ME Digital Lab

ME Elecmetal combines technology and innovation to serve the global mining industry with integral solutions to optimize processes.

Proven durability: No insert detachment. No fractures. No compromises.

Faced with a customer challenge of stabilizing operations at a concentrator plant with a 40×29-foot SAG mill and two 27×49-foot ball mills, ME Elecmetal collaborated with site personnel to conduct a validation test of the new ME PolyLight liner configuration. Initially, the SAG mill was fitted with 30 cast SMX discharge lifters. While the SMX liners met durability and performance expectations, ME Elecmetal sought an innovative solution to better absorb drastic operational fluctuations.

The proposed solution was the ME PolyLight design — a hybrid concept combining a robust cast lifter with a ME PolyFIT™ plate.

ME PolyLight™ combines a high-strength cast lifter with a resilient ME PolyFIT® plate, delivering the perfect balance of toughness, flexibility, and sustainability. It’s the best of both worlds — cast durability and rubber flexibility — engineered to perform under pressure.

Key Benefits:

Lower Effective Cost:

By extending liner life and improving operational stability, the ME PolyLight design drives down the overall cost of production.

Recyclability:

Both cast components and ME PolyFIT™ materials are incorporated into ME Elecmetal’s circularity initiatives, ensuring environmental responsibility.

Reliability:

Engineered to absorb operational variability, the hybrid design leverages the toughness of cast lifters and the resilience of ME PolyFIT® to protect critical high-impact areas.

Implementation:


To tackle the unstable operational challenges, ME Elecmetal replaced the SMX lifters with the ME PolyLight solution. Featuring a plate with rolled steel inserts paired with a cast lifter section, the design provided enhanced impact resistance while maintaining the original mill volume — avoiding the need for thicker, heavier liners.

Test Campaign Highlights:

  • Processed 16.89 million tons over 199 days.
  • Wear patterns were consistent with historical trends.
  • Initial assessment based on grates installed on 08-23-2023.

 

Results:

  • Achieved a 17% reduction in wear rates.
  • No insert detachment or fractures were observed in cast elements.
  • Successfully absorbed operational variability without compromising liner integrity or requiring unplanned maintenance.
  • Demonstrated that enhanced durability can be achieved without reducing internal mill volume.

The ME PolyLight solution validated ME Elecmetal’s innovative approach to liner design — delivering superior reliability, operational flexibility, and sustainability benefits while driving down maintenance costs and downtime.
