what is a Finished Product Silo？

The finished product silo is a caching storage equipment used at the back end of the production line to store processed qualified finished particles/powders. It is a standard configuration for organic fertilizer, compound fertilizer, and granulation production lines, connecting granulation, screening, and packaging sections.

Core function of finished product silo

1. Buffer and voltage stabilization: The production line continuously discharges materials and intermittently operates packaging. The finished product warehouse is used to store materials to avoid the whole line shutdown caused by packaging not keeping up
2. Homogenization and homogenization: Different batches of finished products are mixed in the warehouse to ensure uniform nutrition and particle size, reduce color difference, and grade separation
3. Sealed temporary storage: isolate moisture and prevent organic fertilizer from rebounding and clumping; Supporting dust removal and controlling dust
4. Stable feeding: Uniform feeding at the bottom, quantitative feeding to the packaging machine, stable packaging speed

Structure composition of finished product silo (commonly used for organic fertilizers)

Warehouse body: mainly made of carbon steel, with wear-resistant, anti sticking and anti-corrosion inner walls; High humidity materials can be selected from 304 stainless steel
Cone bucket: The cone angle is designed according to the material’s angle of repose, and organic fertilizer particles are generally ≥ 60 ° to ensure self flow
Arch breaking device (key): pneumatic vibrator, air cannon, spiral arch breaking, solving organic fertilizer bridging and material blockage
Detection: High and low level gauges (anti rotation/radar), automatic stop of loading when full, and empty material alarm
Discharge components: star shaped unloader, gate valve, screw/belt conveyor
Optional: Warehouse top dust collector, breathable cap, observation port, insulation layer, multiple outlet material separation

Classification of finished product silos

Vertical square silo: commonly used in organic fertilizer production lines, with small footprint, low cost, and multiple outlets
Vertical circular steel plate silo: large capacity, better sealing, suitable for large composite fertilizers, sand and gravel, cement lines
Thermal insulation finished product warehouse: asphalt mixture, high requirement particles, reducing temperature drop

Key points for selecting organic fertilizer finished product warehouses

1. Capacity: Allocated according to production capacity, generally caching 1-4 hours of output
2. Priority for blockage prevention: Organic fertilizer has strong moisture absorption and must be equipped with a broken arch. It is easy to build bridges with only a cone bucket
3. Anti segregation: Feed diversion structure to avoid stratification of large particles and fine powders
4. Discharge: Prioritize variable frequency star shaped discharge or discharge from the bottom of the belt, with controllable flow rate
