en.Wedoany.com Reported - Minera Chinalco Perú completed the full disassembly of a single 22 MW (28' × 44') ball mill rotor in seven days, setting a new benchmark for large-scale maintenance operations in the global mining industry. This technically challenging operation, considered highly complex in the sector, involved the controlled removal of reusable components such as end covers, seals, magnetic poles, and rotor covers, preserving the mechanical integrity of each part while preparing for subsequent reinstallation in the project.

This operation marks the first major milestone of the company's ongoing mill replacement project, carried out while the concentrator plant was in operation. This required precise coordination between maintenance tasks and the continuity of production operations. According to the company, the main challenges were ensuring personnel safety, maintaining plant operational stability, and executing a large-scale intervention without affecting process performance.

To achieve this goal, Minera Chinalco Perú employed specific engineering, planning, and construction methods, integrating new workflows, technical solutions designed for the project, and continuous coordination among engineering, operations, and execution teams. These strategies significantly reduced intervention time without compromising work quality or the integrity of components to be reinstalled in the next phase of the project.

With this achievement, Minera Chinalco Perú has set a new global record for such operations, highlighting the importance of innovation, planning, and technical management in the maintenance of strategic assets. This record contributes to improving the availability and reliability of critical mining equipment.
