The bridge reclaimer, in conjunction with the proper stacking method, offers the very high blending ratio often required for homogenizing limestone, coal, iron ore, and other materials. Spans the pile and supports a trolley that reciprocates its travels gradually along the length of the box girder. In the picture, the bridge type box girder Suspended from the trolley are triangular harrows (or "rakes"), one per side, loosening the material on the pile cross-section. Each harrow is adjusted to a slanted position, matching the angle of repose of the stacked material. As the bridge reclaimer inches towards the pile, the harrow loosens the material so that it runs under gravity to the foot of the pile. There, a scraper chain collects the material and transports it to the yard conveyor. The reclaimed capacity is controlled by varying the travel speed of the machine.
In rectangular storage yard, there are two stock piles along the length direction. The reclaimer shall be in the middle of the two stock piles when working, and adjust the claw to a certain angle via the luffing support according to the material repose angle. When reclaiming, adjust the traveling speed of the big cart according to the reclaiming requirements. Along with stretching and withdrawing of the hydraulic cylinder, the claw takes down the upper materials from the stock pile, and allows it to slide down to the bottom of the stock pile and be carried away by the continuously operating scraper. The material will finally be scraped into the discharging belt conveyor under the end discharge channel to be transported out.
After picking a pile of material, start the big cart traveling motor to move the reclaimer to another section of the stock pile to start reclaiming again
