:: Chile’s MIRS Launches World First EMMR Robotic Mill Lining Innovation


MIRS has launched an innovative robotic solution to automate the process of changing wear liners in mills without any human intervention. The company said a unique team had responded to one of the greatest technological challenges of the mining industry, by executing the change of liners “at a speed never before achieved, with high standards of quality, efficiency and safety.”

MIRS launched the revolutionary robotic solution, fully developed in Chile, for the lining of SAG and ball mills, at an international event that took place on September 5 at the industrial testing facilities owned by the company, a subsidiary of the HighService Corp company, in San Bernardo.

Major players in the mining sector, led by the Minister of Mining, Baldo Prokurica, and more than 40 executives from mining and engineering companies in Chile and Peru, had the opportunity to witness a full-scale model of a 36 in SAG mill , and the operation of the EMMR (External Mill Maintenance Robot), the world’s first fully automated system that performs this operation autonomously and without human intervention.

“The launch confirms not only the progress and the high level of technological development achieved by MIRS worldwide, but also represents the greatest advance of recent times in automation for the process of changing mill liners in the mining industry, in safety and quality terms.”

“Mining is challenged to change the way we extract and produce metals and minerals. It is now when the industry has the possibility to transform its processes and resume its productivity and competitiveness indices, and that is why the incorporation of technologies and innovations are totally necessary to face it, in a process where robotics plays a very important role,” the President and CEO of HighService Corp, Hugo Salamanca, told the audience.

The process of changing coatings is a task that, in the case of SAG mills, must be carried out every three or six months and, in the case of ball mills, every 8 to 18 months, depending on the hardness of the minerals being milled. Until now, the only way to execute it was through manual work, performed by a team inside and outside the mill with the support of manual hydraulic machines, in a high-risk environment that is the main cause of the mill’s lack of availability of a concentrator plant. “Minimising the time to execute the lining of the mill is a condition that the industry has always demanded,” says Igor Elías, Manager of the Commercial Area of MIRS Mill Reline. “This innovation in plant maintenance reduces maintenance times and increases worker safety,” he adds.
