Classification of steel silo
Steel silo are mainly used for storing corn, wheat, sorghum, soybeans, rice, milled rice, soybean meal, etc. Based on different construction methods, steel silos can be classified into spiral steel silo, bolted assembly steel silos, and welded silos, each with its own characteristics.
Spiral steel silos have a short construction period and low cost, but their storage capacity is limited, and they cannot be disassembled. Bolted assembly steel silos feature a high degree of standardization and can be prefabricated; they are simple to assemble, highly mobile, have a long service life, offer a wide range of storage capacities, and are cost-effective.
Advantages of welded silo
welded silo exhibit excellent airtightness, have thick steel plates, high strength, allow for high grain storage heights, possess good corrosion resistance, and have a long service life. Therefore, in coastal ports, where steel is susceptible to salt corrosion, welded silos are often used.
Due to their high airtightness requirements, welded silos are frequently employed. The use of steel silos also necessitates the integration of corresponding systems and processes, such as grain intake and outtake, ventilation, fumigation, grain condition monitoring, cleaning, dust removal, loading and unloading, storage, cooling, and explosion prevention, which provide safeguards for the safe storage of grain in steel silos.
What is a Spiral steel silo
Spiral steel silo, as the name suggests, are formed by biting and rolling steel plates using a spiral silo rolling machine. This advanced silo rolling machine mainly consists of key components such as a decoiler, edge roller, forming machine, triangular gin pole, and electrical control system. Currently, spiral silo rolling machines are mainly available in two specifications: SM30 and SM40. Among them, the SM30 model is suitable for silos with diameters ranging from 3 to 8 meters, while the SM40 model can meet the construction needs of silos with diameters ranging from 6 to 18 meters.
Characteristics of Spiral-rolled flat-plate steel silo
Spiral-rolled flat-plate steel silos boast numerous remarkable characteristics. Their overall structural performance is outstanding, and they have a long service life. During the construction process, they rely entirely on specialized equipment for construction, ensuring that every detail meets high standards.
During the rolling process, the outer wall of the silo is carefully bitten into a spiral bead with a width five times the material thickness (30mm – 40mm) and tightly welded to the silo body. This unique design significantly enhances the load-bearing capacity of the silo. Therefore, in terms of overall strength, stability, and seismic performance, spiral silos (often referred to as Lipp silos) outperform other types of silos.
Wide application of silo
In addition, spiral steel silo are made of materials with excellent corrosion resistance, which enables them to perform well in resisting erosion from harsh environments, thereby further extending their service life. Meanwhile, their airtightness performance is also exceptional, enabling them to meet the storage needs of various materials.
Whether it’s sand and gravel aggregates or grain and other powdery or granular raw materials, spiral silos can ensure the quality of any part of the silo body through their exquisite craftsmanship, achieving good sealing effects. For grain storage, they can even meet special process requirements such as pest control and fumigation. Moreover, based on the different properties and process requirements of solid and liquid materials stored, spiral steel silos have been widely used in various fields, including agriculture.
