DynaPrime for Australia’s SAG and large ball mills: wear-life and downtime notes for plant teams
Reviewed by Joe Ashwell

First reported on Australian Mining
30 Second Briefing
Tega Industries’ DynaPrime mill liner system targets large Australian SAG, AG and primary ball mills, where unplanned downtime can cost operators millions in lost production. The design combines customised composite lifter profiles with high-wear rubber or hybrid liners, engineered to suit specific mill diameters and charge trajectories rather than relying on standard liner geometries. For plant metallurgists and maintenance teams, the key promise is longer wear life and faster relines, directly affecting mill availability and throughput on constrained grinding circuits.
Technical Brief
- System is supplied in large, modular liner segments to minimise the number of pieces per reline.
- Lifter and plate packages are engineered using site-specific charge trajectory and impact modelling, not catalogue layouts.
- Tega Losugen supports designs with on-site wear monitoring and iterative liner profile adjustments between campaigns.
- Composite constructions allow different rubber or hybrid materials in high-impact vs high-abrasion zones within one panel.
- Fastening patterns are customised to existing shell drilling, avoiding re-drilling or shell modifications on brownfield mills.
- Design intent is to maintain consistent mill power draw and volumetric filling as liners wear, stabilising grind performance.
- For similar large-mill upgrades, such custom liner packages can defer capital expansion by debottlenecking grinding capacity.
Our Take
The focus on SAG and large ball mill uptime in Australia aligns with other Australian Mining pieces on MASPRO and AMS, where supply-chain delays and structural integrity issues are also framed as multi-million-dollar downtime risks for fixed plant.
With lost production in mills described in the millions, DynaPrime-type solutions are likely to be evaluated alongside other high-impact productivity technologies in our database, such as Decoda’s real-time haul road hazard detection, as part of integrated reliability programmes on large open-pit sites.
