Project Challenges
1,000 t/day of continuous milling: raw material must come in, stay in and move out on demand
When the dedicated rail siding delivers a concentrated batch, wheat must be received and allocated to silos quickly; when the mill is consuming, grain must be discharged fast to the blending plan. Capacity and in/out rates must match both “concentrated arrival” and “continuous consumption.”
Large silos for volume, small silos for flexibility — one silo type is not enough
Bulk wheat needs large-capacity silos for long-term storage at lower unit cost, but blending, conditioning and multi-variety turnover need small silos for fast switching. All large silos make small batches inflexible; all small silos make bulk storage expensive. The silo mix must follow the mill’s actual blending process.
Central Asian continental climate demands in-silo temperature control
Uzbekistan has cold winters, hot dry summers and large day–night temperature swings. After filling, wheat is prone to condensation and localized heating, and ordinary storage leads to quality loss that directly affects raw material stability for milling. The silos need aeration and temperature control to prevent quality decline in storage.
Storage must connect seamlessly with rail logistics and the flour lines
The silos are not stand-alone equipment: upstream they connect to the dedicated rail siding and grain logistics project, downstream to the cleaning and milling workshops. Conveying, dust control and storage scheduling must match the plant process — no “silos built, but logistics cannot connect.”
03 / Solution
Solution: 1,000T × 6 + 200T × 5 Spiral Silo Combination
1,000T × 6 groups (large silos)
Handle bulk receiving from concentrated rail arrivals and long-term storage. Large single-silo capacity and low unit storage cost suit bulk storage of the main wheat varieties.
200T × 5 groups (small silos)
Support blending, conditioning and flexible turnover of small batches. Small capacity and fast switching suit segregated management of different wheat qualities and recipe-based discharge.
Spiral silo construction
Spiral-lock forming gives good structural integrity and airtightness, and on-site forming is fast — matching the project’s requirements for construction schedule and sealed storage.

04 / Highlights
Technical Highlights: Why Spiral Silos + a Large/Small Silo Combination
Spiral silos: well sealed and fast to build, suited to bulk grain storage
Spiral-lock forming gives the silo body better structural integrity and airtightness than conventional assembled construction, supporting aeration control and moisture-proof and insect-proof storage. On-site rolling shortens the construction cycle, allowing the silos to advance in parallel with the logistics project and line construction. For Central Asia’s continental temperature swings, sealed silo bodies with aeration and temperature control reduce condensation and localized heating risk.
Large + small silos: bulk efficiency and recipe flexibility together
Six 1,000T large silos solve “store more at lower cost”; five 200T small silos solve “switch fast and blend accurately.” This is not simply stacking capacity — it is designed around the mill’s actual process of “bulk storage + multi-variety blending,” avoiding the turnover bottleneck a single silo type would create.
Integrated with rail logistics and the production line
The silo group layout connects with the dedicated rail siding and grain logistics project. Inlet and outlet capacity is configured for both concentrated arrival and continuous production, and storage scheduling matches the flour line’s consumption rhythm.

✓
As part of the group’s storage system, the project supports its business covering general-purpose and specialty flours for the domestic market and neighbouring Central Asian countries.
06 / Testimonial
Client Feedback
“What satisfies us most about this project is not how fast the silos went up, but how well the silo combination matches our blending process. The 1,000 t silos take rail deliveries, the 200 t silos handle blending turnover, and inlet/outlet and the logistics line connect smoothly. Since commissioning, raw material receiving and discharge scheduling have never suffered waiting or overstocking caused by an unsuitable capacity structure.”
