-Full name: Yibao Cement Depot/IBAU Silo (German IBAU Technology)
-Application: storage+homogenization+unloading of cement, clinker, raw meal, fly ash and other powdery/granular materials
-Features: large diameter, large capacity, center pressure reducing cone, multipoint unloading, high homogenizing efficiency
2、 Typical structure (core)
Reservoir body: 15 – 22 m in diameter, 30 – 50 m in height, reinforced concrete cylinder, slip-form construction.
Pressure reducing cone (core): large concrete cone is set at the bottom of the reservoir to reduce the pressure of materials on the bottom of the reservoir and form the central flow+annular flow to ensure homogenization.
Unloading system: multiple unloading ports+air chutes/plenum boxes are arranged at the conical bottom or in the annular direction to realize uniform, continuous and low-energy unloading.
Foundation: Annular or plate foundation, applicable to large load and foundation settlement.
3、 Main advantages
-Large reserves: the capacity of a single reservoir can reach 10000-50000t, occupying less land.
-Good homogenizing effect: the fluctuation of material composition can be controlled within ± 1% to stabilize cement quality.
-Smooth unloading: not easy to block and arch, low power consumption (about 0.1 – 0.3 kWh/t).
-Strong durability: reinforced concrete structure, 30-50 years of service life, easy maintenance.
4、 Application Scenario
-Cement plant: finished cement warehouse, clinker warehouse and raw material warehouse.
-Mixing station/grinding station: fly ash, mineral powder and cement storage.
-Chemical plant/power plant: powdery materials, dry ash storage.
5、 Difference from common silo
-Ordinary warehouse: flat bottom or shallow cone, easy to block materials, poor homogenization and difficult to discharge materials.
-Yibao Reservoir: Deep decompression cone+multi-point gas-filled unloading, good homogenization, smooth unloading and large reserves.
