Steel silo engineering 4*1000T for barley and oat

Features of storage silo (spiral steel silo):

1. High strength: The grain storage silo wall is reinforced by vertical stiffener and occluded by screw beam. It has great strength and good resistance to wind, earthquake and snow.

2.Good sealing function: Crimping and seaming of five-layer spiral steel plates ensures airproof, so our grain storage silo can be used to store construction materials such as cement, gypsum, fly ash and slag, as well as liquids.

3.Small area occupancy: The smallest distance between grain storage silo amounts to 600mm.

4.Short construction cycle: High-level automatic construction at site, Need only 5-6 days for a 1,000 tons storage silo.

5.Long working life: 25-30 years, achieved by best combination of plates of different thickness for grain storage silo body.

Main Process of Steel Silo Engineering

  • Raw Material Receiving Section: Feeding by truck discharge, manual dumping, or railway etc.

  • The Cleaning System: drum cleaner machine or vibrating cleaner machine, for removing impurites from the grains, like stone, straw, etc. 

  • The Drying System: decrease the extra moisture of grain.

  • The Storage System (Ventilation System, Level System, Temperature Monitoring System)

----- Flat Bottom Steel Silo

Generally, this type of silos are with large capacity, its concrete base civil works will be manufactured by clients, and we will provide drawings to client for construction.

-----Hopper Bottom Steel Silo

Generally this type of silo are with small and medium capacity.

Type A: With Steel Structure & Steel Cone (Not more than 1500 tons per unit silo)


Type B: With Concrete Structure & Concrete Cone (≥1500 tons per unit silo)



  • The Discharging System

Discharge with conveyor machine, connected with bagging system, or truck loading system, or other processing line after the silos

  • The Control System
