Wear plates fight wear and extend the life of components in cement plants, power plants, and a variety of other industries. In the following sections, we will discuss a case study related to the use of overlay wear plates in the mining industry.
Problem
At an underground molybdenum mine in Colorado, several 90 ton side dump haulpak trucks transport ore from loading chutes to a primary crusher. The truck dumps the ore into the crusher and the complete load slides over a pair of lower slide doors, each of which is lined with a 13 mm Brinell 500 wear plate. This results in severe sliding abrasion, which makes it mandatory that the Brinell 50 wear plates are replaced every six months.
NanoSteel Overlay Wear Plate Features
In order to ensure that the side door wear plates are not replaced frequently, the mine substituted a pair of Brinell 500 wear plates on one truck with NanoSteel SHS 9700 overlay wear plates that have higher resistance to sliding abrasion and a longer service life.

Advantages of the NanoSteel SHS 9700
The replacement of the Brinell 500 wear plates with the NanoSteel SHS 9700 overlay plates benefited the mine in the following ways:
- Elimination of three pairs of replacement wear plates
- Elimination of manpower hours during three replacement cycles
- Increase in service time of the truck
- Increase in production output and revenue

NanoSteel SHS 9700 has demonstrated a 4x improvement over Brinell 500 wear plate
Conclusion
The NanoSteel SHS 9700 overlay wear plates continue to serve after hauling over 3 million tones in 28 months whereas Brinell plates were replaced every 6 months.
