The Coalition for Energy Efficient Comminution (CEEC)

The Coalition for Energy Efficient Comminution (CEEC) is a global initiative and independent not-for-profit corporation, providing access on the most current technical scientific papers and field studies to the worldwide mining industry. CEEC’s vision is to accelerate the implementation of eco-efficient comminution practices through promotion of supporting data and industry benefits. CEEC was established by a visionary group of mining industry leaders, who recognized the need to provide a platform for effective communication of the latest technical findings on efficient comminution practices. CEEC is led by a board of directors, and enjoys the patronage of industry luminaries from reputable mining associations and global companies like Rio Tinto.

CEEC’s mission is supported also by the Australian Federal Government Energy Efficiency Opportunities program which encourages large energy-using businesses to improve their energy efficiency. It does this by requiring businesses to identify, evaluate and report publicly on cost effective energy savings opportunities.

After a long process of analysis and evaluation (more than a year), CEEC has approved and published in August 2018 in its category for Energy Efficient Innovations the Official Report of the industrial tests of grinding bodies RELO (Model M1.1) in Europe (Bulgaria - Rudozem) “Industrial Tests with Innovative Energy Saving Grinding Bodies”, thus confirming the energy-efficient advantage of our innovative product:

MEI's Comminution conferences are established as the main events for profiling cutting-edge research and innovation in all aspects of crushing, grinding and ultrafine grinding in the minerals industry. MEI presents industrially based research papers showing the benefits of basing practical application on scientific rigour, such as the industrial validation of models and control techniques.

The report Rethinking Grinding Efficiency in Ball Mills by Dr R. Chandramohan, N. Kolev, Dr N. Weerasekara, G. Lane, presented at Comminution 2021, provides insights on the opportunity that RELO media in combination with optimized liner design can increase the grinding efficiency in ball mills by 10% for equivalent ball media volume. The report includes insightful lab test-data by RELO, and expertise in DEM simulations and analysis by Weir Minerals, a global company creating innovative engineering solutions for the minerals, oil & gas, power and industrial markets. The report was presented at Comminution 2021 also thanks to Ausenco, a global company providing consulting, engineering, project delivery and asset operations, management and optimisation solutions to the minerals & metals, oil & gas and industrial sectors.
