Integrated Solutions: Our materials technology

Jul 22, 2020
Our advanced materials technology is at the heart of the Weir Minerals integrated solutions philosophy: delivering superior quality equipment that lasts longer and helps our customers achieve a lower total cost of ownership.
 
With centres of technology innovation across the world, our materials science team is ideally placed to closely coordinate with our manufacturing, product development and sales teams to develop new materials that offer our customers better performance.
 
The needs of our customers are the primary driver of our materials development, and we continually enhance our product line to combat problematic issues and challenging applications identified in the field.
 
Materials technology is an inherently iterative field, based on combining close understanding of on-site conditions and careful testing and field trial processes to ensure that expectations are borne out in practical applications.
 
Development teams work diligently to ensure a new material is wear-tested in multiple locations to ascertain how it performs in different applications and environmental conditions. Wear testing typically involves 3D scanning and forensic analysis of observed wear profiles to determine wear rates and characteristics at pre-determined milestones. The feedback gained from such trials is invaluable, not only in assessing and reporting performance, but also for material design.
 
Our international team
 
An example of great international collaboration can be seen in a project last year in Canada’s Oil Sands region, where together with a customer, the local Weir Minerals team identified the need to develop an entirely new slurry pump volute liner in a short time span.
 
This program required close and effective collaboration between the Canadian team, Weir Minerals’ pump technology team in Madison, Wisconsin, our Todmorden foundry in the U.K. and a materials development team based in Sydney, Australia.
 
The team quickly realised that in order to execute on the new, thicker design, a brand-new alloy would be required for casting, which thanks to the outstanding, rapid information sharing between Todmorden, Madison and Sydney, was completed in record time.
 
Our constantly improving materials
 
While materials development is often a slow but continual process of iteration and small improvements, the team has achieved some breakthrough results in recent years, such as the launch of the A68 alloy as well as the R67 and R508 elastomers, all of which offer as much as a 30% wear life improvement over existing materials in demanding applications.
 
New areas of focus for the team are additive manufacturing and composite materials, which can be used for particularly severe applications as either a primary wear material, or as an insert inside a more economical alloy or elastomer, to increase the reliability of equipment and prevent unplanned shutdowns.
 
These developments are the result of close consultation between the materials science team and manufacturing, generating products such as Linard® modular abrasion panels with chromium white iron inserts, and trials involving the application of tungsten carbide coatings and inserts on pumps in highly abrasive situations.
 
To maintain the team’s innovative edge, Weir Minerals has formed close partnerships with leading universities to provide practical experience to some of the world’s most promising engineering, metallurgy and chemistry students. These interns are not only a fantastic source of new ideas for the team, but many have continued their work with Weir Minerals following graduation.
 
Our materials technology is fundamental to continuing to deliver market leading products to our customers, and one of the four cornerstones to our Integrated Solutions approach.
