Sizing a Tubular Chain Conveyor: Capacity, Material Type, and Route Planning Explained

Because a tubular chain conveyor's core value is enclosed, gentle, multi-plane transfer, sizing it correctly means matching pipe diameter and routing to your actual material and site layout — not defaulting to a standard diameter and hoping the routing works out.

Key Specifications

The routing capability is the specification that most differentiates tubular chain conveying from other enclosed transfer methods — a single continuous run can combine horizontal, vertical, and diagonal sections, avoiding the multiple transfer points a belt or screw conveyor route would need to cover the same path.

Operating Characteristics

The system operates as "enclosed, multi-plane conveying" using "a continuous chain with disc flights through a sealed pipe." Key performance characteristics:

• Speed profile: gentle handling at low velocity, minimizing degradation compared to higher-speed mechanical or pneumatic transfer
• Moisture pickup: none — no air exposure during transit means no risk of hygroscopic moisture gain
• Product aeration: zero risk, relevant for materials where fluffing or aeration during transfer affects downstream handling or dosing accuracy

Material Compatibility

Tubular chain conveying is optimized for fragile, dusty, or hazardous materials — specifically named applications include oleochemical materials (soap noodles, fatty acids), food ingredients, chemical and explosive dusts, and pharmaceutical APIs and excipients. The common thread across these applications is material sensitivity: to degradation, to contamination, to moisture, or to environmental exposure.

Energy and Utility Requirements

Because the system needs no compressed air supply (unlike pneumatic conveying) and runs at low velocity with correspondingly low energy consumption, utility requirements are simpler to plan for than a pneumatic alternative — one less compressed air line to size and maintain.

What This Spec Doesn't Cover

Weight capacity and throughput rates for tubular chain conveying are highly material-dependent — chain speed, disc spacing, and pipe diameter all interact with your specific material's bulk density and particle characteristics to determine actual tonnes-per-hour capacity. There's no single "standard capacity" figure that applies across all materials, which is why this is one of the first things to clarify directly with your supplier rather than assume from a generic spec sheet.

What to Send With Your Enquiry

A complete tubular chain conveyor spec starts with: material bulk density and fragility/friability, required throughput, full routing path including all direction changes and elevation, and any hygiene, purity, or hazardous-dust containment requirements.
