Truck Side Door Wear Life Increased By 400%

NanoSteel eliminates three pairs of replacement wear plates and increases truck service time

Problem: Severe Sliding Abrasion

At an underground molybdenum mine in Colorado, a small fleet of 90 ton side dump haul trucks transport ore from loading chutes to a primary crusher.

When a truck dumps ore at the crusher, the entire load slides over a pair of lower side doors, each lined with a 1/2” (13 mm) Brinell 500 wear plate. Severe sliding abrasion results in the Brinell 500 wear plates requiring replacement every 6 months.

 

    Solution: NanoSteel Overlay Wear Plate

    To reduce the number of replacement cycles for side door wear plates, in December 2008 the mine replaced a pair of Brinell 500 wear plates on one truck with NanoSteel SHS 9700 overlay wear plates which feature higher resistance to severe sliding abrasion and longer service life.

      Result: NanoSteel Exceeds Brinell 500 Wear Life by 400%

      NanoSteel SHS 9700 overlay wear plates remain in service after hauling more than 3 million tons in 28 months while Brinell 500 plates are replaced at an average rate of every 6 months. Benefits to the mine include elimination of three pairs of replacement wear plates and manpower hours during 3 replacement cycles, with increases in truck service time, production output and revenue.
