Strudex Rubber Mill Liners – Extending Wear Life and Delivering Customer Satisfaction in Mineral Processing Plants

[Hengshui / 2nd March, 2026] 

Application Scenario

A typical mineral processing plant operates a SAG mill (diameter 10.4 m, length 5.6 m) in a high‑throughput grinding circuit. The mill processes highly abrasive ore with lump sizes up to 200 mm. Liner replacement is a critical operational factor directly affecting mill availability and production cost.

The Challenge

In many mineral processing plants, conventional rubber mill liners often suffer from uneven wear – feed‑end liners and discharge components wear significantly faster than the rest of the mill. This creates “weak links” that can force premature shutdowns. Additionally, as liners wear, the internal mill volume increases, causing throughput to rise and energy consumption per ton to fall, which requires constant recalibration of load cells to avoid inefficiency or overloading. Plants need a liner solution that delivers consistent, predictable performance and extends the time between maintenance stops.

The Strudex Solution

Strudex’s engineers apply advanced material science and application‑specific design. After analysing the plant’s mill dynamics, wear patterns and ore characteristics, we provide a tailored package:

1. Superior rubber compound – A high‑tensile, wear‑resistant Strudex blend formulated specifically for abrasive ores, offering exceptional wear resistance while retaining elasticity to absorb grinding energy.

2. Customised liner profiles – Enhanced tapering in high‑impact areas (feed end and lifter bars) optimises slurry flow and energy absorption. Critical discharge components are redesigned to match the extended life of main shell liners.

3. Precision moulding – All liners are precision‑moulded to exact mill specifications, ensuring uniform thickness and consistent performance across the entire set.

Customer Feedback at 7 Months

Seven months after installation, the customer reported strong positive feedback and full satisfaction. The Strudex rubber mill liners have been operating continuously without any failure or unexpected behaviour. The plant confirmed that the liners still showed sufficient remaining life, demonstrating that Strudex delivers beyond typical expectations. Based on the wear condition observed in the field, the customer now expects the mill liners to achieve a total service life of 18–24 months.

Key Advantages of Strudex Rubber Mill Liners

Strudex liners are designed based on decades of experience, optimising grinding performance while improving mill uptime. Their lightweight nature makes handling safe and easy, significantly reducing the risk of injury during installation and replacement. Easy installation and replacement further minimise maintenance duration. The result is increased uptime and optimised throughput – the mill runs longer and more efficiently between stops.

Longer wear life also brings improved sustainability. High‑performing parts improve overall grinding efficiency, and long‑lasting liners mean fewer parts are needed over time. This reduces material consumption and waste. Additionally, fewer maintenance stops mean less time spent in hazardous areas, directly improving worker safety.

The mill lining protects the equipment and has a large impact on mill performance. Grinding is a tough process, especially when processing abrasive ores, and the liner plays a crucial role. Strudex rubber mill liners give you longer wear life with extra value: increased sustainability, lower maintenance, improved safety, increased production through optimised throughput, and increased uptime. Longer wear life is especially important when you have other wear parts that need to match the same service life – Strudex helps you align replacement schedules and avoid unnecessary shutdowns.

Conclusion

Seven months after installation, Strudex rubber mill liners have proven their value with genuine customer satisfaction. By combining material science, customised design, and a clear focus on operational benefits – safety, uptime, throughput, sustainability – Strudex delivers a reliable, long‑lasting solution for mineral processing plants facing abrasive ore conditions.
