Storage Grain Silo Roll Forming Machines

Storage grain silo roll forming machines are essential equipment for the agricultural and bulk material handling industries. This guide provides a comprehensive overview of grain storage silo roll formers, including types, characteristics, applications, specifications, suppliers, installation, operation, maintenance, and more.

Overview of Storage Grain Silo Roll Forming Machines

Storage grain silo roll forming machines create corrugated metal silos for storing bulk materials like grains, animal feeds, fertilizers, etc. The roll forming process transforms flat metal sheets into cylindrical or conical silo panels.

Key benefits of using grain storage silo roll formers:

  • Highly customizable design – diameter, height, slope, panel shape can be adjusted
  • Fast production of silo components
  • Consistent quality and dimensional accuracy
  • Cost-effective automated process
  • Durable all-weather construction
  • Quick and easy assembly on site

Roll formed silos are widely used for grain handling on farms, in bulk terminals, and food/feed processing plants. Their modular design allows creating small or mega-ton capacity silos as per storage needs.

How to Install and Operate

Proper installation and operation ensures optimum performance and longevity of storage grain silo roll forming machines.

Installation Tips

  • Mount machine on flat, level concrete base
  • Align to sheet coil feed line
  • Anchor securely to floor
  • Connect electric power supply
  • Install safety guards and controls
  • Test run without load

Operation Guidelines

  • Adjust roller gap as per sheet thickness
  • Set speed in correlation with sheet feed
  • Use edge guides to center sheets
  • Set forming angles to achieve desired corrugation
  • Ensure lubrication and cooling systems work
  • Inspect rollers and guides periodically
  • Clean collected metal debris frequently
  • Follow preventive maintenance schedule

Take supplier assistance for initial installations. Train workers thoroughly on procedures.

Maintenance and Precautions

Regular maintenance is vital for storage grain silo roll formers to deliver high production yields and avoid breakdowns.

Maintenance Activities

Inspect rollers and guidesDaily
Check electrical wiringWeekly
Lubricate roller bearingsMonthly
Adjust drive chain tensionQuarterly
Clean or replace air filters6 months
Inspect and realign rollersAnnually

Safety Measures

  • Ensure proper machine grounding
  • Keep emergency stops accessible
  • Wear protective eye glasses and gloves
  • Avoid loose clothing or jewelry
  • Manage and segregate metal scrap
  • Follow lockout procedures before maintenance

Troubleshooting Tips

  • Uneven sheet feeding – realign edge guides
  • Sheet jamming – check roller gap, reduce speed
  • Excessive noise – lubricate bearings and joints
  • Blurry corrugations – replace worn out rollers
  • Power fluctuations – install voltage regulator

Proactive care combined with preventive maintenance enhances the performance and lifespan of grain storage silo roll forming machines considerably.

Pros and Cons of Roll Formed Silos


  • Lower material cost vs welded silos
  • Uniform quality and dimensional accuracy
  • Higher corrosion resistance
  • Faster assembly with bolted construction
  • Lower maintenance requirement
  • Modular expandable design
  • Customizable height and diameter


  • Not suitable for small capacities below 2000 tons
  • Limited number of unload-fill cycles
  • Not fully airtight like welded silos
  • Penetration by rodents needs prevention
  • Monitoring systems require separate installation

For grain storage above 5000 tons and 20-30 year lifespan, roll formed silos present a cost-effective solution.

Storage grain silo roll forming machines enable efficient production of corrugated metal silo panels customized for diverse agricultural bulk storage needs.

With appropriate machine selection, installation, operation and maintenance, substantial benefits in silo construction speed, cost optimization, weather protection, and durable long-term storage can be realized.

Careful comparison of specifications and reputation of leading roll former manufacturers is advised to get the best value equipment. With some design limitations, roll formed silos present a worthwhile investment for most grain handling operations compared to conventional welded silos.


Q: What metals can be used to make grain silos via roll forming?

A: Galvanized steel and aluminum sheets are commonly used. Steel offers strength while aluminum provides weather resistance. Required sheet thickness is 0.5-1mm.

Q: What factors affect the load bearing capacity and strength of roll formed silos?

A: Rib patterns, sheet thickness, steel grade, corrugation profiles, and bolt connections determine the load capacity. Radial rib silos offer the highest strength.

Q: How long does it take to install a roll formed grain silo on site?

A: A typical 50 feet diameter, 45 feet tall silo would require 3-4 days for roll forming the panels and 3 days for installation by a trained crew.

Q: What is the expected lifespan of roll formed grain silos?

A: With proper maintenance and upkeep, roll formed silos will easily last 20-30 years. The galvanized coating provides long-term corrosion protection.

Q: How to decide on the diameter for grain silos?

A: Diameter choice depends on storage capacity needed, available space, filling/unloading rates required, land constraints, and discharge cone dimensions. Typical range is 20 to 60 feet.

Q: What are some key accessories needed for grain storage silos?

A: Essential accessories include temperature cables, grain spreaders, access ladders, safety cages, inspection doors, unload equipment, aeration fans and ducting.

Q: Is on-site operator training provided for grain silo roll forming machines?

A: Reputed suppliers offer 2-3 days of on-site training to customers for proper machine operation, maintenance and troubleshooting.

Q: How much space is needed to install a storage grain silo roll forming machine?

A: Approximately 1200 square feet of floor space is required for a standard roll former with some additional space for raw sheet coils.
