HEAVY ENGINEERING & WEAR PARTS designed by the Sweden-based company .
Recognising that limitations in testing of sheeting makes it difficult for engineers to rank , specify and select premium natural rubber compounds , Trelleborg developed SETAT™ – Submerged Elevated Temperature Abrasion Test .
This advanced , rigorous test and performance ranking tool demonstrated that GoldLine Premium 38 offered significantly lower rubber loss than alternative products , maximising sheeting life and , thereby , lowering total cost of ownership for mine operators .
Keith Jones , Business Development Manager for the product , said : “ In a two-year development program to perfect the sheet rubber ’ s formulation , extensive in-house SETAT verified the product outranks alternatives in terms of rubber loss .”
Jones said the sheeting , with its distinctive gold colour , represents a significant milestone for Trelleborg in the premium natural abrasion sheet rubber market .
“ A dedicated and collaborative product development effort across multiple Trelleborg operations has culminated in an offering that will help mining and mineral processing operations across Australia manage wear caused by abrasive process slurries ,” he said .
The sheeting is easily applied to steel surfaces using Trelleborg ’ s contact adhesives . It also has excellent workability and flexibility , in particular when applied under tension and compression , the company said . Custommanufactured roll widths and lengths additionally minimise yield loss or offcuts when lining equipment and pipe spools .
Comprehensive mill relining
“ Replacing steel lining systems inside the confined space of grinding mills is a timeconsuming and demanding job , requiring strict safety measures and highly reliable equipment ,” Jared Le Cras , Director , Mill Reline Equipment at Metso Outotec , says .
The OEM has recently extended its mill reline equipment offering with a high-capacity Mill

Reline Machine ( MRM ) to aid the process .
The new robust MRM has a capacity of 4,000 kg , enabling easy and safe replacement of steel lining systems inside even the largest grinding mills , according to the company .
“ With the addition of the high-capacity MRM , Metso Outotec now provides a comprehensive range of MRMs designed to ISO and IEC standards ,” Le Cras said . “ The new MRM is designed for heavy-duty lining replacement tasks , with safety and efficiency as our top priorities .”
Benefits of the Metso Outotec MRM include efficient mill relining enabled by unique mechanical design features ; maximised reliability , thanks to easy data access and wears and spares replacement ; minimised risk , thanks to important safety features ; and comprehensive service support via Metso Outotec ’ s global service network .
In addition to MRMs , Metso Outotec ’ s mill reline equipment offering includes feed chute transporters , Tube MRMs and bolt hammers . IM
