CIRCULAR STEEL SILO
(CHROME)

Modular-construction industrial storage and mass-management station

Round-section, modular-bodied industrial storage systems for storing — to high hygiene standards — flour, semolina, bran and waste materials in either in-process or finished-product form in flour, semolina, feed and pulse mills. Custom-designed for the physical position of the use location, the logistic role in the plant diagram and the flowability character of the material to be stored, these silos safeguard the plant’s raw-material supply security and stock-management stability.

WORKING PRINCIPLE

Bolted manufacture and acoustic round geometry — modular rigid body structure: the silo bodies are built by joining high-strength steel plates with a modular bolted-assembly design; the round chassis geometry spreads the internal mass pressure evenly over the walls, maximising static-load stability. Food-regulation inner epoxy and oven-baked outer powder coating — sophisticated surface-coating technology: to preserve the chemical structure of the stored food materials, the silo’s inner surfaces are coated with an epoxy paint fully compliant with international food regulations, while the outer surfaces are protected against harsh environmental conditions and corrosion with oven-baked powder-coating technology. Heavy-duty anchored steel-construction legs — rigid base and foundation integration: to safely bear the high-volume bulk loads, the silo base is rigidly mounted on heavy-duty steel-construction legs using strong industrial anchor systems.

KEY ADVANTAGES

- Very wide application range and sectoral flexibility: For the specific needs of flour and semolina mills, each of the products — finished flour, semolina, bran and process waste — is designed at geometric angles suited to its bulk density and friction coefficient.

- “Food-grade” inner surface and maximum sanitation: The special food-grade epoxy coating on the inner walls reliably prevents flour or semolina from sticking to the metal and forming microbiological layers (bacteria, mould) in the pores; it provides a smooth flow surface.

- Easy logistics via modular bolted design: Making the silo panels modular and bolted allows fast, weld-free assembly even in tight plant spaces; minimising transport volume, it offers a logistics-cost advantage.

- Superior wall protection via oven-baked powder coating: The industrial electrostatic oven-baked powder coating applied to the silo’s outer surfaces has high mechanical resistance to wear, moisture, UV rays and the plant’s aggressive conditions and prevents rusting.

- Modular integration and optional equipment: Depending on the plant’s automation and occupational-health-and-safety (OHS) standards, the following can be integrated onto the silo: safe access lines — a backguard caged (protected) ship’s ladder and silo top-platform edge railings; environmental and pressure safety — a dust filter that filters the micronised particles rising during filling and a safety lid that damps sudden pressure surges; maintenance ease — a seal-gasketed man-access door for periodic internal cleaning, technical intervention and sampling; automation integration — high-precision level sensors transmitting instant fill and stock data to the plant’s PLC/SCADA system.

ENGINEERING NOTE

Round steel silos are the main base of raw-material and finished-product security in industrial milling plants. The strength calculations of the anchor systems and steel carrier legs are verified by computer-aided engineering analysis (FEA), taking into account the silo’s maximum static load capacity and possible seismic (earthquake) load indices. The low friction coefficient provided by the inner-surface epoxy coating breaks the flow resistance of cohesive materials such as flour and bran, prevents arching (bridging) inside the silo and guarantees the lower discharge equipment (discharge bottom, injector airlock, etc.) is fed at a stable volumetric flow.
