energy and water and enriches the grade of the ore. Steinert's ‘dual energy’ x-ray transmission (XRT) is ideally suited for ore sorting because the x-ray radiation can penetrate stones with particle sizes up to 100 mm, allowing metals to be detected, even when they are not on the surface. In addition to XRT, Steinert offers other sensors that can be combined with one another. XRF (x-ray fluorescence) can be used to determine and sort individual chemical elements very precisely and optical sorting and lasers are well suited to the detection of ores with different colours, or crystalline structures.

The representatives from Steinert, Germany, John Knouwds, Lutke Von Ketelhodt and Jean Makola |
Boaz Friedland is Technical Director at Energy and Densification Systems. South African company EDS was formed in 2005 and their Multishaft Mill is designed and produced in South Africa. The milling action combines a number of processes to provide an output product to match various specifications. These processes are crushing, milling, densifying, blending and attrition. He is seen below talking to Sherry Bremner, of the University of Cape Town.
Gebr. Pfeiffer is a family-run business with its head office in Kaiserslautern, Germany, The company has pioneered the development of modern grinding, separating, drying, slaking, and calcining technologies for more than 150 years. Christian Altherr and Caroline Woywadt, of Gebr. Pfeiffer are seen below talking to James Pownell, of FLS, Australia.
Growth Steel was established in 1989 to manufacture wear parts for grinding mills. The company's headquarters are in North Sumatra, Indonesia but they have additional sales offices located strategically around the world. in Perth, Brisbane, South Africa, Ghana, Peru, Chile and China. This is their first time at an MEI Conference, and good to see five representatives.
Another great day of presentations ended with a welcome second sundowner in the Vineyard gardens.
The Cape Point Vineyards, stunningly situated above Noordhoek beach, was our venue after the sundowner, thanks to our sponsor Russell Mineral Equipment, who had kindly invited the MEI team to join their customers and agents at a fine VIP dinner.
