Pneumatic Conveying

The pneumatic transport It is an industrial technology used for the controlled conveyance of bulk, granular, and powdery materials through streams of air or gas within dedicated pipelines. This system allows for the continuous, safe, and efficient transfer of material between different plant sections, reducing leaks, contamination, and plant footprint.

Thanks to the ability to develop even complex horizontal and vertical paths, pneumatic conveying represents a widely used solution in industrial processes that require high operational continuity, controlled flow management, and integration with dosing, filtration, separation, and storage systems.

Pneumatic systems can operate according to different transport modes:

• dilute phase conveying, in which the material is moved at high velocity within the gaseous flow with low product concentrations;
• dense phase transport, characterized by low velocities and high material concentrations, particularly indicated for reducing product degradation and line wear;
• pressure or vacuum transport, used according to the needs of feeding, recovery, and distribution of material within the plant.

During operation, the continuous impact of particles against the internal surfaces of the pipes and the high flow velocity generate particularly intense abrasion and erosion phenomena, especially at points of change in direction, in bends, cyclones, diverters, and in feed and discharge areas.

The areas most subject to wear are particularly:

• Pneumatic piping and transport curves
• Cyclones and separation chambers
• diverters and distribution valves
• Power and discharge lines material
• silos and product receiving systems
• surfaces subject to severe erosion from high-velocity flow

In these contexts, SWIMSUIT intervenes with anti-wear solutions designed to protect the most stressed components, increase the operational life of the lines, and improve the reliability and efficiency of pneumatic conveying systems.

SARO develops anti-wear measures through the application of:

• High abrasion-resistant ceramic coatings – SARCER & SARMOS
• Bends and wear-resistant technical components – SARCER Bends & Tubes – HEXAGON & TETRAGON HOSE
• Fittings and components – SAROMAX FITTINGS & PIPES – SAROMAX100
• Ceramic-filled resins for surface restoration and protection – RESINALCERAMICA T250 A/B
• integrated solutions designed for high-speed environments subject to mechanical stress

Solutions are designed based on the characteristics of the material being conveyed, process speeds, operating pressures, material concentrations, and plant operating conditions, with the aim of:

• reduce frequent maintenance and replacements
• improve operational continuity and plant efficiency
• ensure the reliability and stability of pneumatic conveying processes

Pneumatic transport systems are used in numerous industrial sectors for the management of:

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

SARO operates in compliance with the technical specifications and major regulations applicable to industrial dust handling and containment systems, supporting complex plants with anti-wear technical solutions designed for real operating conditions and specific process needs.
