We have installed two 50-meter radial stackers at the Zierbena Adosado dock in Santurce.
The basic function of all radial stackers is to place a pile of bulk material, in this case limestone sand, stored at a uniform height and width. This is accomplished when the stacker moves in a slow turning motion (horizontally from side to side) making a curve as the material flows.
This system consists of a chain feeder for receiving product directly from the truck, with a belt width of 2,200 mm, which discharges into the stacker via a conveyor belt to improve the transition of material between the two.
Each stacker is 50 meters long with an inspection and maintenance walkway on both sides. In addition, it includes a misting system to minimize environmental impact during operations.
Each stacker has an output of 600 tn/h with a density of 1.6 T/m3, and can store up to 60,000 tons of material between them at a stacking height of 16 meters.
