What are the discharging methods of steel silo?

 



Steel silos have various discharging methods depending on factors like silo diameter and desired efficiency. Here are some common methods:

Full cone bottom self-gravity discharging: Material smoothly discharges due to gravity with minimal residual material. However, it requires a high cone bottom design, increasing foundation height and cost, making it less suitable for large silos.

Half cone bottom combined with silo backfilling discharging: Similar to above but with a lower foundation. It requires some backfilling, reducing usable silo capacity, and is limited to small/medium diameter silos.

Flat bottom multi-point discharging: Material relies on additional methods (sweepers, loaders) for discharge as it cannot self-empty entirely. This method utilizes all silo space but requires extra equipment and potentially larger openings for equipment access.

Multi-point discharging combined with silo backfilling: This combines features of above methods. It uses multiple discharge holes for better self-emptying while minimizing backfill amount. It's suitable when sweepers or loaders are unavailable but can be complex to construct.

Other methods: Less common methods include sidewall discharging and vibration discharging for materials with poor flowability.
