Introduction The circular stockyard top stack side-pickup stacker reclaimer is a new type of indoor storage equipment developed on the basis of the increasing environmental protection requirements and land saving requirements. This Bulk Stacker Reclaimer is arranged in a closed factory building, which solves the problems of material loss and scattering during the stacking process and due to the influence of wind and rain. By setting up peripheral retaining walls, the problem of storing more materials in a smaller space is solved. This Circular Stacker Reclaimer equipment adopts the conical shell stacking process and the side scraper partitioned and layered retrieval process for stacking operations. It is currently widely used in various raw material stockyards that do not have high requirements for homogenization. Principle Both the stacker and the reclaimer can rotate around the center column. The stacker rotates to the pre-stacked silo area and sta…
