Lime steel silo is one of the most commonly used methods for the storage of lime. Lime is rigid inorganic gelled material and calcium oxide is its main ingredient. Flyer adopts advanced Germany silo construction technology, and the building technology is unique. When constructing, first feed the 495 mm wide coil sheet by a decoiling machine into a bending machine. Through bending, seaming, and then through the forming machine rolling into needed geometric shape, around the silo lateral forming a 30-40 mm wide, encircling spiral protruding strip on the structure playing the role of strengthening silo. For two different kinds of materials, silo construction equipment also can realize double bending processing. Spiral steel silos are on site operation and the silo top is ground installation. Flyer lime steel silo is also spiral designed without any spike or screw, the steel plate margin is totally seamed by seaming machine. It brings much convenience to the construction process and saves labors.
