In what it says is a major milestone, Russell Mineral Equipment (RME) has designed and completed production of its 500th Mill Relining Machine (MRM) for Australia-based gold producer Northern Star Resources Ltd.

This custom-made RUSSELL MRM will be accepted by Northern Star at a ceremony at RME’s global headquarters in Toowoomba, Queensland, this month. This MRM will service Northern Star’s new SAG mill at its Thunderbox project in the Goldfields of Western Australia.

RME and Northern Star began their relationship at the Kanowna Belle Operations, some 30 years ago with the purchase of RUSSELL MRM number five (MRM005). Northern Star owns six RUSSELL MRMs, including the 400th RUSSELL MRM, commissioned in 2018 at Kanowna Belle. Thismachine replaced a RUSSELL MRM that had been in operation at Kanowna Belle for 25 years.

The 500th RUSSELL MRM is a RUSSELL 7-axis, 6,000-kg capacity machine. The RUSSELL 7 is RME’s signature model sold globally, and this unit also comes with advanced RME INSIDEOUT™ technologies. These proprietary new technologies, developed by RME, enable placement and removal of grinding mill liners without any crew working on the charge inside the mill, greatly reducing exposure of personnel to significant hazards, the company says.

Since the introduction of the very first RUSSELL 7-axis MRM in 1992, traditional mill relining times have been quartered and many health and safety hazards have been eliminated, RME says.
Chief Customer Officer, Cherylyn Russell, says RME is a proud supplier to the hard-rock mining and mineral processing industry, primarily those processing gold and copper.

“This milestone is a chance to acknowledge the technology and safety advances of the RME Mill Relining System that enable giant grinding mills to get back to work quicker after regular relining,” she said. “Mill relining is the most specialised maintenance task in the mineral concentrator process and often dictates the length of shutdowns. RME’s innovative, customised, robust equipment helps increase mine site profitability, all while improving the safety of the working environment.”
