The present invention relates to a raw material discharging facility (RECLAIMER) for discharging and transporting raw materials, that is, ores, piled into a yard of a steel mill, and more specifically, a belt in a tripper part of a conveying conveyor passing through a lower part of a raw material discharging facility. To support the conveying conveyor for discharging raw materials as another sub-conveyor without using the impact controller to prevent the impact controller, which is installed to support the lifted state, from being easily damaged by the impact exerted by the weight of the conveyed material. A tripper double conveyor of a raw material dispensing system.

In general, raw materials such as ores used in steel mills are unloaded from nearby docks and loaded into a yard adjacent to the factory via a transport conveyor. Raw materials stored in these yards are piled up and piled up. That is, it is dispensed by the branding facility and the reclaimer and is put into operation.

However, when the raw material is transported using such a conveyor belt, the material is collided when the material is transported according to the equipment condition. For example, the impact of the raw material falling due to the distance between the belt and the chute is intensified to the belt and the roller. Alternatively, the impact trolley at the initial entry position among the rollers installed in the TRIPPER PARTDP, in which the belt to which a heavy weight transport material such as ore is transported, is raised. During the collision, the impact of the belt, as well as the early wear of the roller is easily generated, and in severe cases, belt meandering is caused by roller wear, and the roller itself is broken.
