Scraper stacker and reclaimer is a continuous and efficient bulk material handling machinery widely applied in coal mines, ports, electric power plants, metallurgy, cement, and coal chemical industries. This machine is characterized by its excellent environmental protection performance, high storage capacity, high blending homogenization ratio, and the ability to perform simultaneous stacking and reclaiming operations. HDM can independently design and manufacture various types of scraper stacker and reclaimers, including circular-yard scraper stackers and reclaimers with reclaiming capacities of 100 to 5000 t/h, stacking capacities of 100 to 6500 t/h, and yard diameters of 60 to 120 m; 100 to 5000 t/h gantry or semi-gantry scraper reclaimers; and 100 to 1000 t/h bridge-type scraper reclaimers.
