Our grain storage silos, equipped with pre-cleaning systems, are engineered for long-term durability and excellent weather resistance. They are ideal for the bulk storage of maize (corn), wheat, paddy rice, and other grains. Constructed from hot-dip galvanized steel, each silo is designed for a service life of 30 to 50 years, ensuring safe, hygienic, and reliable storage performance.
The integrated pre-cleaning system efficiently removes dust, straw, and other impurities before grain enters the silo, improving storage conditions and protecting grain quality
Application Scope
Maize and wheat flour milling plants
Paddy rice processing lines
Animal feed mills and livestock farms
Grain collection and trading depots
Soybean and oilseed handling facilities
Breweries and malt processing units
Available in flat-bottom or hopper-bottom types, these silos come in capacities from 50 tons to 10,000 tons and can be fully customized to meet your specific storage and discharge requirements.
