Silage Bends

Diverter elbows are fundamental components in pneumatic conveying systems used for managing the final loading phase of bulk and powdery materials into storage silos. Their function is to divert and slow down the flow of material before it enters the silo, ensuring controlled product distribution and reducing impact, turbulence, and erosion phenomena.

These components operate under particularly harsh conditions, as the material reaches high speeds and strong flow concentrations in the final stage of pneumatic transport. Silo bends therefore represent one of the most critical points of the plant from a wear perspective.

Proper curve design allows for:

• reduce the impact speed of the material
• limit turbulence and pressure loss
• improve product distribution in the silo
• contain phenomena of granulometric degradation
• increase the operating life of transport lines

Silage curves are particularly useful in the pneumatic conveying of:

• light and heavy ashes
• coal dust
• secondary solid fuels (CSS)
• abrasive mineral materials
• industrial dusts
• granules and plastic materials
• products from material recovery and treatment processes

During operation, the areas most subject to wear are:

• curved extrados
• material impact points
• Slow flow zones
• Inlet and outlet fittings
• connections with silos and piping
• surfaces subject to continuous erosion from high velocity

In these contexts, SARO intervenes with anti-wear solutions designed to increase the operational life of silage curves, improve pneumatic transport efficiency, and reduce maintenance and plant downtime.

SARO develops anti-wear solutions through:

• High-abrasion-resistant ceramic coatings in SARCER & SARMOS
• Anti-wear technical curves – SARCER CURVES
• Curves and coatings – SAROMAX CURVE – SAROMAX100

Solutions are designed considering:

• Type of material transported
• abrasiveness and grit
• transport speed and pressure
• flow rate and concentration
• pneumatic line geometry
• Silo configuration and operating conditions

SARO supports complex industrial plants in the design and optimization of pneumatic conveying lines and silo storage, developing wear-resistant solutions tailored to real operating conditions and specific process needs.
