The Dynaflow Tubular Drag Chain Conveyor Is a Mechanical Drag Conveyor System Operating Within the Confines of a Pipe
Dynaflow Drag Chain Conveyors Features
Our Dynaflow Drag Chain Conveyors Are "Problem Solvers in a Pipeline"
A structural drag chain conveyor is designed for ultra-heavy-duty applications. The conveyor moves at a slower rate than other drag conveyors, but it can handle a wide range of often difficult-to-convey products. These industrial conveyor systems provide gentle handling and low material degradation. It is also completely enclosed and dust-free.
With this system, a series of straight and curved pipes are coupled to housings in a layout designed for your specific site and application requirements. The conveyor forms a circuit where the product can enter and exit through multiple chutes. When the drag chain conveyor is in motion, the discs drag material through the circuit, which is driven by a sprocket at one end. More sprockets can be added to the circuit to provide frictionless direction changes and reduce the system load.
Explore How It Works and the Benefits It Brings
Our Dynaflow Link & Pin Driven Tubular Drag Conveyor stands as a robust and heavy-duty mechanical system, encapsulated within a pipe. The discs, responsible for material transportation along the pipe, are anchored with durable metal links, making them apt for challenging applications. With the flexibility to be crafted from materials such as steel and cast iron, these conveyors can function efficiently at temperatures soaring up to 216°C (420°F).
Let’s discover other benefits you’ll enjoy with our conveyor belt solutions.
Our belt conveyor manufacturers take pride in offering a completely enclosed structural system that guarantees an environment free from dust and contamination during material transfer. This “totally enclosed” design serves as a robust barrier, preventing any potential release of dust, particulates, or contaminants into the surrounding area.
Implementing these conveyor technologies not only ensures the protection of the materials being conveyed but also promotes a clean and safe working environment for personnel.
Capable of handling a diverse range of materials, from dry and moist to fragile, cohesive, abrasive, hot, hygroscopic, and even sludge-like, the structural drag chain conveyors truly earn their title as the “problem solver in a pipe,” adeptly managing challenging material transfers.
In our conveyor system, materials are channeled into spaces created between the discs inside the conveying tube. As the chain and discs glide within this closed circuit, they gently usher the material to its designated outlet. Such a delicate transportation approach not only ensures minimal wear and tear on the product but also preserves its blend consistency.
When it comes to the ongoing operation of Dynaflow conveyors, you’ll find that maintenance is a breeze. These conveyor belt systems are engineered for robust performance and are designed to minimize the need for frequent maintenance tasks.
In fact, routine upkeep is kept to a bare minimum. To ensure the longevity and optimal performance of your Dynaflow conveyor, we recommend a simple monthly checkup, focusing primarily on inspecting the conveyor’s housings for any signs of wear or damage. This proactive approach ensures that any potential issues are identified and addressed promptly, allowing the conveyor to continue its reliable service.
A structural conveyor belt system can operate in three planes. The adaptable design of our system allows our engineers to craft intricate circuits, reducing transfer points and operating seamlessly with just one drive.
As a leader among conveyor systems manufacturers, Spiroflow is unique in that we offer three types of drag conveyors – Dynaflow drag conveyors as well as Chainflow and Cableflow conveyors. Our engineering team meticulously evaluates your specific application requirements, ensuring your conveyor operates reliably around the clock every day of the year.
If you have an application with multiple outlets and are looking for a single conveyor that can deliver the production material to multiple points, the drag chain and belt conveyor system is the perfect solution. There is also an option of installing multiple inlets, but only one can be operational at a time.
Regardless of the material volume, structural drag conveyors excel in energy efficiency, notably when contrasted with pneumatic conveying systems. Their low power consumption offers users significant energy savings and operational cost benefits.
Out flexible screw conveyor offers extended conveying distances of up to 200 ft. (60 m) per conveyor, extendable by linking multiple units. Enjoy the freedom to start and stop under load, run empty with most materials, and control product flow by flooding or metering. Mobile designs are available for various in-plant and loading applications, optimizing usage based on conveyor size.
With structural drag conveyor belts, no additional air is added to convey material, so there is no excess air at the outlet to filter for dust. Materials not released at one outlet simply continue their journey within the enclosed system, only to be discharged at the subsequent outlet.
Because tubular drag conveyors can operate in three (3) planes there is an endless number of layout options. Our engineers will evaluate your application requirements and site restrictions to determine the optimal layout. Typical circuits include the layouts below, however, this is by no means a complete list.

COMPONENTS & OPTIONS
Spiroflow’s Dynaflow structural drag chain conveyor is designed to achieve gentle handling and low material degradation. A series of straight and curved pipes coupled to housings form a circuit where the product can enter and exit through pipe mounted chutes. Conveying is achieved when material enters the space between the discs that is contained within the circuit. The chain and discs are dragged through the circuit by a drive motor. Changes in direction are accomplished with pipe bends and/or 90°/180° idler housing assemblies.

CAPACITY & SELECTION
Dynaflow Structural Drag Conveyors can operate at rates up to 50 ft./min / 15m/min depending on material characteristics & layout. Capacities are typically up to 10 ft3/min. / 0.28 m3/min.
The capacity charts below allow you to roughly estimate the size of the conveyor and the speed based on the throughput requirements in cubic feet/minute or cubic liters/minute. The horizontal lines represent the velocity at which your product will pass through the conveyor. The vertical lines indicate the volumetric throughput rate in liters per minute. The diagonal lines are the sizes of the conveyors available.
But don’t think you have to figure out which drag conveyor will work best for your application. Our sales engineers can do that for you!
Tubular Drag Conveyor Selection Guidelines
- The Dynaflow drag conveyor can operate at speeds up to 50 ft./min (15 m/min).
- Smaller conveyor sizes and faster speeds are usually selected when the material is free-flowing and non-abrasive and/or the equipment duty cycle is low.
- Future capacity requirements should be considered. It may be prudent to install a larger conveyor now at a lower speed. You can increase the speed later to accommodate a higher capacity. This can be done with the use of a variable frequency drive or gearing change.
- Surges and uneven feed conditions should be considered. Surge hoppers may provide more constant feeding and may enable the use of a smaller conveyor.
