Description Benefits Features Operation

ME PolyFIT® Rubber Mill Liners

At ME Elecmetal, we understand that every mill is different. That’s why our industry-leading ME PolyFIT® rubber mill liners are custom-designed and precision-engineered to match your mill’s unique geometry, operating conditions, and performance goals. Whether you’re managing mill power constraints, trunnion bearing loads, weight limits, or grinding media volume, our tailored solutions are built to maximize grind recovery and optimize overall mill performance.

Each ME PolyFIT® rubber mill liner is crafted with your mill’s specific needs in mind—ensuring maximum volume utilization and operating efficiency. By aligning our designs with your exact parameters, we help boost both your mill’s productivity and profitability.

Engineered for Fit, Flexibility, and Reliability
Our rubber mill liners are available in a variety of high-performance rubber compounds, engineered to meet the toughest operational demands. With a balanced design that targets high- and low-wear zones, ME PolyFIT® liners extend wear life, reduce replacement cycles, and minimize maintenance downtime—lowering your overall operating costs. In field trials, ME PolyFIT® has delivered wear life improvements of over 11%, driving significant cost savings.

Lighter Weight. Greater Efficiency.
Weighing 35–40% less than traditional steel liners, ME PolyFIT® rubber mill  liners are safer and easier to handle, reducing installation risks and improving worker safety. Lighter liners also increase mill chamber capacity—boosting throughput without compromising structural integrity. Each liner is delivered with precision components, certified lifting points, and on-time logistics support, ensuring a smooth, efficient installation process.

Proven Results. Trusted Partnership.
Backed by decades of global milling expertise, ME PolyFIT® rubber liners help our customers achieve:

  • Increased throughput

  • Improved mill availability

  • Extended operating cycles

From the first consultation through ongoing aftermarket support, ME Elecmetal is your partner for continuous improvement, responsive service, and performance optimization throughout your liner’s lifecycle.

Features

  • Standards-Compliant Materials: ME PolyFIT® liners are manufactured with rubbers that meet ASTM D standards across multiple classifications, ensuring consistent performance and reliability.

  • Customized Designs: Every liner is engineered to match your mill’s specific requirements, delivering tailored solutions that optimize grinding efficiency and equipment life.

  • High-Performance Rubber Compounds: High-pressure molded rubber compounds deliver exceptional abrasion resistance and maintain their design profile significantly longer than conventional materials. This results in better mill sealing, minimized slurry leakage and erosion, and more efficient power conversion for optimal particle size reduction.

  • Lightweight and Easy to Install: Our rubber and composite liners weigh 35–40% less than steel alternatives, making them safer and easier to handle. The reduced weight speeds up reline times, decreases installation risks, and increases overall mill uptime.

  • Increased Chamber Capacity: Lighter liner systems allow for greater mill chamber volume, enabling higher throughput without sacrificing structural integrity or operational safety.

 

Operation

Our ME PolyFIT® rubber mill liners are engineered for a wide range of grinding processes, providing reliable performance in:

  • Primary, Secondary, and Tertiary Ball Mills

  • Regrind Mills

  • AG and SAG Mills

  • Flue Gas Desulfurization (FGD) Mills

  • Scrubber Mills

  • Lime Mills

Versatile and Adaptable Solutions
ME PolyFIT® rubber liners are designed to fit nearly every position in SAG mills (excluding discharge grates) and all components of ball mills. They are especially effective in demanding applications where:

  • Equipment faces high-impact conditions.

  • Liner weight must be minimized to reduce structural strain.

  • Redesign is needed to reduce the number of components and simplify assembly.

  • External bolting of liners is required for easier and safer installation.
