The 500 Ton Conical Bottom Steel Silo

The 500 ton conical bottom steel silo is a large-scale storage equipment designed for bulk materials, specializing in the large-scale closed storage of grain, feed raw materials, and industrial granular powders. Adopting a 45 ° standard cone bottom design, material self discharge, zero residue and no blockage are achieved. The warehouse body is customized with high zinc layer anti-corrosion steel plate, which is tightly sealed, has strong load-bearing capacity, and is equipped with standardized safety accessories. The on-site modular assembly is convenient, durable, and has low operation and maintenance costs, which can meet the core needs of large-scale base bulk storage, long-term reserve, and transit turnover.

Product Advantage

1. 45 ° Cone Bottom Self Flow Unloading (Zero Residue Core Technology): Adopting a standardized 45 ° cone bottom inclination structure, it completely solves the problems of material bridging, blockage, and residue at the bottom of the warehouse. The unloading efficiency is 90% higher than that of a flat bottomed warehouse, and it is suitable for tightly sealed storage of various types of bulk materials such as grain, granular materials, and industrial powders, without the need for manual clearance throughout the entire process.

2. High anti-corrosion sheet+ultra long service life: Selected from Handan Iron and Steel double-sided 275g/㎡ high zinc layer zinc aluminum magnesium sheet, the corrosion resistance of the warehouse roof is 5 times that of ordinary galvanized sheet, and the warehouse body is resistant to deformation and weathering. Paired with 8.8-10.9 level national standard high-strength bolts, the design service life is up to 30 years, and the full cycle operation and maintenance cost is extremely low.

Product Uses

1. Large grain depots and regional storage bases: Suitable for cross season storage of wheat, corn, and rice in national grain depots and local grain distribution centers, with a large capacity of 500 tons to meet the needs of large-scale storage. The 45 ° cone bottom is matched with mechanized operations, with efficient unloading without residue, sealed and moisture-proof, greatly reducing grain mold and loss.

2. Centralized storage of raw materials for large feed groups: As a transit storage warehouse for core raw materials such as soybean meal, corn, and bran for leading feed enterprises, it has a large capacity to reduce frequent feeding costs. The high anti-corrosion board is resistant to raw material corrosion, and the self discharge seamlessly connects with automated production lines to ensure uninterrupted large-scale production.
