Portal Scraper Reclaimer
A portal scraper reclaimer in an indoor installation, features two reclaimer booms with a pair of traversing scraper chains and scraper flights. This arrangement is used to avoid interference with the roof structure.
In case of an outdoor installation, a single reclaimer boom can be used.
To reclaim the stacked material, the reclaimer booms are lowered until the scraper flights engage in the material while the portal reclaimer moves along the pile. The scraped material is loaded onto a yard conveyor alongside the pile.
The reclaimed capacity is controlled by varying the travel speed of the machine.
