Industrial Wear Problem
Skip cars are used in underground mining for transporting ore in process from one station to the next. During loading and unloading, wear plate inside the cars are exposed to sliding abrasion and impact.
In an underground gold mine in Canada, 20 ton capacity skip cars transport ore between two levels. During loading, ore drops 30 feet (9 meters) onto a wear plate deflector and slides into the car. During unloading, the skip car is tilted at a 30 degree angle on one side and the ore slides over the wear plate deflector onto a belt conveyor for transport to the next station.
Solution: NanoSteel Overlay Wear Plate
To increase the life of the skip car deflector and reduce surface material loss, the mine installed a NanoSteel SHS 9800 overlay wear plate, 1/2 inch thickness (3/16 inch overlay on 5/16 inch substrate), for resisting sliding abrasion and impact. |

Result: NanoSteel Exceeds Life of Q&T Plate by 2.9x and CrC Plate by 2x
The NanoSteel SHS 9800 overlay wear plate was removed from service for maintenance after deflecting more than 1 million tons of ore. This represents a service life increase of 2.9x over 500 Brinell quench & temper (Q&T) monolithic wear plate, 5/8 inch thickness, and up to 2x over chrome carbide (CrC) overlay wear plate, 5/8 inch thickness (5/16 inch overlay on 5/16 inch substrate). Upon being placed back in service, mine engineers are predicting the NanoSteel SHS 9800 plate will exceed Q&T plate life by 4.3x before requiring replacement. |
