What are the different types of drag chain conveyors?

Two Varieties of Drag Chain Conveyors

Drag chain conveyors stand out as the most efficient method for transporting or lifting bulk material and shifting it from one location to another. The arrangement, layout configurations, service duty rating, drive size, as well as the type of chain, and flight assembly, are all elements that greatly impact the quality, robustness, and lifespan of any drag conveyor.

The expression “drag chain conveyor” is commonly used in the material handling field. Two variations exist within this category of bulk material handling equipment: standard drag chain conveyors and en-masse drag chain conveyors.

Versatile Operation of Drag Chain Conveyors

Drag chain conveyors are an ideal option for bulk handling, energy generation, cement production, and mineral processing industries to minimize material deterioration and decrease material wastage thanks to the closed container. Both types of drag chain conveyors operate on the principle of moving materials with a skeletal chain and flight assembly along the lower part of an enclosed casing.

Drag chain conveyors and en-masse drag chain conveyors demonstrate superior efficiency in maximizing space utilization within the conveyor housing compared to belt and screw conveyors. Specifically, drag chain conveyors utilize close to 50% of the space for material movement, while en-masse drag chain conveyors can utilize up to 90%. On the other hand, belt conveyors utilize approximately 20% of the available space, and screw conveyors use around 45%.

The significant space efficiency of drag chain conveyors allows them to transport a greater volume of material within a compact area, which can be beneficial for facilities with space limitations. Moreover, these conveyors operate at lower speeds, requiring less power and resulting in reduced equipment wear and lower energy consumption, leading to decreased operating expenses.

Drag chain conveyors have an additional advantage in their design versatility. They can transport materials horizontally, on inclines, or vertically. The choice of flight type used determines the direction. This layout flexibility is critical for industries that prioritize space and material handling efficiency. Choosing the appropriate flight type is crucial. It optimizes the conveyor system for specific material movement needs, whether horizontal, inclined, or vertical.

What are some drag conveyor components?


The central component of a drag conveyor is its chain. This is not just any chain; it is a heavy-duty, intricately engineered marvel created to endure the challenges of transporting materials such as grains, coal, or aggregates. The design of the chain guarantees minimal friction and wear, resulting in a longer lifespan and reduced maintenance expenses. Jingwei provides a wide range of bush roller chains for scraper and drag conveyors. We can tailor the specifications you require, from the material to the size, to perfectly match your needs. Feel free to reach out to us with your inquiries.


Connected to the chain are flights, which are the workhorses responsible for physically pushing or dragging materials along the conveyor. Flights come in various materials and designs, customized to suit the specific properties of the materials being conveyed. Whether it is high-impact plastics for gentle handling of grains or hardened steel for abrasive materials, selecting the appropriate flight material is vital for efficiency and durability. Our flights are manufactured according to your requirements as we have our own factory and design team. Rather than investing in low-quality flights, approach us to discuss ordering bulk flights at competitive prices.


Driving the chain and flights are the sprockets. Positioned at the ends of the conveyor, sprockets engage with the chain, supplying the necessary power to transport materials. Ensuring proper alignment and maintenance of sprockets is crucial for smooth operation and to avoid unnecessary wear on the chain and sprockets themselves. At Jingwei, we have developed our nylon sprockets and stainless steel sprockets to significantly enhance wear resistance and strength, thereby improving the efficiency of your conveyors.


The trough of the conveyor holds the chain and flights, guiding them along the intended path. Troughs can be designed to suit various conditions, including dust-tight environments to prevent material loss and contamination. The material and design of the trough play a vital role in the overall efficiency and safety of the conveyor.

Inlets and Outlets

Entry and exit points of materials on the conveyor are the inlets and outlets respectively. These components can be personalized to align with the layout and needs of any operation, ensuring smooth integration with other equipment. Proper design guarantees efficient material flow and prevents bottlenecks or spillage.

Motors and Reducers

Providing the power to transport materials are the motors and reducers. These components are chosen based on factors such as the conveyor’s length, the material weight being moved, and the required operational speed. Energy-efficient motors and appropriately sized reducers can notably reduce operational expenses.

Custom Conveyor Chain Sprocket Design

A well-designed sprocket ensures smooth operation, minimal wear on the chain, and reliable performance under various operational conditions.

That’s why we customize sprockets that include features such as induction-hardened teeth for extra durability, special mounting holes, or unique profiles for specific types of chains.

Our engineering process involves calculating the load requirements, analyzing the speed and torque needs, and ensuring compatibility with the conveyor system’s overall design. The goal is to optimize the sprocket’s performance for your specific application, whether it involves heavy loads, high speeds, or challenging environmental conditions.
