How are composite materials redefining wear plate maintenance?
In mining and bulk material handling, wear is a direct production risk. Transfer points, crusher discharge zones and chutes are exposed to continuous abrasion and heavy impacts, leading to downtime, safety risks and significant financial losses when failures occur.
Traditional hardened steel has long been the standard, but in high-impact and high-abrasion environments it reaches its limits. Frequent replacement increases maintenance intervals, safety risks and overall operational costs.
Wear plates must resist both sliding abrasion and heavy impact. However, increasing hardness improves wear resistance while reducing toughness, making materials more brittle. This trade-off limits the performance of single-material solutions such as hardened steel.
Composite materials combine different properties in one structure. ROXDUR wear plates use:
-
Cemented carbide for extreme hardness and abrasion resistance
-
Iron matrix for toughness and impact resistance
This combination allows the plate to withstand both impact and abrasion simultaneously.
Although composite wear plates have a higher initial cost, they significantly reduce maintenance frequency, downtime and labor. With up to 10–15 times longer service life, they improve overall return on investment and operational continuity.
They also enhance safety by reducing the need for maintenance in hazardous areas and contribute to sustainability through longer usage and reduced material consumption.
They provide the highest value in applications with both impact and abrasion, such as:
-
Crusher discharge zones
-
Transfer chutes
-
Mining operations
-
Bulk handling ports
-
Steel plant material handling
How are composite wear plates different from steel?
They combine hardness and toughness, while steel requires a compromise between the two.
Are they suitable for high-impact applications?
Yes. The iron matrix absorbs impact energy while carbide resists abrasion.
Can they be customized?
Yes, designs can be adapted to match specific dimensions and operational needs.
