The car dumper is the first equipment to perform work in the iron ore export production process. Its function is to remove the iron ore from each train wagon, which transports it directly from the mines to the harbor. Within the engineering system has a standardization of how the car dumper is divided. The systems of this machine are the pusher car, which has a mechanical arm that positions the wagon to be dumped; the train locker; the rotation device is mainly composed by rotational rings and clamps, that make the wagon tip; the feeder, where the ore falls and is directed to the conveyor belt. The wear plates are assembled in the hoppers at a height of 1117 mm below the car dumper in 47 positions. These plates experience impact and abrasion wear in a location difficult to be reached. To reduce maintenance a material with higher impact resistance and a good abrasion resistance was developed in laboratory and later tested in the hopper, the performance is evaluated against the original plate. Both laboratory tests and field tests confirmed the superior wear and impact resistance of a eutectic alloy for application in this car dumper.
