Recently, a large-scale centralized grain storage project equipped with six sets of bolted galvanized steel silos has been successfully installed and put into trial operation in the grain processing base, marking a new upgrade in automated bulk grain receiving, storage and discharging capacity for the enterprise.
Project Core Technical Parameters
Silo Quantity & Layout Total 6 vertical circular cone-bottom steel silos, arranged in two groups of three silos side by side, compact and standardized layout, matched with overhead horizontal conveying truss and central vertical bucket elevator to form a fully enclosed automatic grain circulation system.
Single Silo Specification
Effective Volume per silo: 1200 cubic meters
Rated Storage Capacity: 960 tons per unit (calculated by grain bulk density 800kg/m³)
Total project storage capacity: 5760 tons for six silos combined
Overall height of single silo: 24.6 meters
Silo inner diameter: 8.2 meters
Hopper inclination angle: 45°, ensuring complete gravity self-flow discharge without grain residue inside the bin
Material & Anti-Corrosion Standard
Main plate material: Q235B carbon steel corrugated galvanized sheet
Wall plate thickness: 3.0mm for upper silo body, 3.5mm for lower pressure-bearing section
Cone hopper plate thickness: 4.0mm reinforced thickened plate
Surface treatment: Full hot-dip galvanizing with 275g/m² zinc coating, strong anti-rust, anti-oxidation and anti-corrosion performance, adapting to long-term outdoor open-air service
Supporting structure: All load-bearing legs, bracing frames and ladder platforms adopt hot-galvanized angle steel and square tubes, with stable mechanical structure and strong wind and load resistance.
Complete Automated Conveying System As shown in the aerial photo, the project is equipped with:
Top overhead closed belt conveyor running through all six silos, realizing automatic grain distribution to each bin
Central vertical bucket elevator for grain lifting, cleaning and circular turnover
Integrated maintenance walkways, safety guardrails, inspection ladders and operation platforms on the top truss, convenient for daily inspection, ventilation detection and equipment maintenance
Independent discharge gate at the bottom of each cone hopper, connected with underground conveying pipelines for automatic outbound transportation.
Project Highlights & Application Value
1. High Standard Food-Grade Storage, Effectively Guarantee Grain Quality
The fully sealed silo structure can be equipped with optional temperature and humidity monitoring, ventilation dehumidification and insect repellent systems, effectively avoid grain mildew, caking, pest infestation and bird and mouse damage during long-term storage, greatly reduce post-harvest grain loss.
2. Highly Automated, Greatly Reduce Labor Cost
From grain incoming lifting, automatic bin allocation, static storage to quantitative automatic discharging, the whole process realizes mechanized and intelligent operation, only requiring a small number of operators for centralized control, solving the pain points of high manual handling cost and low efficiency in traditional warehouse storage.
3. Modular Bolted Structure, Stable and Long Service Life
The silo adopts international standard bolt assembly technology, no on-site welding, short construction cycle, convenient transportation and installation. The overall designed service life reaches more than 20 years, with low later maintenance cost and high comprehensive economic benefit.
4. Wide Adaptability for Multiple Granular Materials
Apart from conventional wheat, corn, rice, sorghum and other food grains, this set of silo system can also be applied to the storage of soybean, feed pellets, coffee beans, oilseeds and other bulk granular raw materials, with strong scalability for subsequent production line upgrading.
Industry Significance
The completion and commissioning of the six-unit large steel silo storage project sets a benchmark for standardized and intelligent bulk grain storage in the regional agricultural processing industry. It helps the food processing enterprise realize large-scale raw material reserve, stabilize raw material supply chain, improve production efficiency and product quality control level, and also provides a mature replicable overall solution for similar grain depot, feed mill and agricultural deep-processing industrial park storage projects.
