Tega DynaMax mill liners: uptime and wear-life insights for plant engineers
Reviewed by Tom Sullivan
First reported on Australian Mining
30 Second Briefing
Tega is promoting its DynaMax liner range as a full-coverage solution for mill grinding circuits, with the DynaPrime variant engineered specifically for large 28‑ft and above SAG and ball mills. The system focuses on optimising liner profile and wear life to extend mill uptime, stabilise power draw and improve grinding efficiency, particularly in high-throughput operations. For plant and maintenance engineers, the key implication is potential reductions in unplanned relines and more predictable mill availability across both primary SAG and secondary ball mill duties.
Technical Brief
- DynaMax liner family is configured to cover the full mill grinding circuit, not single-mill retrofits.
- DynaPrime variant is explicitly targeted at very large SAG and ball mills from 28 ft diameter upwards.
- Design intent is to provide a single liner supplier across primary SAG and secondary ball mill duties.
- Common liner philosophy across mills simplifies spares inventory, change-out tooling and relining crew training.
- Unified liner geometry across the circuit can support more consistent charge motion modelling and power-draw prediction.
- Standardised liner interfaces reduce reline duration risk when swapping between SAG and ball mill maintenance windows.
Our Take
Within our 853 Mining stories, only a small subset of Product-tagged pieces focus on mill liners for large SAG and ball mills, so Tega’s DynaPrime targeting 28 ft units sits in a relatively specialised niche of plant optimisation coverage.
For Australian operations, liner systems at the 28 ft scale are typically a bottleneck for both planned and unplanned downtime, so any demonstrable reduction in change-out time or liner wear would have outsized impact on unit costs at large gold and base-metal concentrators.
Given that many brownfield Australian mills are constrained by footprint rather than power supply, products like Tega’s that aim to improve volumetric efficiency and liner life at existing diameters are likely to be evaluated as an alternative to expensive mill upsizing projects.
