The Environmental-friendly Circular Stockyard System is used for the stockpiling of large-scale bulk materials. The stock bin adopts the circular cement retaining wall, with the upper steel structure net rack dome as the enclosure. The boom stacker and the luffing scraper reclaimer centering around the central pillar are set up inside the stock bin. The materials are transported to the boom stacker through the belt conveyor on top of the dome for the rotary stockpiling, thus forming the circular stockpile. The scraper reclaimer scrapes the materials layer by layer from the inner side of the stockpile and conveys these to the chute below the central pillar. Then the materials are exported through the feeder. It has such features as a high level of automation, stable and reliable operations, small size, non-pollution and no damage to materials.
