Storage Silo

What is a Storage Silo?

A storage silo is an auxiliary device designed for temporary storage and buffering of bulk materials, commonly used in powder and granule production lines. It is usually made of carbon steel or stainless steel, providing stable storage, controlled discharging, and seamless connection to the next process.

Role of a Silo in the Production Line

In a typical production process:

Grinding → Mixing → Elevating → Silo → Elevating → Packaging.

The silo serves as a buffering station by:

• Receiving materials after grinding or mixing;
• Providing short-term storage and transition;
• Ensuring controlled discharging to the next elevating or packaging step.

Key Functions of a Silo

1. Material buffering: Prevent interruptions or blockages between upstream and downstream processes.
2. Uniform feeding: Ensure steady discharging via screw, vibrating, or pneumatic valves.
3. Batch management: Allow transition between batches while keeping production continuous.
4. Reduced manual handling: Improve automation and reduce labor intensity.

Common Types and Configurations

• Materials: Carbon steel, SS304, SS316L.
• Structures: Square silo, conical-bottom silo.
• Discharging types: Screw conveyor, pneumatic gate, vibrating discharger.

Industry Applications

• Food processing: Flour, starch, seasoning storage.
• Spices & herbs: Buffering after grinding.
• Chemicals: Powder and granular raw material transition.
• Agriculture & feed: Storage of feed pellets and additives.
• Building materials: Buffering of mortar, putty powder, dry mix.

ထုတ်ကုန်အားသာချက်များ

• Robust structure with customizable capacity.
• Seamless integration with production lines.
• High hygiene standards for food and pharma.
• Smooth discharging, preventing bridging or clogging.
• Optional integration with automation systems.

Conclusion

As an auxiliary device in production lines, a silo not only provides buffering and transition but also enhances continuity and automation. It has become an essential part of powder and granule processing systems.
