At present, the diameter of the coiled spiral steel silo can be selected between 3 and 25m, the height-to-diameter ratio (the height of the straight cylinder divided by the diameter) can reach up to 5.75, the height of the straight cylinder can reach up to 31.5m, and the maximum capacity of a single warehouse can reach 6500t .Manufacturing and installation process: transport the silo manufacturing equipment (coil bin unit) to the construction site, and follow the procedures of uncoiling, entrance, forming, undercut, push, and rise for galvanized coils, continuous bending, and bite The finished silo. During construction, the 495mm wide coil is sent from the uncoiler to the forming machine to be rolled into the required geometric shape, and then bent by the undercutting machine, bitten (5 layers of spiral hemming), around Along the side of the silo, a 30-4mm wide continuous spiral encircling convex rib is formed.
