The non-homogenising Portal Scraper store, is normally used in a production line as a bulk material buffer store. The store operates with stockpiles placed in line. While building up one pile by Cone Shell stacking another pile is being reclaimed. The stacker and the portal scraper travel on separate rails along the store. The portal scraper consists of a portal frame with a scraper chain system. The material is reclaimed by the scraper chain system and in a constant flow transportsed onto an outgoing rubber belt conveyor.
