Animal feed silo

galvanised steelhopperoutdoor

Product overview
Modular feed silo designed for efficient storage and controlled discharge of livestock feed in farm facilities. Configurable diameters and hopper options to fit project requirements. Structural calculations can be supplied according to Eurocode or equivalent standards.

Applications and adaptability
Suitable for farms and livestock buildings for bulk storage of compound feed, cereals and concentrates. Design and capacity adapted to site requirements; multiple unloading and distribution configurations supported.

Main features

• Available diameters: 1.8 m, 2.10 m, 2.55 m, 2.75 m, 3.2 m, 3.8 m
• Capacities: from 4 m³ up to 86 m³
• Steel grades: S450GD (primary); roof/cover parts S280GD or as specified
• Galvanisation: Z600 g/m² typical; HDG options for specific parts

Standard components and roof
Standard supply includes trapezoidal roof sectors, semi-automatic lids, loading collar, hopper sectors, bodysheets (virolas), lower support structure, legs (omega profile) and bracing as required by chosen configuration.

Design and technical notes

• Lower ribbing and reinforced connections for optimum structural performance
• Precision-manufactured sectors with formed edges for accurate assembly
• Typical roof pitch: 30º (trapezoidal sectors)
• Pressure seal option for pneumatic loading to minimise dust emissions

Loading and unloading options
Configurable with pneumatic loading systems, loading collars, hopper outlets with 45º/60º/67º inclinations, discharge collars and gates (manual, electric, pneumatic or dual actuation). Side-discharge systems, sweep augers and delivery structures available as options.

Accessories and additional systems

• Roof handrails and catwalks, semi-automatic lids, loading collars
• Level viewers and sensors (rotary, pendulum, capacitive), aeration systems (fans, vents, gutters)
• Hopper aeration, access ladders and platforms, anchorage and bolting options (ZiNi, HDG)
• Dosing and distribution equipment: flex augers, chain systems, distribution heads

Components shown

• Trapezoidal roof sector (steel)
• Loading collar (DC04; HDG galvanisation)
• Semi-automatic cover (S280GD; Z600; typical thickness e = 2 mm)
• Hopper sectors inclinations 45º / 60º / 67º; example discharge collar Ø 445 mm at 900 mm
• Virolas / bodysheets (S450GD; Z600; typical thickness e = 0.8–1 mm)
• Lower supporting structure and legs (omega profile legs; bracing with cold-formed U-pillars; anchor plates)

Notes
Design, component gauges and coatings vary by selected model and capacity; structural calculations can be prepared to Eurocode EN standards or equivalent local norms.
