Weartech SHS Overlay Wear Plate Exceeds Wear Life of 500 Brinell Q&T Plate by 400%
PROBLEM: SEVERE SLIDING ABRASION
At an underground molybdenum mine in Colorado, a small fleet of 90 ton side dump haulpak 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 in. (13 mm) Brinell 500 wear plate. Severe sliding abrasion results in the Brinell 500 wear plates requiring replacement every 6 months.
SOLUTION: WEARTECH SHS 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 Weartech SHS9700U overlay wear plates, which feature higher resistance to severe sliding abrasion and longer service life.
Weartech SHS9700U has demonstrated a 4x improvement over Brinell 500 wear plate
Weartech SHS9700U overlay wear plate, 1/4 in. (6 mm) overlay on 1/4 in. (6 mm) substrate
Weartech wear plates remain in service
after hauling over 3 million tons in 28 months
RESULT: WEARTECH SHS EXCEEDS 500 BRINELL WEAR LIFE BY MORE THAN 4X
The Weartech SHS9700U overlay wear plates remain in service after hauling more than 3 million tons in 28 months while 500 Brinell plates are replaced at an average rate of every 6 months.
Benefits to the mine include elimination of:
• 3 pairs of replacement wear plates
• Manpower hours during 3 replacement cycles
• Truck service time
• Production output and revenue
