The 300 Ton Conical Bottom Steel Silo

The 300 ton conical bottom steel silo is a large-scale core equipment for storing large quantities of bulk materials, specializing in large-scale closed and fresh-keeping storage of grain, feed raw materials, and industrial granular powders. Adopting a 45 ° standard cone bottom design, material self discharge is achieved with zero residue and no blockage. The warehouse body is made of high zinc coated anti-corrosion steel plate, which is tightly sealed and has stable load-bearing capacity. It is equipped with standardized safety accessories, and the on-site modular assembly is convenient, with strong durability and easy operation and maintenance. It can efficiently meet the needs of large-scale storage, batch transfer, long-term reserve and other essential scenarios.

Product Advantage

1. Modular precision manufacturing and installation: Corrugated sheets are processed by automated cold rolling, punching, and bending production lines, with high dimensional accuracy; Modular assembly of the entire machine on-site, compact footprint, short construction period, supports parallel expansion of multiple warehouses, and is suitable for large-scale site layout.

2. Extra large load-bearing+safety reinforcement design: External thickened M-shaped galvanized columns are used to strengthen the load-bearing capacity, and key load-bearing parts are specially reinforced. The structure is stable under a full load of 300 tons, and safety accessories such as warehouse doors and straight ladders are standard. Daily inspections and material control are safe and convenient.

Product Uses

1. Large grain depots/grain storage centers: Suitable for cross season storage of wheat, corn, and rice in national grain depots and regional storage bases, with a large capacity of 300 tons to meet bulk storage needs. The 45 ° cone bottom is combined with mechanized unloading, greatly improving grain turnover efficiency and reducing storage losses by sealing and moisture-proof.

2. Large scale feed processing group: As a centralized transfer warehouse for core raw materials such as soybean meal, corn, and bran in large-scale feed factories, it reduces the frequency of feeding with large capacity, and the high anti-corrosion board is resistant to raw material corrosion. The self discharge seamlessly connects with the automated production line to ensure the continuity of large-scale production.
