Up to 20X the Life! SA6000 Patented Complex Carbide Overlay Plate EX5500 Clam Liner Case History

A large hard rock gold mine installed a SA6000® Patented Complex Carbide Plate Liner on their EX5500 Clam. It was recently inspected after running for a total of 8,230 service life hours over a duration of 18 months. The SA6000® surface shows such little wear that the weld seams have not even been worn away!

For comparison, our SA1750CR® Chromium Carbide liners last between 10 and 11 months. We estimate the SA6000® will provide up to 20X the life at the current wear life!

Service Life at Inspection (Months): 18

Service Life at Inspection (Hours): 8,230

Average Thickness Loss at Inspection (Inches): 0.0136”

Modernizing Power:
How SAS Slashed Downtime and Saved Millions with MPS89 Modernization

When a 700MW B&W wall-fired unit needed an overhaul on its seven MPS89 mills, SAS Global stepped in with a complete modernization strategy that delivered speed, savings, and performance.

The SAS Edge:

• 33% Faster Overhauls: SAS cut overhaul time from 15 days to just 10 per mill.
• Smart Spending: Instead of blindly replacing ring seats, SAS inspected, retained good components, and reinvested savings into high-impact upgrades.
• Key Upgrades Included:
• Patented Closed Race Rotating Vane Wheel with Cast Deflector Liners
• SA2000 Classifier Cone & Extension Kit
• High-Spin Static Classifier & Multi-Outlet Diffuser
• Mill Wall Liners, Tire Shields & More
  
  

What Changed?

• Shorter outages and lower maintenance costs
• Boosted combustion stability and mill performance
• Operators noticed the difference—and requested repeat work
• After full implementation and boiler tuning: measurable heat rate improvement
  
  

The Bottom Line: Just a 5% heat rate gain at this 700MW plant (fuel @ $2.50/MMBtu, 85% capacity factor) equates to:

• 2.6 million MMBtu in fuel savings annually
• $6.5 million/year in reduced fuel costs
• <2-year payback on modernization investment
  
  

Conclusion:
SAS Global’s mill modernization program isn’t just faster—it’s smarter. This project proved that targeted upgrades and performance-minded decisions deliver serious ROI.

Mining Truck Bed Tail Section Liner Still Going Strong After 10 Years in Service

CAT 793D Series SAS Global Premium Truck Bed Liner

A large hard rock gold mining facility recently performed a scheduled inspection and maintenance on one of their CAT 793D haul trucks. This bed was removed from service due to the alloy steel ahead of the SA1750CR Premium Chromium Carbide Overlay Plate tail section needing to be replaced. This truck had been utilizing the same SAS Premium Liner System for 10 years!

During this maintenance, the SAS Global SA1750CR Tail Section Liner only had a few hot spots. These simply required hand overlay via hardface welding, which was done in the field. The back 90" SA1750CR liner was then released back into production for a second time.

The thickness inspection revealed the SA1750CR Tail Section only lost 0.187” (just about half the starting thickness), and the wall liners only show very slight signs of wear after 65,000 hours of service over the last 10 years!

Apron Feeder Chute Liners Still Going Strong After 5 Years in Service

Fabricated from SureAlloy® SA1750CR® Premium Chromium Carbide Overlay Plate

A large hard rock gold mining facility installed SA1750CR Premium Chromium Carbide Overlay Plate apron feeder liners into their transfer chute system in 2015. Material from the pit is dumped directly into this system from the haul trucks. These liners were just inspected in August of 2020 and all appear to still be in good shape. These SA1750CR Liners have been in service for 5 years and are still going strong!
