552 To stabilize the operation, three secondary crushing lines were integrated using station and conveyor products. The objective was to reduce the granulometry from 430 mm to 150 mm and neutralize the lamellarity of the ore. Under a fast-track methodology, the project was completed in ten months, including 8.5 months of fabrication, assembly and commissioning in space-constrained areas, ensuring the suitability of the material before its transfer to the long-distance conveyor belt. 2.

SCOPE This research analyzes the S11D Project under the pillars of Innovation, Circularity, and Recovery through modular stations. In Innovation, modular architecture and parallel manufacturing reduced assembly by 28%. In Circularity, the use of skid-type bases AISC-2016 replaced civil infrastructure, allowing asset relocation. In Recovery, the 9.5 km LDC was stabilized, reaching 2,200 t/h through granulometric control (150 mm) and lamellarity reduction. The study validates mobile structures to optimize the life cycle and operational continuity in large-scale mining. 4. STATE OF THE ART In contrast to traditional crushing station solutions, which are based on structures designed under project-specific and rigid criteria, this proposal is founded on an integral modularization concept. Under this approach, the station is configured through a set of pre-designed modules selected to be efficiently integrated, ensuring compliance with the defined capacity requirements. A representative example of the application of this model is the pebble crushing station at the Mina Justa mining unit, where component standardization optimized the response to site operational demands. 5. IMPROVEMENT Concrete foundations limit flexibility and prolong schedules in large-scale mining, restricting asset mobility against risks such as damage from lamellar morphology. The transition toward modular infrastructures without permanent civil bases is fundamental for accelerated deployment. These relocatable solutions optimize the capital life cycle and mitigate environmental liabilities, allowing the full recovery and reuse of components throughout the various phases of the mine.
